My HP G60 laptop is plugged in but states 0% available (plugged in, not charging), and when we unplug it, it goes off - Do you know what the problems is?

it needs service,
if the charge circuits fail, it needs to be repaired.
do know the charge chip is on the MOBO. so , not easy to fix.

my guess is the MOBO is bad,(the charge chip blew out)

Make sure the laptop is charged.

If your computer is plugged in and charging, unplug it and then press the power button, then plug it back in. If that doesn't work, remove the battery, then pop it back in and do as i said above.

Hope that helps.

This is not a laptop jack issue?

You need to replace the battery as it has expired.
They are available by typing the battery model number or laptop model number into ebay or Google or indeed any search engine.
Hope that helps.

Try charging the laptop without the battery. If it does not work, Check the port of the charger if it blinks any light. If it doesn't, then I guess you would have to get a new charger. If it still does not work, then the power pack should be examined by an expert.

Bro I think it was drain becuase of it's quality and it is easy to destroy through unwanted electrical charging of battery. but if you have waranty of your battery who can change it to a new one.

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all.
OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time.
If the battery drops to an unacceptable charge level then the battery needs to be replaced.

Try taking out the battery, (when it is not plugged in), then plugging it in (with no battery in it), and try turning it on.

try to check the panel for the lcd. it might be busted
