Hibernate laptop powers off after unplugging power

[chico_001]

Hello,

I put my Windows 7 laptop to hibernate when it is plugged to the power source. When I unplugged the laptop from the power source, the laptop powers off. The next time I turn on the laptop, it is restarted and I see the screen with a message that says Windows was not properly shut down.

Has anyone seen this before?

Battery could be either too low a charge to power the laptop, or battery may have come to the end of it's usable life and needs replacing.

The latter is the most likely explanation if you regularly use your laptop from mains power for long periods without removing the battery to prevent it being overcharged - this shortens it's life.

if it not the battery then it can be the ac brick not outputting the right voltage to recharge the battery. msot times the battery is at the end of it life.

I don't think it's the battery. I was running on battery for 2 hours before it needed a recharge. Why would a hibernated laptop with a fully charged battery shut off when the power is unplugged?
