Acer Aspire 4530 BIOS Problem?

I recently helped my friend to format her laptop(refer to the title) and it worked fine for the first couple of days. I installed Ubuntu Natty Narwhal version 11.04 and it worked flawlessly. But suddenly, without warning, the laptop suddenly shutdown while she was browsing the web (Youtube, just to be specific). Now the laptop can only be turned on(the power button lights up, and the HDD lights flicker erratically) but the screen is blank and stays that way even after 10 minutes. Is there a solution for this or do I have to ask her to send it to a service station? Please help. Thanks in advance!
