Hi everyone, I've been having some laptops coming in [Toshiba , Hp , Lenovo] with a peculiar problem of power cutting off approximately 30mins, whether the laptop is booted into windows or without an hdd installed or whether on battery or adapter or both. There are no signs of heating and the motherboards are clean. I wonder if anyone has experienced this issue.

If these laptops on Intel - than you should know which PCH (chipset) is installed - HM55/65
Also you should write models of laptops.
