I bought a Dell Inspiron N 5050 last week, and recently discovered a problem with my laptop. It doesn't Power On until and unless I Plug-in the charger.

After I plug-in the charger, it boots up fine, and continues to work well after disconnecting the charger.

I don't know what the problem is exactly? I was planning to contact Customer Care, but I wanted to know if I could fix it myself. Please help!

It seems like problem in battery or connection between battery and board. – vembutech Feb 26 '15 at 19:52

pull out the battery and hold down the charge test led till it turns off. if it lights up again a second later how many lights light are how many bad areas in the battery. at least that's how the latitudes work. also check and see if there are any error messages in bios power page about either the ac adapter or the battery if every thing shows good its a good chance the systemboard is bad. if you could test the battery in a known good system that would tell you for sure though. from the description though its a 90% chance its the systemboard. you may be able to update the bios to fix it.

I tried your suggestion. It didn't work. The Charging LED light doesn't glow at all. – hannanessay Sep 4 '12 at 4:02
I also tried updating the BIOS, it said the existing one was the latest. – hannanessay Sep 4 '12 at 4:03
assuming the light is on on the ac adapter before you plug it in to the pc its the systemboard. if you plug the acadapter in to the pc and the light goes out on the ac adapter bad systemboard. it is possible that it could be the battery. We have enough pc's around at work that we just use a known good to test so I never worried about testing a battery much. if its in warranty call dell and have them repair it for you. if you put your service tag in to the site it will tell you remaining warranty. – Kendrick Sep 5 '12 at 0:42

I had contacted the customer care and an agent came over. He replaced the system board but still the problem remained. Later he mentioned that it might be a power button issue. But anyway he suggested me to claim for a new system. I have done so.

Err, the problem is probably your battery. Did he check the battery? – cutrightjm Oct 7 '12 at 3:21
Yes the battery was perfectly fine. It passed all the tests. – hannanessay Oct 7 '12 at 3:28
You pressed the charge button but it didn't light up at all? Each light is supposed to represent ~20% of the battery charge. If none lit up, it isn't holding a charge. – cutrightjm Oct 7 '12 at 3:58
