My trusty old thinkpad isn’t very well and I’ve not been able to solve it so far
Every time I turn it on, 9/10 times it gets stuck in a loop where the power button comes on, screen lights up blank briefly, and then it powers off for a second before coming on and powering down again.
Very occasionally it will start up normally
It’s a pretty old machine now but it works well enough for me, is there anything I can try? I have tried a different power supply and resetting the BIOS settings to default but the issue still happens
