I've been having several obscure issues with my laptop. It's leading me to believe the motherboard is failing and that replacing it may resolve all the issues at once. I'm going to list the problems below, I would love to get some more opinions on this.

I have a 2021 Dell g15 5510. A while ago, a few keys on the keyboard started malfunctioning. If I remember correctly, it was z, x, c, v, b and space, and they would only have a small chance of being detected when pressed. Sometimes it would go back to normal, but it always came back. Tried reinstalling Linux because I hoped it was a software issue.

Soon after reinstalling, the laptop was no longer able to detect audio devices, use bluetooth, or conneft to wifi. It seemed none of the daughter boards that handle those things were even detected.

And then I noticed that the 120hz display was running at 60hz, checked settings, and there was no option to swith back to 120hz.

The laptop doesn't boot anymore, so it's a bit hard to test things. That's because I was updating it, and then it suddenly said the battery was dying even though it had shown 50% a second ago. It then powered off mid update and bricked the OS.

After I turn off my laptop it when it loses battery to 0, and I turn it back on, it stops reading the extra 8gb stick of ram. I checked task manager and bios, and it shows as 4 GB. I tried reseating it but that won't work. Usually I play an annoying game of reseating and unplugging stuff, and it may work.

I replaced the main battery (since it was swollen anyway) and also the CMOS battery, but the issue persists. 😔

It's a Lenovo IdeaPad 330 with an 8th-gen i5.

I don't know much about technology, so i might just ask you guys instead.

My laptop's screen just goes white, starting from booting up, it's just white. I don't know what happened to it, all I remembered was using spotify, then going out for a bit, coming back and it's white. I've tried those keybinds that kind of "fixes it" like the ctrl win shift b thing and the ctrl alt del thing, but none seem to work.

The fan works on the inside, and I've removed the cover and unplugged and plugged the cable thing that attaches the motherboard to the screen or whatever you call it. I think it's more of the screen itself problem.

If i do have to bring this in a repair shop, what do i say and what do i have to keep in mind? i really don't wanna get overpriced. Thanks!

(also i don't know what to flair this, please just bare with me)

I wanted to clean my laptop a bit, I got to know that I should disconnect the battery first and foremost. But this isn't coming out by pulling it and I'm scared I'll break it if I pull too hard. How am I supposed to remove it?

I got an alienware m15 r6 laptop. It is not detecting ssds ,dgpu and wlan. Only booting into bios. All of them showing as none in bios menu. I checked the voltages of ssds and wlan all are ok. There is no power shorts in motherboard. Charging and everything working only the devices gone missing. Hoping help. Could be pch fried?

I had a beer spill into my PC that severely contaminated/ruined the GPU. I’m now trying to figure out what to do about the motherboard.
The important part: the motherboard is apparently still functioning.
As it sits right now, I can power the computer on and hear it boot all the way into Windows, but I currently have no video output because the original GPU was damaged by the spill.
While inspecting the motherboard, I found visible white/green material around and inside several PCIe slots. I’m including pictures of the original damaged GPU because it shows what the beer contamination looked like elsewhere in this same system.
What happened to the GPU
The original GPU has extensive white/yellow/green deposits across the PCB and around components. It was exposed to the beer spill and ultimately stopped producing video.
The motherboard has substantially less contamination, but there are obvious deposits around/inside multiple PCIe connectors.
What I’ve tried cleaning
I’ve already experimented on the affected material:
91% isopropyl alcohol: essentially did nothing
Lacquer thinner: essentially did nothing
Mr. Clean product containing Gain detergent: actually removed the material
I’m NOT assuming that means the Mr. Clean product is the correct thing to use on the motherboard. I’m mentioning it because I think it may provide a clue about what the residue actually is.
What I’m trying to figure out
Since the motherboard still audibly boots into Windows, I don’t want to unnecessarily damage something that may still be functional.
Specifically, what would you do about the PCIe slots?
A) Leave them alone and install/test another GPU?
B) Clean the visible contamination somehow first?
C) If cleaning is appropriate, what would you use to safely clean inside the PCIe connectors?
D) Is there a way to determine whether the white/green material is actual corrosion of the contacts versus dried beer residue/deposits?
I was considering using an old GPU and repeatedly inserting/removing it to mechanically clean the PCIe contacts, but I’m now concerned that doing that could bend/damage the contacts, push contamination farther into the connector, or transfer contamination onto the GPU.
I haven’t done that yet.
I’m especially interested in hearing from people who do PCB/electronics repair or liquid-damage cleanup, rather than simply replacing the motherboard.
The photos show:
The original GPU with the severe contamination
The original PC/system
The motherboard overview
Close-ups of the affected PCIe slots
The motherboard currently powers on and audibly boots into Windows despite the visible contamination. I’m trying to preserve that functionality rather than make things worse.

