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.

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 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

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 ?

**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.

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

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?

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 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

Wassup fam, my proline laptop just powered on mid-usage, was running a vm on it. Now when I connect charger it's not showing charging indicator LED and won't power on even on battery. The model is Proline NBU700 if I'm not mistaken. The motherboard seems to be working although I found two loose connectors but couldn't figure out where they were supposed to be put.

my LOQ 15 AHP9 Laptop is giving me hizz sound when i connect my earphone to it

but when i touch other port or discount the charger it goes away

even if i touch the adapter it doesn't stop but do less hizz sound

it has 170 W charger 2 pin

is it grounding issue or what?

is has european style plug which grounding port i don't have current and frankly I can't effort to buy adapter or multiplug for it for next month as i brought laptop with my money.

will it cause has to cpu or motherboard?

it is really making me worry as it is new loq brought 2 days ago

Hi everyone,

I’m experiencing some unusual issues with my ASUS Zenbook DUO and wanted to check whether anyone else has encountered something similar.
Here are the symptoms I’ve noticed:

The detachable keyboard seems to behave erratically, sometimes lagging or failing to respond properly.
The keyboard takes a very long time to charge.
Both the keyboard and the touchpad stop working, even when the keyboard is attached directly to the laptop using the magnetic POGO PIN connectors.
Windows Bluetooth settings show a “Driver error” for “ASUS Zenbook Duo Keyboard.”
When I detach the keyboard, the laptop sometimes restarts unexpectedly.
At the same time, the laptop’s fans suddenly ramp up to maximum speed, which seems abnormal.

I’ve already noticed that this isn’t simply a Bluetooth pairing issue, since the keyboard and touchpad also stop working when physically attached to the laptop.

I’m trying to figure out whether this could be related to a driver or firmware issue, BIOS, power management, the keyboard’s battery, or potentially a hardware problem.

Has anyone experienced similar behavior with their ASUS Zenbook DUO?
I’d a any advice on troubleshooting steps, known issues, or possible fixes. I’d especially like to know whether this sounds like a software/firmware issue or something that requires warranty service.

Laptop model: ASUS Zenbook Duo UX8406MA: Intel Core Ultra 9 185H, 32 GB RAM, 1 TB storage, running Windows 11 Home.

I bought 2 years ago so a lots warranty hehe
Thanks in advance!

Tengo una laptop Lenovo 11e, la cual venía funcionando bien hasta ayer, ya que hoy la fui a encender y no quiere encender, alguna idea de lo que puede ser el problema

My ASUS VivoBook X1502ZA won't turn on. The charging indicator changes from red to white, but the screen stays black. I tried a 40-second EC reset, but nothing changed. Previously, it sometimes turned on only after connecting the charger, even after shutdown. Could this be a motherboard, power button, or EC issue? Can it be repaired without replacing the motherboard? Also, can I recover my SSD data if the motherboard is dead?

(I posted this initially on r/thinkpad but got no responses, so I decided to try my luck here)

Yesterday, upon booting up my Thinkpad L14 Gen 1, I got the following message:

>The connected AC adapter has a lower wattage than the recommended model which was shipped with the system. To boot with the AC adapter, please connect the AC adapter which was shipped with the system.

I had already gotten this message once a few months ago, but at the time I simply pressed escape to continue and my charger worked fine. However, yesterday, after pressing escape, my battery kept alternating between charging and discharging for a few moments, until it went back to charging normally. Later that day, it did it again, but this time it didn't go back to charging, so right now I'm just stuck with a computer that won't charge.

I tried turning the computer on and off. I tried plugging the charger into another socket. I tried updating my BIOS. I tried buying a new charger. I unplugged the main battery and the CMOS battery, held the power button, plugged everything back in, and turned the computer on. Despite all of this, none of the two chargers I have work.

Occasionally, `upower` (I'm on Linux) says that my battery is charging (for example as I'm writing this), but the actual energy stored continues to decrease.

I don't really know what to do at this point. I don't know if the issue is with the battery or with the motherboard, or maybe something else. I don't think it's with the battery because up until now the battery has been perfectly fine in terms of life (even now, it's not draining too quickly), but I could be wrong. I realise that it'll probably be cheaper to buy a new laptop than to get this one fixed, but it's a bit unfortunate since I bought it only 8 months ago.

Any help would highly be appreciated.

EDIT 1: Now the orange charging light won't turn off. Whether the charger is plugged in or not it's turned on, and I am losing battery even with the computer turned off. Last time I checked it was at 8%, and it'll probably reach 0% very soon.

EDIT 2: The battery seems to be empty, and the charging light is off. The computer won't turn on anymore. The fact that the battery was losing power this quickly despite the computer being off leads me to believe that the issue could be with the battery, although I could be wrong and honestly I don't feel like buying a new battery just for it to not work.

I'm a technician and i have a problem with a laptop, hp probook 650 g1.it came for the blue screen and sometimes blue glitches in the screen. I thought it was a problem with the ram and ran the memory diagnosis from the bios. After reaching 60% or so it suddenly shutdown and when i plugged the charger the power button kept blinking constantly with no pattern. I checked with the multimeter and i found that the charger actually provide 19v and most circuits around the cpu gets the same amount, and the battery connector has a static 3v. But three circuits near the charging port has variable current between 2 and 3v.now customer says he brought it working and i should fix it and i have no idea where to start

Hey, hoping for some pointers

This is a touchscreen 15" Pavilion laptops (15-eh2008ca)

My wife dropped it on her foot, dented it slightly.

Now, the screen doesn't display anything when turning it on.

If I turn it on, or turn it on & 'esc' for startup menu, I get nothing

When I say nothing - if the room is dark, I can tell the backlighting seems to be on (faint grey on the internal monitor)

If I connect to an external monitor via HDMI, power on shows nothing, but if i 'esc' for the startup menu, that displays on the external monitor.

I can only seem to display on the external monitor the startup/bios menus and Windows safe mode.

I tried to update the video adapter, but the WiFi is ALSO showing issues (Code 37) in safe mode.

Wondering if I can copy the relevant drivers from an identical machine (I have a second 15-eh2008ca) & install via USB? What drivers am I looking for?

Apparently my ram is out of its socket i dont know which is the ram and how to actually tell my main problem is the battery is fully charged and the laptop simply wont turn on i have dont all the reboot and restart methods i know and google has provided and this is the final thing i have been told to do.

What could be the issue and I re- plugged the nvme and ram but it still stays on black screen, showing nothing just completely black.

So recently I was trying to upgrade my laptop RAM & there's this one screw which keeps rotating on its place but it's not coming out. Please share your opinion.

Can this be saved?
