Random refusal to boot, but works when taking out and reinserting RAM?
Alright so: My friend has a Lenovo Loq 15ARP9, purchased around a year and a half ago. It's been working fine, save for some random issues with the camera not working. Nonethelss, it's been working just fine and dandy up until recently. However, there's been a new development:
The laptop boots into a pure blackscren, but the keyboard still lights up. I've instructed him to:
- Try using a secondary monitor, no display;
- Press F2 or F12 during boot, no sound;
- Hard reboot, no effect*.
*Currently trying this again, will update with result once done
After some tinkering, I asked him to try taking out a stick of ram to see if that was the issue. He did, and it worked. But then we started testing each stick in each slot, and they all worked just fine? And afterwards, when he put each stick back into their original slots, the laptop still booted up just fine? Anyway, the laptop worked just fine afterwards for a few weeks. Current issue is: It happened again.
I frankly don't know what to advise him to do and I haven't really seen this problem on other forums, so I just want to know if anybody else has any other thoughts on this? He is a frequent mover, so it's possible that it's a loose stick of ram/connection/socket, but I really don't know.
How could I help him in this situation, and do y'all know what could be wrong?