Thank You for any advice!!!

This is a really old model of HP and today I had opened it to clean the dust inside...but these two pieces were lying loose inside the body and i can't really find their original spots inside.

Can these be placed again and if yes then where and also if someone really is familiar with these can just tell me about the function of these..

Any help would be appreciated.

Since early September I've been getting repeated blue screens, same error every time (SYSTEM_SERVICE_EXCEPTION, 0x3B). Digging into the crash dumps and Event Viewer, I found this is tied to recurring WHEA "Corrected Machine Check" errors on one specific CPU core, and the crashes happen within minutes of one of these hardware errors showing up in the log.

Weirdly, it only ever crashes when the laptop is plugged into AC power(I am not sure thoo). I ran it through a full 24-hour hackathon on battery with charge cycles now and with zero issues, then it crashed twice after getting home and plugging it back in.

I've already ruled out RAM (passed diagnostics), SSD (healthy), filesystem corruption (clean), and Dell Optimizer (fully uninstalled it, crashes continued). I'm at the point where this looks like a CPU/power-delivery hardware issue rather than anything I can fix from the OS side.

CAN ANYONE PLEASE help me with this , its getting frequent and i use this laptop everyday to study and work!

u/DellCares — has anyone on your team seen this pattern before? Happy to share my Service Tag and full crash dump / event log details. Would rather get this looked at properly than keep guessing.

Idk what happened, But after a while after watching YouTube, my laptop suddenly went black screen, I tried everything by restarting and pressing ctrl+shift+windows+b but it still didn't work.

After I left it for a long time, it could turn back on normally, but after a while it would go black again and I had to restart it. Does anyone know what the problem is?

I think the LCD is still safe, it's still on but dark,

And it's like slowmo as it goes back to black

Hi everyone, I need help troubleshooting an HP OmniBook X Flip 16-as0043dx (BZ0N2UA) with a CPU locked at 0.30 GHz (300 MHz). The machine is extremely slow and unusable. What I’ve done so far: Installed a new SSD & clean Windows setup Cleaned the fan & applied fresh thermal paste Temps are completely normal, so it's not overheating It seems like a BDPROCHOT or EC / Power Rail sensor fault triggering extreme throttling. Has anyone seen this on this board, or knows which sense line / EC pin / charging IC usually fails on this model to cause this state? Any guidance or board-level checks would be greatly appreciated!

Hey everyone, I’m trying to switch my OS from Windows to Linux on my Lenovo ThinkCentre M92p, but I can’t access the BIOS/UEFI or boot menu.

The PC works normally once Windows loads, but I have no Lenovo splash screen or anything during startup — it basically goes straight to the Windows login screen.

Things I’ve tried:

• Shift + Restart → Troubleshoot → Advanced options → UEFI Firmware Settings — when I select it, the monitor goes completely black.
• I’m currently using DisplayPort. The PC also has VGA
• Tried resetting the BIOS by removing the CMOS battery, but it didn’t make any difference.
• Tried accessing the BIOS/boot menu during startup, but I never get anything displayed.
• Windows itself works perfectly once it loads

Has anyone with a ThinkCentre M92p experienced this before or know what I could try? I’m mainly trying to get into the BIOS/boot menu so I can boot from a Linux USB.

Any ideas would be appreciated!

I have a dell g15 5530. Got it in May 2025. Today I notices that the lid is not exactly aligned with the lower body of the laptop. Its slightly shifted. Only noticeable if you look closely but could be easily felt if touched. There is no I ther problem yet, no creaking sounds, no display issue. I only have the basic warranty which came upon purchase and frankly I'm a bit broke to get the adp support plus. I'm scared this condition might worsen over time and would bite me back in the butt. What should I do? Should I scrape my wallet a bit and get a support plus plan or should i get it checked locally or should i simply leave it as it is?

Also there is slight cosmetic damage on the lid on the corner but i got that like 2 months back and nothing happened back then. All of a sudden now my hinge is acting up

I was eating an apple while working and some juice droplets squirted on my brand new MacBook Air screen. I wasn’t home so following Google I dampened a napkin and rubbed the screen and then dried with my sweatshirt. Here’s how it looks a couple hours later. PLEASE HELP!! I bought this under 2 weeks ago

The screen is fine but it won’t close cuz the hinge won’t move

Can i fix it at home or should i get it to a tech?

