My laptop is a Fujitsu Siemens V5535 (Viking Direct Xmas day 2008 deal if anyone remembers it!) and is about 18 months old. It still works when plugged into the mains but the battery no longer charges up anymore.
Originally the battery would last for about 1 hour to 1 1/2 hours but has gradually got worse. For the majority of the time I've owned the laptop it would typically last for about half an hour but recently whenever the charger lead is removed I get a critical battery warning (4% battery life remaining) and it will usually turn off within 60 seconds or less.
I use my laptop for a couple of hours every night surfing the net. I don't download much, I normally just go to forums like this, but I do have a habit of keeping multiple tabs open within the browser which I suppose puts a bit of strain on the machine.
Is there any trouble shooting advice anyone can give me or is the battery just knackered?
