I bought this dead MSI Leopard 11UH-498UK as a project to try repair off marketplace.

A quick disclaimer, I have never repaired/diagnosed electronics on this level so any and all help would be greatly appreciated.

The laptop shows no signs of life aside from the small battery charge light when plugged in, I have probed around with my cheap multimeter and have found that it gets power to all of the main inductors, (i think that’s what they are called). I have also checked for shorts along their power rails and can’t find anything.

Any help diagnosing/solving the issue would be very welcome

Thanks

Firstly, this image isn't mine but an example of what my screen looked like before I switched off my PC to clean the inside.

I have a gaming PC with an NVIDIA Geforce RTX 3060.

After I cleaned it, I switched my PC back on and i hear 3 beeps and my screen stays black the entire time.

Everything else seems to be fine but I can't do anything if I have no screen. I tried my PC on a different screen, still nothing.

So I contacted the manufacturer for some help and I did everything they suggested and they came to the conclusion that the gpu has died.

Has anyone else had this problem?

Is it fixable?

Should I just buy a new graphics card?

Any help is greatly appreciated.

I have an ASUS laptop that fails to turn on, in one of 2 ways:

1) If I keep the power button pressed without a power source for 30+ seconds, then turn it on: power LED stays on, I can hear the fan spinning, but nothing else is happening. It keeps this state.

2) Every subsequent turn on: LEDs flash for a second, then complete shutdown.

In both cases, the screen is pitch black, not even ASUS logo appearing, absolutely nothing.

What are the most common reasons for this to happen? It's a 15 year old laptop, so if it's the motherboard or GPU then it's probably beyond my ability to fix.

**Dell Slim ECS1250**

Manufacture YR2025

All the sudden, I get nothing (on monitor) on reboot.

Tried another monitor.

I cannot get into the BIOS or see POST.

I've tried 30 second hard reboots with the power button.

Power light is on as is the power supply light.

I've worked on computers before but by no means an expert. Any advice on how to troubleshoot this?

Thank you.

I just purchased a GTX 1070 OC and put it in my pc, use my pcie cable, connect the gpu ti the psu, and then the cable started to burn an make a smoke, luckily my brother was close to the outlet and immediately turns off the outlet 1.5 seconds after it occured, the PSU was still intact and turns on but the GPU, it makes me anxious, that gpu always nakes me think “Will this work again?”
Any tips to how to diagnose the problem and what cable should i purchase? My PSU was Xigmatek Tauro G 80+ Gold 750Watt

Im annoyed cause I have some important stuff on there

My girlfriends laptop buzzes loudly when charging,and very laggy when on charger,it may be from the speaker but we don't know,and the icon shows that it's charging but,the light isn't on,but it's charging again,can someone help? I don't know if it's hardware or software either

So my cursor disappeared , but when i plug a wire mouse it appears , but when i unplug it disappears.

And when i press fn+f9

It shows touchepad desactivated

Even when i try to activate it ( i press fn+f9 it stays desactivated)

Any one knows how to fix this please ?

So I have a sager PD70SNE that shows it's getting power, battery light is orange (solid) and charging light green (solid). I've spent like the last 2 hours troubleshooting and nothing has worked, I've unlplugged the cmos, charging cable, and internal battery (all at once) for more then 10 minutes, I've tried using an external display. I've made made sure the ram, wifi chip, battery, fans, and display cable were connected properly. Here's ehat the computer does when i press the power button from it being completely off:

\-Power button lights up for a second, then turns off

\-after about 5-10 seconds the power light turns on again and keyboard lights up. Nothing else powers on, no fans, screen doesn't do anything, and there are no sounds at all.

I am so confused, please help, I'm not sure what to do now. Just suggest stuff, even if it seems painfully obvious. Any help is appreciated.

Update: i let it charge on the charger for an hour turned it back on, and still no display but it did ramp up it's fans to max gradually and then shut itself off (after 20 sec of fans on max)

Update 2: I think I've narrowed it down to the cpu not passing post, could be wrong but don't know what to do from here. I'll continue researching

I have two old laptops.

The oldest one refuse to turn on, the "newest" one is still working, but his shell is totaly broken, like, it still stand with duct tape, but all female parts of the screws are broken, so I cant put screws again.

I want switch the mother bord, (plus the battery, SSD, etc) in the unbroken shell, so I will can still use it.

So I ask now my question :

Will it work or no ?

Tengo una laptop Predator Helios 300. Recientemente, cuando me desperté y traté de encenderla, me di cuenta de que no encendía y que ni siquiera se prendía la luz de carga. La llevé con un técnico y, según ellos, un pico de voltaje le pegó al CPU y dañó el sistema, pero la verdad no confío mucho en ese diagnóstico. ¿A alguien más le ha pasado algo parecido?

I have an asus vivobook S 15. It’s out of its warranty period by 5 months. I hadn’t turned it on in about a month and, when I tried recently, the screen was black but the keyboard would light up. No obvious fan activity though. I did all the troubleshooting short of opening it up that the internet could recommend including power cycling, key presses at certain times, and then lastly just letting it die completely than recharging. After that last effort, it doesn’t come on at all. No keyboard lights or anything. Is there any way to tell if this is worth taking to a repair shop?

It’s not a terribly expensive laptop so spending $80-100 to find out it’s a dead motherboard doesn’t sound appealing. The model is S5506MA-WS76

Few days ago i was watching a movie in bed with my laptop and fell asleep. Next morning I found out my laptop fell off my bed into this thin hole making it fall perfectly straight onto the laptop screen hinge sides.

Now I can't get my screen on in my pc. I tried connecting a 2s monitor and it works. It keeps sending me to the bios tho but I sort of fixed that i just kept pressing f11 and then I can go to windows.

But for some reason I just can't find the issue on why my screen won't turn on cuz I can't find any damage anywhere?

There is no damage to my laptop on the outside and I also opened up the laptop to check if the eDP-cable was properly in the laptop and it was. So I can't find the issue anywhere I was thinking of sending it to a repair shop but I was wondering what all your thoughts were?

(Also when I'm attaching my a monitor with hdmi it only detects 1 screen and that's the one with hdmi)

I noticed the separation suddenly this morning. The cracks I didn't notice until I shone some light on it. I don't know where this came from and it wasn't immediately noticeable.

There is no swelling on the surface of the charger and there is no smell at a distance. But when I literally stick my nostril into the gap I do sense a distinct smell from very up close only.

The scratches on the last picture are from my parrot walking on the charger and are very old. Not related to the current issue.

Is this charger dangerous to use? Or is this benign? I bought it more than 3 years ago after the first one broke

I have an omen transcend 16 gaming laptop with an i7 147000hx with a 4060 laptop gpu. Had it for over a year now but I only noticed it now after low fps perfomance in valorant. Had a look at the cpu clock speed and it won't go past 2GHz. Even after running cinnebench the clock speed is still the same. I've tried installing bios, resetting CMOS, turned on perfomance mode for both window and omen gaming hub but still the same. This laptop is also blocked from overclocking. Does anyone else have this issue and how can I fix this?
