There may be something wrong with the battery or with the power Adaptor...

take your laptop to a repair centre.

Hi....I think your power adaptor needs to be replaced....these can fail in as little as 6 months and do not cost much to replace.....make sure you buy the right unit.

The only thing I can think of is that your mainboard is screwed.

and if i don't get 4 points for answering this i will be angry...
