Ebay purchase junked my Laptop...? PLEASE HELP? 10 POINTS!?

[Sara]

I bought an HP mini 1000 used off ebay last year after christmas and It worked great untill the charger got alittle... Junky...

So I ordered a replacement charger! The title clearly states "AC Power Adapter for HP Mini 1000 1010NR 1010 Battery Charger Supply Cord" So of coarse it's for the HP MINI 1000!

I got the charger in the mail and plugged it all in, but my laptop started quietly, but loud enough for me to hear about 5 feet away, HISSING. Like it was burning a CD kind of sound... But Then I left it because I figured well, If they made a mistake They can pay for it... and I just let it charge. About 40 min later I came back to turn it on. ( It should have been FULLY charged!) It went to the HP screen and SHUT OFF. This happened about 2 more times.

The charger did look differant than the picture... Instead of making an "L" shape, It was an "I". A straight line out. It also fit loosely in my port. Maybe they sent the wrong one?

I got up in the morning had left it sit all night hoping it would work, but NOW there IS NO RESPONSE WHATSOEVER. I have EVERYTHING! MY LIFE! On that laptop, and I can't even save that because I can't get my computer on!

This is the charger I bought: http://www.ebay.com/itm/AC-Power-Adapter...093wt_1230

So my questions are:

What's wrong with my laptop?
What can I do about it?
Can I make them pay for the damage caused by either false picture advertising or not for this model advertising?

I read their feedback... Read the negatives for yourself. Just click the Ebay link for the charger.

Thanks so much for the help!
