Having problems with your Dell Inspiron 1521 Notebook ?

I'm using a 65W AC adapter to power the laptop, but when I run the thorough boot sequence, the BIOS tells me it can't recognize the power adapter. The battery is trashed too for some reason - the computer won't charge it. Is this leading to the cpu running at 600MHz when it should be running at 1.8GHz?


Answers :

First of all check different battery, different Ac adapter, try to update bios. If none will fix issue then its Motherboard problem
