Inspiron 5150 AC adapter and Battery

Question

Although My AC adapter has the right output voltage ,my 5150 is only working with battery. The light of charging battery is off, and I had to charge my the battery on other similar computer to get the laptop works. I tried to update the BOIS, but laptop sees the AC adapter is not plugged in although it is plugged. I hope some one has a solution I can try. Second, Is any one has the power supply diagram on the mother board?

Try a different adaptor, if its not that its probably a bad / loose connection where the jackpoint connects to the motherboard

Hi   My inspiron 5150 also has the exact same problem and im also charging my battery in a different laptop. I have bought a new power supply for it but it was no use. But I have readed on a different forum that it is a power problem on the motherboard so I am also looking for the a circuit diagram for this laptop so I can try fixing it.       Brian

The most likely problem is that constant flexing of the jack point has resulted in one of the legs breaking or coming loose from the mainboard. Check this and resolder or replace if necessary

You're not going to find a schematic of the board - they're just not published.

Measuring the DC output of your adaptor does not give a true reflection of it's ability to power your laptop or charge the battery. As well as giving the correct voltage it also needs to sustain the load (eg: 6.7a for the 5150 & 5160) You need to try a  known good adaptor  before spending loads on new hardware!
