I take great care to use my computer correctly....when I'm using the battery, I let it run down zero before recharging it.
the last couple of times ive used the battery, the screen has gone. blank. after a while...the last time at 54 per cent full and this time at 75 per cent.
I can switch it on from the battery again and log. in, but after a couple of seconds I get a blank screen. again.
could some clever person. help me please
