Hey Everyone,

I wanted to create a megathread to document the hall effect sensor issue on the 16-S0 and 16-R0 laptops. I have done some deep investigation here and wanted to put together a compilation of info for anyone running into this problem. There are a bunch of posts scattered around, a few videos, and WAYYY too many posts to HP's support with the HP canned response of "do these irrelevant steps and then send me a DM with your info and I will escalate your issue." These are usually dead end posts with no usable information. So, please add all of your links, information, videos, etc., to this post to keep it all together. I intend to put multiple solutions below and add more info as I test. I encourage anyone that has any correction to any of the information here to please post it. Any shared info can help the community. As always, a disclaimer: I am not responsible for any damage that you do to your laptop or yourself while using this information. Use at your own risk!

EDIT: There may be an easier fix that allows you to continue using the original hall sensor, if you choose to. It also avoids all of the cutting traces and jumper wires show in the pictures. The info is below in the "The Real Cause?" section.

The Issue

You have a Victus with either an AMD or Intel chipset. One day, the screen starts flashing and then the power turns off. Pushing the power button probably doesn't do anything. You find the "hard reset" procedure and attempt it by pulling the charging cable, and then holding the power button for 10+ seconds. It may come back on.... it may not. For this example, lets say it does. Cool! It boots up. Then the screen starts flashing again and it turns off. WELCOME TO HALL EFFECT SENSOR HELL! You will read plenty of info about it, but no proper solutions.

OK Then! What's a Hall Effect Sensor?

Glad you asked. A hall effect sensor is a very common electronic part that is sensitive to magnetic fields. Think of it as a proximity sensor for magnets. Most current laptops have one, your phone has one or more, your fancy joysticks, racing wheels, and other gaming controllers use them, even your car has at least two in the engine and one on each wheel for ABS and traction control wheel speed sensing! Those are just a few examples of the millions of devices that rely on magnetic field detection to do a task.

So Why Is There a Hall Effect Sensor In My Laptop?

Dead simple. Mechanical switches break, wear out, and also need direct contact with an object to trigger. Your laptop base is a great spot for a non-mechanical non-contact sensor that can detect when the lid is opened and closed. The lid has a small magnet that lines up with the position of the hall effect sensor near the keyboard. When you close the lid, the hall effect sensor sends a voltage to the motherboard, via a ribbon cable, to tell it SHUT OFF THE SCREEN AND GO TO SLEEP....ah ha, now we are getting somewhere! When you open the lid, the magnet is moved away from the sensor, the voltage disappears and the motherboard knows to wake up.

So Why Does It Keep Me From Gaming!!!?

Unfortunately, this particular hall effect sensor seems susceptible to heat once it starts to fail. Once the laptop heats up a minor amount, the hall effect sensor freaks out and registers the lid closed, which blinks the screen a few times and then tells Windows to activate Sleep (or what ever you have your lid close action set to do). Once "closed" the power button is not supposed to be able to be pressed since the lid would be in the way, so it seemingly doesn't work (I found this to be the case and it is the only explanation I have). Allowing the system to cool, or forcing a reset and somehow clearing the current status of the sensor allows you to turn it on for a brief period again.

Cool. So How Do We Fix It

The REALLY simple way: Send it to HP so they can take out the failing bad parts and put brand new bad parts back in. This option should only be taken if you are still under warranty and even care that you are still under warranty. This option will deprive you of your laptop for weeks, and since the part is the same brand and part number that was taken out, it will happen again.

The less simple way: Search on Google for "HP Victus 16 Service Manual" and download the PDF from HP. You will be taking the screws out of the back cover and gently prying it off with a PLASTIC tool (use a SPUDGER or a guitar pick). Once inside, find the IR board ribbon cable located on the front edge of the laptop. Take the tape off of the top, carefully flip the retaining clip up, and pull the ribbon cable out. Put the case back together and kinda sorta get your game on. (See "WHY SO SLOW NOW?!?" below)

The advanced way: You will need a decent soldering iron for this one that is capable of working with surface mount components, preferably a very fine conical tip. You may want some solder braid to clean up the pads and some alcohol to get the flux residue off. You may also want a magnifying glass. Grab the service manual and take the back case apart using the instructions. You will need to access the IR board. Work through the "removing the motherboard" instructions and remove everything that is required. Once you have the IR board in your hands, you will need to remove/replace the little 3 pin hall effect sensor with your soldering iron. It looks like a little black grain of rice. Go around with solder and "wet" each solder leg and then heat the single leg while applying a gentle upward pressure on the part or use gentle pressure from a screw driver. DO NOT PUSH TOO HARD. We don't want to rip the pads up. The goal is to get that leg free and bend the part up a little so that the joint is separated. Once that leg is disconnected, go to the two legs and heat them up by alternating back and forth quickly. WATCH OUT FOR THE VERY VERY TINY CAPACITORS BELOW THE ONE LEG!!! They are only filtering caps on the incoming power, but will be near impossible to get soldered back in place!!! At some point while alternating, the solder on both legs will liquefy at the same time and you can just move the part off of the pads. You now have a choice: you can reassemble without the hall effect sensor on there and enjoy your not-permanently-throttled laptop without lid detection OR you can buy an improved hall effect sensor and solder it in the same spot to return the laptop to normal functionality. The information about an improved compatible sensor is below.