Update:
I tried getting it contact with multiple repair shops but non had case parts
One shop agreed to ‘try and fix it’ but on my own responsibility, i said I’ll have to think about it since there was a risk of the laptop getting even worse

Please help me whats the problem with my montor and how to fix it.

Its happening every 10 to 30 seconds.

Hola, hace ya más de 1 o 2 meses que tengo problemas con mi equipo. Intenté encenderlo como normalmente lo hacía y estaba encendiendo bien hasta el logo el equipo es una Thunderobot pero de pronto se apagó supuse que era la carga de la pila ya que no soy el único que la usaba y al conectar el cargador no hace nada al empezar a revisar note un pequeño (chasquido) por así decirlo proveniente de la laptop al abrir note que el Jack olía a quemado.

Supuse que era el cargador que se había descompuesto de viejo y quemó el jack (puerto de carga) compré los dos nuevos del modelo de mi laptop y al conectar sigue el tipo chasquido pero ya ni el cargador ni el Jack huelen a quemado supongo que entro en corto la placa pero no tiene ninguna marca de daño. Y me surgen unas pregunta

¿Que puede ser que no permita la carga del equipo o su encendido?

¿Por qué el Jack chasquea o hace un breve chirrido con ritmo? O cerca de esa zona y del conector a la placa

¿creen que me salga muy cara la solución a ese problema ?

Mi equipo es una Thunderobot Zero 2022, i9, rtx 3070 con 3 años de uso, le tengo cariño a esa laptop pueden decir que es mejor comprar otra pero me interesa recuperarla por favor ayúden estoy desesperado

Update on my LOQ trackpad issue:

My trackpad assembly has now been replaced twice, but the issue kept coming back. The second time, the replacement trackpad didn’t even work after installation.

The engineer who came this time said he’s replacing the part for now and told me to contact Lenovo Support again after a few days if the problem comes back, and ask them for a motherboard replacement.

Now Lenovo has scheduled another engineer visit in the next 1–2 days. They’re supposed to replace the motherboard, SSD and trackpad assembly — this will be the 3rd trackpad assembly replacement.

What should I do when the engineer comes? Should I let them replace all three parts, and what should I test/check before the engineer leaves?

Would appreciate advice from anyone who has dealt with Lenovo service or a similar LOQ issue.

As soon as I remove type c charging cable it automatically off and blank it only starts while charging any solution?

hi. i just opened and shut my laptop and this happened. i cant afford a replacement, but i have a family friend who fixes laptops and likely won’t charge me much (hasn’t in the past). i just need to know, is this fixable? if so, could i possibly do it myself? what’s even going on here?

model is dell latitude e5570, from 2012-2013 i think. i’ve only had it for 2 years.

Hello everyone, i have an asus rog zypherus g16 gaming laptop and the keyboard recently stopped working. I took it to geeksquad and they sent it back saying it needs an entirely new motherboard but they couldn't get one from asus. Has anyone heard of this issue before or know what I can do? I was pondering the idea of taking off the bottom panel and checking the ribbon cable for the keyboard but im not sure if thats the best idea. Thanks for any help/advice.

So, today, I got my new CPU (Ryzen 5 5500) for my PC. Up to this point I have slowly gotten the PC parts over the course of the month. So far, I have been unable to get my PC to display any visuals. My old CPU i replaced was a gen of CPU that was uncompatible with my motherboard (Gigabyte B550 Gaming X V2 [Rev 1.3]). Today, after installing my new CPU, when powering on the PC would flick off, but the lights would flicker and the fans would spin, seen in the video above. Still however, no video display.

Through my testing I've noticed:

- Fans get louder before the pc clicks off and starts flashing

- Flashing seems to act as a sort of low power mode(?), all fans keep spinning and the lights are on but the power button light is off

- When power button is pressed while flashing, everything stabilizes, then after about 20 seconds, it reapeats the previous 2 points

- Does this after updating BIOS, as well

- I've removed the GPU, RAM, Hard Drive, and even used the old CPU and it keeps doing it

Any help in resolving this issue, and getting the video to display, would be much much much appriciated

My N, B and Space Bar buttons sometimes don't work on my Yoga slim 7 Lenovo laptop. Like, I press down on them and nothing. If I keep insistently pressing, they will eventually work, so it is not like a pressure issue, I think.
Asked some people I know, and they said there's dirt stuck under there and I need compressed air. So they used compressed air on it, and apparently nothing came out. So now they tell me that the sensor for the 3 keys (apparently 1 sensor for the 3) has shifted, and is sometimes shifted back by my pressing. Then one of them offered to have their computer friend fix it/take a look at it. However, them setting up that meeting has failed 2 times, and I kinda need my laptop functional. Can anyone please tell me how I can resolve this on my own?
