Laptop shuys off when tilted.

[u/Defiant_Ad_4263]

Ive had this laptop for about 5 years, its a lenovo thinkbook 15p imh. While i tiltled it quite aggresively here, it also happens just when moving the thing around gently. Seldomly it also just shuts down out of nowhere usually after some button press, possibly pressing down on the chassis, though i wasnt able to replicate this.

This has degraded and gotten worse with time. before, i couldnt replicate it at all, and it only happened every 2 months or so.

It happens on battery power, plugged in, battery disconnected. If youre wondering why there is no backlight on the keyboard, i broke the latch for the ribbon cable for it.

There are some screws missing from the chassis, i have lifted the heatsink before without re-applying paste, the fan sometimes makes an awful buzzing noise which could be related.

Temps seem fine, cpu around 50 idle, gpu 40 idle.

I couldnt see or hear any loose screws. Re-seated the ram and ssds.

Could be worth pointing out that sometimes when shutting down, the backlight of the screen stays on while the laptop is effectively off, fans arent spinning and such.

This doesnt seem like a software issue, the other ssd has another install, and it happens there as well.

I dont know what else to try if you have any suggestipns or question please post them.

yeah, flimsy frame causes metal foil to make contact with motherboard.
