Hoping someone can help with this. I have a Legion 5 - ryzen chip and 3070 gfx, yesterday i shut the laptop down as normal and today it wont boot up. The charging light comes on when plugged in, as doe the the power led when i press the power button, but the screen is completely blank. Occasionally it will boot to windows - maybe 1 in 30 times. Same for bios but otherwise it just stays blank

I have tried a fresh reinstall of windows, checking each stick of ram individaully in both slots, battery unplugged, swapping ssds and nothing makes a difference.

It's maybe 3 years old, out of warranty and I really dont want to buy a new one so hoping someone has had this before.

Any ideas?
 
What's the betting it's the bios chip? My guess is it probably has a winbond SPINOR bios chip that's giving up the ghost.

Thing is, I can occasionally get into the bios.

I'm accepting that this thing is toast. Contacted Lenovo CS and bizarrely they are allowing me to purchase the warranty that would in theory cover the repair of this. Even though the laptop is 2 years outside of original warranty for like £100. Has to be a catch somewhere but if true seems a no brainer. I'll try and actually speak to someone tomorrow

On the warranty point I wonder if its like any form of insurance. Yes you can take it out but, anything already an issue would not be covered.

Yeah it is. For existing faults they reserve the right to charge. But... I don't see how they'd know it was an existing fault?
 
Ok, so I'm pretty sure it's heat related. When the laptop has been off for a few hours it boots reliably. Ran a few stress tests and sure enough it fails to boot.

Is it worth repeating the GPU and CPU? If so what kind of paste would I use? Never done anything like that before

Being out of warranty, repasting has got to be worth a go.

I'd be looking at Thermal Grizzly for paste.

I've used Arctic Silver in the past as well, with success.

And, if you do go for repasting, it's worth fumbling through Lenovo's web site to find the hardware maintenance manual for your model.

Yeah I'll give it a good clean out whist I have it apart.

I think Lenovo use a phase change material. Am I ok to use some thermal paste? Or do I need the same stuff as came on the laptop?

Thermal paste should be OK.

Not like it's not reversible.

Well, I gave it a go. Sure enough the laptop booted up, ran a few stress tests and both CPU and GPU temps were fine. Shut it off, tried to restart and nothing. Same issue.

I've read the solder under these CPUs in the legion laptops keep failing and the CPU will need reballing.

Cant seem to find anyone who does this type of work and I'm guessing it wouldn't be worth it either from a cost pov.

Really annoyed, won't be buying a Lenovo anytime soon
