I bought this Inspiron 1150 laptop in 2004. The battery power can only\nlast about 30 minutes. Recently I used it on battery till it\ncompletely ran out of power. The next day I plugged power cord in and\nused it normally, charging battery to its full capacity. But there's a\nproblem. The yellow light at the front keeps flashing as if my power\nwas running out. How can I tell it my power is already fully charged?\nIf I unplug the power cord now, I can see the blue cylinder power icon\nshowing 100% full.
