Why can the bios on a laptop regularly fly off?

Question

laptops

There is a samsung q35, the bios did not boot. I found how to reflash it from a flash drive. Immediately after flashing the BIOS, it starts up and the laptop behaves normally. But as soon as he lies down from a day to a week, the bios again flies when turned on. What could be the problem?

Answer 1

1. The flash drive itself dies - I saw such a problem just on Samsung, though on the R-series. You write one thing with a programmer - another is read, and all sorts of crap.
2. Buggy BIOS
3. Internal battery - depending on how it flies. If CMOS and clock - then it's a battery.
