While we could discuss chips, failure modes and board replacements and why they don't fix boards none of this will make your laptop work proper.
Here's an idea. Look on FREECYCLE for a free PC to use while yours is away.
I bought my Inspiron 1520 a little less than a year ago, and it's been giving my problems the past month or so.
Essentially what's happening is the battery is not working with the computer. It is fully charged, but once the adaptor is unplugged, the computer turns off. I have contacted Dell and even with a new adaptor and a new battery, the issue remains the same.
I am pretty sure there is a problem with the actual computer itself(the motherboard? I'm no expert), and the only way to solve it is to send it to Dell for fixing.
While it is still under warrantee, I cannot send it away because I rely on it for my work every single day. If I do send it to the depot, I will be without my laptop for over a week(5-7 business days).
Does anyone have any information or ideas about why this might be happening? Or any ideas on what I should do to fix it myself?
Thank you very much.
