Hi, I have a dell latitude d505 laptop.. battery does not hold charge when plugged in with an third party charger.. But holds charge for about 2-3 hours when plugged with a brand new DELL charger.. Would any one of you explain this difference ?

Have you looked at the current output of the two different chatges. If the third party one is less than the Dell it would mean that it would need longer to charge the battery. You should be looking at the current in Amps as well as the voltage. Stuart

Is this dell latitude d505 laptop the refurbished computer you bought with a 7-day return policy? If it is you should have heeded the advices previously given you and sent it back. i_Xp/VistaUser

yes.. its me the one who has 7 days of return policy .. i love the laptop as its worth for money.. instead of buying a new one and get hurted when its old .. I love this old one.. i am ready to repair its failure parts .. for me i am learning something with my laptop day by day...

"instead of buying a new one and get hurted when its old"...you bought an old one & get "hurted" by having to pay for "failure parts". For about $500, you could have bought a refurbished Dell with a dual core CPU & 2GB RAM, & it comes with a REAL warranty. "And that's the fishing line, because Sharkboy said so!"
