So i just got this used laptop FUJITSU LIFEBOOK AH502 I3-3310M With 4 gbs of ram and it always shut down at exactly 30 minutes i tried the following i also tried with a different laptop battery
1-Reformat the hard drive fresh os Windows 10
2- Reset bios settings
3- Install new cmos battery
4-Reset bios settings to default
5- Update every possible driver bios ect
6- Suspend Intel AT something on bios
after i did the 6th step somehow it got extended at 40 minutes but it still lshut down next time also shut down at 30 minutes
And its not a heat problem cuz i monitored the temperatures and they were more than normal and the fan and everything else is really clean
