Acer Travelmate 2200 laptop
Try taking the laptop battery out. You can remove the laptop battery by turning it over, you'll usually see some sliders at the bottom, slide them to the unlock position and you should be able to wedge your battery out. The battery usually comes in a very tall and thin rectangular shape.
Once the battery is out, plug the laptop in through the mains power - this may solve your problem, if it does, you'll need a new battery if you wish to use it on the move.
If it does not solve your problem, it is either a faulty power adaptor, or a faulty power supply on the motherboard of your laptop. A faulty power adaptor or battery is the best case scenario, as it's the cheapest to buy a replacement (although it's still expensive - $120 worth in the UK roughly). A faulty power supply on the mainboard generally means you'll need a replacement mainboard which is totally uneconomical, especially with the labour cost to fit it professionally.
If the battery and power adaptor is not faulty, you might as well scrap it and get a new laptop. Good luck Tina! Read More At : TravelMate 302XCi Tablet PC...
