have just bought a second hand laptop, when i switch it on then after about 5-10 mins it gives 1 beep every 5 seconds for about a minute then shuts down and the stanby light flashes(pic of moon). have left it for a hour and then switched it back on and the battery seems to be flat with only 3% charge(power settings) and starts beeping as soon as i switch it on but as soon as i plug the power lead in it stops bleeping. has it anything to do with setting or is it a dodgy battery.
charged it up for about 4 hours turned it on and the battery indicator said 99% then after about 5 mins it started bleeping and turned itself of so i switched it back on and the battery indicator said 3% so i t must be the battery, as it works ok on the mains.
