Hi,
I have Del inspiron 1521 with Win 7. I lost my original power adapter so bought a universal one from Best Buy for $150. I was working fine. since it was expensive so I bought a replacement one online for like $10. it worked good for only 2 days. now it does not charge at all. but the universal one works but it does not charge i.e. once you take the power out the laptop turns off. i got to know that the universal one uses 90w but the laptop requires 65w. what could be the problem and how to fix it,

Many thanks..

How old is that machine, and are you working off of the original battery?

P.S.-moved you to the Mobile Technology forum, where you might get a better response.

the machine is like 3 years old and its not using the orginal battery. I bought a replacement one about 6 months ago because the it was hardly giving me me any back up power.

Appears to be a dead battery.
Possibly caused by use of incorrect power adapters.
and/or
Lack of calibration.
