Acer Aspire E1-531: Shutdown in 30 min

[DeathBringer]

Your laptop is based on HM70 chipset. This chipset has well known problem and can't run i3/i5/i7 more then 30 minutes.
It can't be solved by BIOS patch. Only hub replacing will help. Or you can replace whole motherboard to new one with HM75, HM76 or HM77.
Another solution: put your laptop to sleep state every 25-29 min. This reset a timer. You can use Task Scheduler to do it.

OK DeathBringer....

i don´t know how to patch the BIOS.....

If I send BIOS file, can you patch it for me?

I repeat: it can't be solved by BIOS patch.

I'm just throwing in my two cents: 30 minute lockdown is probably some sort of "corporative" fence to avoid upgrade on lower end chipsets.
It may be related to Intel ME (that is a machine / operating system running INSIDE your chipset).
That 30min "grace time" is consistent with Intel ME "anti tampering" countermeasures (you broke ME : the board will shut down after 30 min).
There's a way to partially disable IME (having it "off" after boot) that could, maybe, fix this and other problems... but it's complex and requires a TSOP flasher.

I'll leave this here, maybe it's a new path.
