Battery power boot up problem

[Mark Fuller]

I have a hp pavilion dv4 with 4gb ram and windows vista and it won't boot under battery power even though when I boot it up with ac power it says the battery is fully charged.

How old is the HP? If its been a few years since you bought it, you might try re calibrating the battery from the BIOS, most HP and Gateway computers have a utility inside the BIOS for calibrating the battery. If not, let me know and I'll see if I can find one.

Thanx, I'll try and see and let you know.

I think the battery should be replaced... Many fail in a year or less
