My 3 year old HP 250 G4 laptop has started shutting down with no warning when on battery power. After consulting a few online help places, it seems as if it could be the battery or the HDD. HP's help utilities tell me that the battery is fine, and that the HDD is failing. Whilst I am happy to try a new HDD, I don't understand how the failing HDD only manifests itself when on battery power and never when plugged in to the power lead. For example, 2 nights ago, it died on me a few minutes after being unplugged from the power lead (power level at 98%), then worked fine for a couple of hours with the lead plugged in. After updating the BIOS, did a restart, unplugged it, and again, after a few minutes, it shut down. (These shut downs are literally that, ie screen goes black, machine is completely switched off, as if you had unplugged the power lead from a desktop PC. Then, on pressing power button to restart, it fails to load Windows properly, gives a repair option, but generally you have to tell it to restart, then loads Windows fine).
So I guess what I am asking is, is this the battery, or is it the HDD, and if the HDD, why doesn't it fail when on AC power?