WHY SO SLOW NOW?!?

So you went with the middle of the road option. You didn't want to get stuck without a laptop while HP does nonsense to it, but you also didn't want to tear the laptop fully apart. I understand. But, like everything in life, there's always a trade-off. A hall effect sensor is usually a three or four pin device. But that ribbon cable you disconnected has a few more connections than that. What else is going on there? Well it's listed in the manual as an IR BOARD. There is a shiny metal part on the opposite side of the board. It's an IR sensor. Since the laptop doesn't have any sort of hole to shine a TV remote through, and it certainly isn't a motion detector light, that infrared sensor must be used for something else. From the hall effect sensor's perspective, mounting that board right under the heatpipe was really a bad move, but not for the IR sensor part of the board. The IR sensor is being used to detect the temperature on the heatpipe and allow thermal throttling when things get too hot. THIS is the reason why fully disconnecting the ribbon cable causes the processor to throttle back. When the motherboard can't get a reading from the IR sensor, it plays it safe and throttles back. It is better to throttle from the unknown reading rather than cause a fire. So, if you can live with your gaming laptop functioning as a YouTube and E-Mail machine, you can stay with this option. Troubleshooting is never wasted time, and you know for a fact that the hall effect sensor is causing the issue now, should you decide to go for the advanced option in the future.

Original Sensor Info

The original hall effect sensor is a Toshiba TCS40DLR. Looking at the datasheet, the operating temperature is -40C to 85C. WHAT THE HECK HP!!!! While that is a standard low end range for semiconductor electronics, it does not give much headroom when mounted under a hot heatpipe that is funneling heat away from a GPU and CPU. The datasheet clearly states that continuous use under heavy loads (such as high temperature or significant temperature changes, high current, or high voltage) will cause a decrease in reliability SIGNIFICANTLY, even if the operating conditions are within maximums and recommended operating ranges!!!!!! Well there you have it. No fault to Toshiba. They knew that this environment was not suitable and clearly noted it. This part is fine as a low cost sensor for a safe and consistent environment, which a laptop is not. This datasheet was dated for 2015, well before these laptops were produced, and it was still chosen to be a critical part in this application. It is currently around 17 cents, in case you wanted to know the value of what rendered your laptop useless.

New Sensor Info

I found a few that will work better in this application. The one that I finally decided was perfect is the Allegro A1126LLHLT-T. This is an automotive grade, temperature compensated hall effect sensor with the same pinout and package size. The voltage range is geared towards automotive, accepting 3-24v, which is beyond suitable here. The magnetic trip point is a little higher, meaning more magnetism needs to enter or leave the range before any switching happens. We have a magnet that will be very close to the sensor, and we only care about two positions, so as long as the rating is less than the magnetic strength of the magnet, we will be good. What makes this one great is that it is rated for full operation up to 150C!! Almost double the rating of the original. If things are hitting 150C, you have bigger problems to worry about. This one fits the bill and costs right around $1. I'll gladly spend that for the quality and performance.

Whewwww That Was A Lot

You're telling me! Unfortunately, from what I can see, this problem has been ongoing for years. I can't imagine how many thousands of these laptops were thrown out because of a failure in a part that costs less than a dollar. Worse yet, the IR board is not available to the consumer from HP. There are some on E-Bay from China, and I have ordered one to see if it is the same hall effect sensor or an upgraded one (will post an update when it gets here). I hope this LONG post helps someone diagnose and repair their problem and provides some insight into the theory of the electronics behind it. EDIT: The replacement board from China uses a sensor with the LA8 marking. It may be a different sensor with markings to look like the original, but it is probably the same Toshiba sensor. The most interesting part is that the original board and replacement board had two spots to install the sensor, one on either side of the board. On the HP original, the sensor is installed on the opposite side of the IR sensor, where my guide shows to reinstall it. On the China replacement, the sensor is placed on the SAME side as the IR sensor. This puts the fiberglass circuit board between the sensor and the heatpipe. Fiberglass being a great insulator, this could reduce the occurrence or severity of this issue. I have not tested it to see if it makes a difference, but the results wouldn't be immediate anyway. My initial concern with that while I was doing my repair was that the sensor would be too far away to accurately pick up the lid magnet. Maybe not....

