Does anyone know any common causes for my laptop not to power on.
It will not power on under battery or mains. It's a sony vaio v505.
The mains power lead has a light at the tip, so i know that is receiving power. There is also a light on the computer that would indicate the battery charging (which is most the time), this no longer comes on.
When I attempt to switch it on, there is no response, no lights, no image on the screen.
I urgently need my laptop to work again, it is the computer i use at university and although I have backups, the uni computers don't have my software so I would have to work from home, which is not an option. Any advice would be appreciated.
