Inspiron 5150 laptop battery time?

Question

I have a dell inspiron 5150 and the time it takes to get from 100% fully charged to 0 is ridiculous. I heard it was supposed to be at least 3 hours, but mine stays alive for about 15 or 20 minutes without the charger. i know its not the battery itself bc we got it replaced multiple times

any suggestions?

Answer 1

make sure its plugged in correctly, or the charger

Answer 2

Doing a BIOS update might resolve this issue. It can be downloaded from www.support.dell.com. Its advisable that you call tech support so that we can guide you easily.