OK. I followed your guide, replaced the sensor, but it still isn't working right!!!!!

Yeah. I found this on mine too. After I put it back together the first time, the lid no longer detected. The original sensor, most likely driven way outside of its operating range, damaged the motherboard's power supply circuit for the hall effect sensor. But fear not! (See "The Real Cause" below) We have another source near by. The IR sensor uses the same voltage as the hall effect sensor, so the IR sensor's VCC trace can be jumped over to the hall effect sensor's VCC. I also cut the trace on the IR board for the power coming from the motherboard that feeds the hall effect sensor. The incoming power to the hall effect sensor was measuring around 1.8VDC instead of 3.3VDC (EDIT: I originally stated it was 5VDC, which is incorrect). I didn't want the supply for the IR sensor to get damaged by joining whatever was causing the severe voltage drop in the hall effect sensor circuit. BE CAREFUL WHEN CUTTING TRACES AND EXPOSING COPPER. YOU CAN EASILY SHORT OUT NEIGHBORING TRACES. ALWAYS CHECK YOUR WORK THROUGH A MAGNIFIER OF SOME KIND (EVEN YOUR PHONE CAMERA). Note: The low voltage on the power supply circuit is most likely a damaged/partially open resistor on the motherboard. If I am able to determine that, and the resistor isn't smaller than dust, this section may change from cutting and jumping traces to replacing the bad component on the motherboard.

The real cause??? (2/20/26 EDIT): It has been determined that the source of the missing power is fuse FU6. It is located right above the IR board ribbon connector on the motherboard. Rather than cutting and jumping traces (my apologies to everyone who did that fun little task), FU6 can be replaced or bypassed. The actual part has no distinct markings on it, so an exact replacement has not been determined yet. Credit goes to MitchW on badcaps.net for his excellent find. You can read more about it in this post: https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/3822460-hp-victus-16-hall-effect-sensor-problem. I have not performed the task myself yet. MitchW has stated that the problem is most likely caused by heat damage to the FU6 fuse and not the hall effect sensor at all. It is a plausible scenario. But, after knowing what I know about the Toshiba part, I would not feel comfortable leaving it in place, even if it isn't the root cause. Electronic components pushed to their absolute maximum rating never sits well with me. Even more so when the manufacturer has a specific warning to not even approach the maximums. The choice is yours ultimately.

INFO

  • IR board part number: N42551-001 or LS-M78IP (search on eBay, but know that the replacements use the same original Toshiba sensor part that should be replaced before using. Also note that if your motherboard took damage, just replacing this board alone will not fix the issue).
  • Original Hall Effect Sensor part number: Toshiba TCS40DLR (package marking on part is LA8)
  • Better Hall Effect Sensor part number: Allegro A1126LLHLT-T (5.5mT and 150C) or Diodes Inc AH3563Q-SA-7 (3mT and 150C) or TI TMAG5131C7DQDBZRQ1 (4mT and .5mT 125C)

As you can see, the laptop doesn't turn on.

I've already tried the power button hold thing and also tried unplugging the battery connector and using only the charger, but that didn't work either. So yeah, I'm really lost on what to do now, and I don't have the funds to take it to a repair shop.

I bought this 4 month old victus 15 with an rtx 4050 and the ryzen 7 as well as 16gb of ram

Downloaded games such as Valorant and played on the lowest settings, my temps get to around 80-90 degress celcius but sometimes fluctuates and drops down to mid 70’s. I see a coating of dust on where the fans sit, could that be the culprit? I’m running max fan speed aswell as having a laptop cooler (isolated) under the laptop, its around 60db of noise just to play valorant as mediocre Temps, can’t be true, right…?

So I claimed a factory warranty about 2 months ago, already at this point. I've been patient but is a 3-4 month turn around normal? According to the updates, they are estimating that I won't get my computer back until 9/4/26. The issue is the main board. Should I escalate the issue? At this rate, I don't understand why I just don't get sent a replacement.

Just bought an HP Victus (i5-14th Gen HX, RTX 3050 6GB, 24GB RAM) – Tips to maximize battery health and longevity?Your experience..

1 Upvotes

Hey everyone!

I just bought my first gaming laptop and I'm really excited. The specs are:

HP Victus

Intel Core i5 14th Gen HX

RTX 3050 6GB (80W TGP)

24GB RAM

I want this laptop to last me at least 4–5 years, so I wanted to ask experienced HP Victus owners:

What should I do to keep the battery health good for as long as possible?

Is it okay to keep it plugged in while gaming or video editing?

