Solved! hp G72 doesn't charge battery and doesn't power up if battery is roved

[adeyemi.as]

I have a HP G72 laptop that doesn't charge battery, the power jack doesn't light up at all but if battery is fully charged externally and plug into the laptop, the system will show AC power is plugged in but still doesn't charge the battery, and if I remove the battery and connect the AC adapter only, the laptop does not power up.... Please help with how I can power the laptop without the battery

Try charging it while the laptop is turned off, not sleep or hibernate, but off. If it will charge when it is off, then I would say your charger is going to need to be replaced (as it isn't putting out enough power to both run the device and charge the battery). If, however, it won't charge no matter if the laptop is off or on, then I would start with replacing the battery.

Thanks but I have tried 2 other batteries and it gives same result, I have equally tried my charger on other laptops and it works perfectly, I tried another charger on my laptop, still gives same result.... Could the DC jack be the issue

It could. It could also be the connections where the laptop and battery meet. Then there is also the charging circuit.

Okay, then this is probably a board issue as there is only a single board in the laptop?

Depends on the laptop. I haven't been in one of yours, however the circuit is most likely on the motherboard itself. It is not common for it to be on a secondary one. Here are two links to maintenance and repair manuals on that device. I am including both as they 'say' they are for the same device, however they are different in size (number of pages, etc.).
