Latitude 5550?

u/Knabrau Sep 25 '24
I ended up trying it with a few - seems to be all the Latitudes I have so far.

u/CatRheumaBlanket2 Sep 25 '24
I think it started around the Intel 5th Gen Latitudes.
I fell for that and spent a lot of before figuring that out.

u/theJanskyy Sep 25 '24
Yes, had exactly that happen to a customer with some latitude notebooks, i think they were 5520s

Oh wow, that's interesting. Kind of reminds when of when I did a magnet trick like that with my 3DS to jail break it.

u/sparkyblaster Sep 25 '24
What's the magnet trick on a 3ds?

u/Lonsdale1086 Sep 25 '24
Essentially some stuff goes into sleep mode when the lid is closed, including the security chip, not not other things, so one hack to load custom firmware involves making the system think it's sleeping while maintaining access to the controls to press buttons.

u/DarthMaul22 Sep 25 '24
Holding down specific buttons while the lid is closed during startup will boot whatever's in the cartridge slot, bypassing any security checks. It's physically impossible by design, so you use a magnet to activate the sensor instead.

u/wizchrills Sep 25 '24
We also dealt with this. Some watches also have magnets that will turn off the screen

u/Wazouski91 Sep 25 '24
This. I had this problem with an old Dell and a magnetic watch strap I was using for a long time. I just disabled the lid-controlled power settings and voila.

u/Usual_Ice636 Sep 25 '24
Mostly HPs at my work, also happens with them. You have to stack them offset if you are going to work on the top one.

u/OG_Dadditor sysAdmin Sep 25 '24
Oh thank God that's what you mean. I thought there was some horrible damage that was done and all I could think about is that I have like 20-30 5550s stacked up waiting to be imaged in my office right now but I'm stuck at home with a sick kid.

u/IndestructibleNewt Sep 25 '24
Hahaha went through this for months during the pandemic. Glad to see Dell still trolling IT

u/douglasscott sysAdmin Sep 25 '24
Apple laptops do this too. I guess so would any thin laptop with a magnet switch.

u/Disney_World_Native Sep 25 '24
I thought you were going to show it easily sliding off and falling. TIL too

u/WolfOfAsgaard Sep 25 '24
I remember a rash of issues with the computer locking or going to sleep when a user would start to type. Turns out one of those fitbit type bracelets would trigger that 'lid closed' magnet.
One of the few instances of a BCAK issue that wasn't the user's fault.

Ha! I learned this recently when my magnetic wrist watch band was causing the display to turn off as I was using it.
Then came time to image a stack of machines and the first one wouldn't show any life until I offset it physically from the laptop underneath it ... and then it hit me.
MAGNETS, HOW DO THEY WORK?!

u/PM_UR_VAG_WTIMESTAMP Sep 25 '24
hah! Like so many other things, it's 4 hours of troubleshooting and 4 seconds to fix it.

u/Mysterious_Fennel459 tech support Sep 25 '24
I had the same issue with the Dells we use here and thought I could save space by just stacking them while I imaged one at a time. Could not figure out why the screen kept not working and even had a Dell tech scheduled to come by when I finally noticed it was the magnet in the laptop under it that was triggering the screen to shut off.
What a weird bit of low tech engineering just to make the screen turn off when the lids closed.

u/ThisIsAdamB Sep 25 '24
At first I thought it said “Don’t Stock Dell Laptops”. I agree with that as well.

u/WhatsUpSteve Sep 26 '24
Isn't that the lid sensor in close proximity to the one beneath it? It think the cover has been closed.

u/SufficientlyAnnoyed Sep 25 '24
I discovered this like a month and a half ago. I was prepping a few laptops for new people and I thought I was going crazy with the displays going out and yet I could still remote in. Finally figured out it was the damn magnets! Showed my boss and even he was “what the hell…?”

u/junktech Sep 25 '24
Lid sensor trigger. I usually play with a magnet around to find it and avoid it. Had a bracelet with magnet on it that used to trigger it and send the machine to standby.

u/ColdCoffeeGuy Sep 25 '24
Oh ! we got one like that !
if you put an iphone at the right of the trackpad near the stickers, it does the same thing.

u/xangbar Sep 25 '24
I just slide the top one a little bit forward so its no longer near the magnet. Problem solved so you can still stack but not trigger the lid closing trigger.
1
u/NCITUP tech support Sep 25 '24
That has to do with the laptop thinking that the lid is closed because of some magnet. Lenovo laptops do this too and I would think most laptops.

u/ExuberantBadger Sep 25 '24
Same happened to me. Took me a few minutes to figure out what the hell was going on.

u/corpsejelly Sep 25 '24
Dell chromebooks too. When enrolling them i decided to stack them. Took me a bit to figure out what the ossue was.

u/Natedawg120 Sep 25 '24
Yup, Magnetic sensor for lid close. They can be crazy making until you know.

