My hp laptop keeps disconnecting while my AC adapter is plugged in.

[Kamel2233]

I noticed this problem in my laptop while charging it today.

My laptop was in sleep mode and my AC adapter was plugged in and it was charging and I noticed that the charging light kept changing orange and white it stays orange for about 10-20 seconds and then turns white for another 10-20 seconds. When I turned on the laptop whilst charging it, I noticed that the charge keeps connecting and disconnecting so it tells me charging for like 10-20 seconds and then it disconnects for another 10-20 seconds. The laptop is on while the battery is present and with my AC adapter unplugged so the computer still works with the battery in my laptop powering it (with no AC adapter plugged in).

How do I solve this issue? thanks in advance