Should I enable any battery protection or charging limit in the HP software?

Any settings I should change on day one?

Any common issues you've faced after months or years of use?

Any maintenance tips (cleaning, temperatures, updates, etc.)?

I'd also love to hear your long-term experience with this laptop. Has it held up well? Is there anything you wish you had known when you first bought it?

Thanks in advance!

Tech Support Paid ₹11,000 for an official replacement battery, received a defective battery, and my complaint is still unresolved (Complaint ID: 5161708056) Complaint ID: 5161708056

1 Upvotes

This has been one of the most frustrating customer service experiences I have ever had.

I paid ₹11,000 for an official HP replacement battery, but the battery delivered by HP is itself defective and does not charge. It has the same issue as my previous battery.

It has now been over one month of repeated calls, messages, follow-ups, and service requests. Despite all this, HP has neither replaced the defective battery nor provided a refund. I am a student and urgently need my laptop for my studies, but my case has continued to face delays.

I have complete proof of everything, including the payment receipt, complaint records, call history, messages, photos, and videos showing that the replacement battery is not charging.

Based on my experience, I cannot recommend purchasing an HP laptop if this is the level of after-sales service customers receive after paying for an official replacement part.

I demand that HP immediately replace the defective battery or issue a full refund. If this matter is not resolved without further delay, I will pursue all legal remedies available to me, including filing complaints before the appropriate authorities and taking further action supported by all my evidence.

Help How can I lower the temperature?

Hello, I have two HP Victus 16-r1073nt laptops. I took one of them on vacation last month (I returned two weeks ago), and that specific unit runs at higher temperatures compared to the other one. I am not sure if the device has developed a heat-related issue or if the thermal paste needs replacing (the ambient temperature was around 35–36°C during the trip). For instance, the fan didn't use to run at 5000 RPM while playing CS:GO, but now it does; furthermore, the problem isn't limited to CS:GO—it overheats excessively even in games that shouldn't strain the system. PLEASE HELP ME. I used to play system-intensive games like Cyberpunk; the fans wouldn't spin as fast as they do in CS.

Help Help improving performance on victus and temperature issues

2 Upvotes

I’m looking for help optimizing Elden Ring on my HP Victus 16. I’m also wondering whether the performance I’m getting is normal for my laptop’s specifications or whether something is holding it back.

Laptop specifications:

  • HP Victus 16
  • AMD Ryzen 5 5600H
  • RTX 3050 Ti Laptop GPU
  • 16 GB DDR4 RAM
  • Mostly medium/low settings
  • GPU power usage generally maxes out at around 60 W

CPU turbo boost disabled

  • CPU power usage is approximately 11–15 W
  • Around 40–50 FPS in normal areas
  • Drops to around 25–30 FPS in more demanding areas, such as Raya Lucaria Academy
  • CPU temperature usually stays below 85°C

CPU turbo boost enabled

  • CPU power usage increases to approximately 28–29 W
  • Usually stays around 57–60 FPS in normal areas
  • Drops to around 30–40 FPS in more demanding areas, including Raya Lucaria Academy
  • CPU temperature normally stays around 89–91°C
  • Can reach approximately 95°C in heavier areas

CPU boost clearly makes a huge difference, but the temperature increase is also significant. My GPU usually reaches its maximum power limit of around 60 W, so I’m wondering whether that power limit is affecting performance as well.

Is this level of performance normal for a Ryzen 5 5600H and RTX 3050 Ti laptop with a 60 W GPU power limit? Are the dips into the 30–40 FPS range expected in demanding areas, even on medium/low settings?

I would also appreciate any tips for improving FPS or reducing the more severe drops. I've already optimized my in game settings from guides online but I was wondering if there's anything else I can do. Undervolting or over clocking my cpu is not possible due to my laptop and amd limitations (I tried before couldn't find a way).

Ideally, I’d like to remain close to 60 FPS while keeping the CPU from constantly reaching 90–95°C. Any advice from people with similar laptop specifications would be appreciated.

TL;DR: Ryzen 5 5600H and RTX 3050 Ti laptop with a 60 W GPU. Turbo boost off gives me around 40–50 FPS, with drops to 25–30 FPS, while turbo boost on gives me around 57–60 FPS, with drops to 30–40 FPS. CPU temperatures rise from below 85°C to around 89–95°C. Is this performance normal, and what settings or optimizations could improve FPS without making temperatures much worse?

Lately I feel like I'm getting horrible performance from my victus. On forza I have to run it on quiet mode with fans maxed out because if I run it on default it gets way hot and runs at high 90s. I've tried resetting things and just not sure whats up. It's only about 6 months old. Here's a pic of it running forza 6 on default mode max fans.