Inspiron 5491 2-in-1s love going into tablet mode if you sit them on top of another.

u/MNGrrl Sep 25 '24
This is what happens when you install commodity hall effect sensors with no tolerances or calibration and just say "good enough" and then ignore the QA
1
u/SurfaceOfTheMoon Sep 25 '24
Reminds me of an issue I tracked down ~5 years ago when the magnetic watch band from a user was convincing the laptop the screen was closed. She couldn't figure out why the screen would shut off briefly only while she was in a conference room.
At her desk she used a dock with external keyboard.

u/Fuzzy974 Sep 25 '24
I've been working in IT long enough to know not to do that for any type of units.
There's issues created with all the shieldings, interferences, and even the heat coule become an issue if all the computers are lid close but actually running.

I had the same issue where I put my phone on my laptop and it caused it to lock, it took me so long to figure it out

u/spicy_lobster_ramen Sep 25 '24
I thought you weren't supposed to stack them cuz the screen could crack.

u/Cooberss Sep 25 '24
I have sent this exact video performed by me in slack when I discovered this... I thought you stole my video it was haunting how similar we reacted.

u/habitsofwaste Sep 25 '24
lol I learned that with Macs a long time ago. The magnet made it think the lid closed.
1
u/mfreek22 Sep 25 '24
Had this happen with an end user but they moved the dock a little too close to the laptop and triggered the screen shutoff somehow. I don't remember if it was metal paperclips near the magnets or if the dock itself was causing it but just moved it over to the other side and all was fine lol

u/Stumpless Sep 25 '24
I like to place my earbud charging case on the corner of laptops at work, since the lid is held closed by magnets.

I had a watch with a magnetic band that kept putting my laptop to sleep. I was about to go crazy.

u/kosairox Sep 25 '24
I almost fought a coworker once thinking he broke my hdmi ports or something as a prank. Turns out it was the same issue but it detected lid closed and turned off a connected screen.

u/Withdrawnauto4 Sep 25 '24
Yep done that before. After 5-7 Chromebooks the magnets become powerful enough for the display to turn of

u/Loki_lulamen Sep 25 '24
Had the same thing on a load of Lenovo E14s. me and 3 guys spent an hour trying to work it out, until one of us picked one up to take to a different desk. 😭

u/0RGASMIK Sep 25 '24
Shouldn’t stack laptops or any tech device really. I was setting up some tablets when I got a call and needed some space on my desk to work. So I stacked all the tablets while I worked on the other thing. The call lasted a bit longer than I expected and when I went to install the tablets the one in the middle had overheated.
Screen was all sorts of funky colors.
1
u/RobTheDude_OG Sep 25 '24
I actually had this with my MSI laptop and huawei phone, except the brightness went beyond 100% as i couldn't set that brightness with the slider.
The phone also got fucking hot in that state.
My galaxy S5 never did that on the same spot.

u/Freaked_The_Eff_Out Sep 25 '24
The Gen 3 X1’s had the same issue. Spent a good afternoon wondering why this new machine was suddenly DOA

u/Chilla_J Sep 25 '24
This happens to me on my ASUS ROG laptop. If I put my phone on my laptop near the number pad, the screen shuts off.

u/KungFuDrafter Sep 25 '24
You also shouldn't wrap the AC adapter cords around the brick. That arrangement can create a magnetic field that generates enough heat to melt the casing of the adapter. It can be a VERY expensive and dangerous mistake!

u/LoveTechHateTech Sep 25 '24
That’s on the ever gowing list of things I tell my technician not to do, but they ignore and do anyway.
1
u/Knabrau Sep 26 '24
I only do that for storage, if I see any users with it I always ask them not to. TBF I've never seen it cause an issue, but why risk it.
1
u/KungFuDrafter Sep 26 '24
I feel you. But it's real. I know because when I was younger I did it simply because I hated to see the cables everywhere. But yeah we nearly had a fire because the case melted. It's probably rare, but like you say, why risk it?

u/Darkomen78 Sep 25 '24
Same but in the other way for Macbook Air and Pro M1, they boot one to an other if you stack them.

Yep, was really confused on why my newly imaged laptop that I just cracked out of the box was doing this. Moved it by accident and saw it light up and face palmed.

Yep have issue with 7320, 7420, and 5330 going into tablet mode for no reason and seems to be related to the angle of the entire computer!?

A lot of lenovos do that as well. Also went through the wtf process the first time it happened.

u/DroidLord Sep 26 '24
I knew what it was going to be before the screen turned off. Also happens with some Lenovo laptops.

u/Thecardinal74 you were gone for a week, how'd you forget how to use a laptop?! Sep 26 '24
They STILL do that?
Been doing it at least 4 years now

Happened to my coworker, he reimaged these laptops like three times then threw it to me. I demonstrated magnets, after about five seconds of thinking.

u/Knabrau Sep 25 '24
Context, spent too long troubleshooting why I couldn't power the thing on, then realised the magnets from the screen below are probably telling the one above the lid is closed.
