Question Black screen , no boot, but only when restarting the laptop ?

[legion5ipro]

Laptop Model: Lenovo Legion 5i Pro 16ITH6H
CPU: i7-11800H
GPU: RTX 3060

Laptop is about 3 years old and is out of warranty

I have a very strange issue.
It happened when I installed the latest nvidia geforce game driver about a week ago.( don t think it's related to the issue)

When I finished the install I had to restart the laptop. After restarting I got black screen , and no way of booting.
Holding down power button for 60 sec, turning it on.. after about 100 times it finally boots.

And this problem persists even today. And ONLY when I restart the laptop . Weather manually or on a update
If I shut it down normally it will boot up just fine when I power it on. But when I restart it it will black screen no boot
Keyboard flashes and lid backlight is glowing, but it will not boot. I can hear the fans a bit and it will be black untill a lot of resets.

Here's what I've tried :

• Connecting the external monitor
• Reinstalling windows
• Installed different drivers
• Tried switching each ram In different slots, and running them one by one
• Tried booting without ssd
• Tried cleaning the fans etc
• Disconnecting/ reconnecting battery

The issue is always the same. Black screen and it does not boot up , every time I restart it I have to hold the power
Like at least 100 times until it finally actually boots up without black screen.
And sometimes before it actually boots "restoring bios to factory" settings pops up . But that might just be because I held power button so many times

Very strange that it boots normally when clicking shutdown, but clicking restart basically kills a laptop until some random occurence manages to boot it.

Tried booting without ssd

This indicates hardware fault (POST stalling), whereby possible culprits are: CPU, MoBo, RAM, GPU and/or PSU (power brick).
What further proves it, is the clean Win install you did, since that gets rid of software issues.

Laptop is about 3 years old. And is out of warranty

Just because laptop is out of warranty, doesn't mean that you can't get it fixed. You still can, by hauling it to PC repair shop and paying for diagnostics + fix. But the downside is, that you have to foot the bill and not the manufacturer. Still, it is better to get it working normally than messing it with all the time, where at one point, it may become completely dead.

Either pay to fix it or buy a new laptop. Your call.


For repair shops, Northridge Fix is one of the better ones,

While Northridge Fix is USA based, they accept international shipping and can do repairs worldwide. (If you're located outside of USA.)

Alex, founder and owner of Northridge Fix, often posts electronics repair videos to his Youtube channel, that i find interesting and informative to watch.

They also sell all and every kind of equipment to do with electronics fixes. Soldering stations, microscopes, flux, capacitors, mosfets, connectors etc.

I gave it to repair shop , they said they couldn't turn it on and capicitors were burned. When they were cleaning it they said "leg" of bios chip fell of and i would need to replace a whole mb

and capicitors were burned.

Caps usually burn out due to high temps. With laptop and when there's restricted airflow and/or no dust cleaning, internals will heat up.
That's most likely possibility. Though, caps can die on their own (manufacturing error) but it is usually 1 cap, and not several at once.

"leg" of bios chip fell of and i would need to replace a whole mb

BIOS chip usually has 6-8 solder points (or legs when solder point is outside of the chip). So, when one falls off, the chip isn't toast. The leg can be re-soldered back.

Here's collection of BIOS chips:

I guess the repair shop doesn't have the equipment or know-how to re-solder the broken leg. 🤔
Alex (Northridge Fix) knows how to re-solder the broken leg back. I've seen him do it countless of times in his repair videos.

Thanks. I will try taking it to someone else( not Alex (Northridge Fix) ) because I'm from EU .
Maybe an actual professional this time. Unless you recommend someone from EU ?

Well, i'm at EU myself, but when need be, i'd ship my stuff across the pond for Alex to work on. Since for Alex, i can personally validate his expertise (thanks to the in-depth videos he makes of electronics repairs).
For other shops, i have 0 clue on how competent they are, since anyone can advertise that they are the best in the area.

Now, in my local area, i know of one shop who does good mobile phone repairs. But mobile phones are different from laptops/GPUs and i'm not sure that they have the knowledge regarding PC electronics.

As for as Alex goes, he has repaired stuff sent to him from India and even from South Africa.
E.g here's the vid with shipping from South Africa, short circuited laptop MoBo btw:
