hey guys, please help. I dropped my HP G72 and it wont charge, I just bought and replaced Power Jock, but the same.. even light is not blinking, I think it should be Charger and not power jack, unfortunately I don't have second HP to check, what it may be, I tried with and without battery but problem still exists.

Not sure what you mean by, "replaced Power Jock". Are you referring to the power jack on the computer?

If you dropped the laptop while the charger was plugged in, there is a possibility that you damaged the power jack on the laptop and/or the soldered connections between the jack and the motherboard.

You didn't say how high and how hard of a fall your laptop took, so it's my guess some internal damage is the problem and not the battery/charger.

OK, let me explain, I did replaced Power Jack, I tried another charger, so power jack and charger is OK. there should be some problem on Motherboard, and I want to know, what it may cause on motherboard.

If the fall managed to damage the power jack on the motherboard, it is possible that the stress placed on the jack to damage it, could have also damaged copper traces on the motherboard. Did the motherboard look like it had any damage, like lifted solder pads, in the area of the jack?

No absolutely nothing, motherboard looks like new, there was not damage in the area of power jack, I was 90% sure that power jack was dead, but unfortunately something else, happened and I am trying for 5 hours figure out, definitely, HDD won't be dead, or rams....there is problem with power, If I Press Power Button, that small energy light blinks, Battery is dead, so it can't start..

There must be more internal damage if the charger and power jack (this is the power socket that the power supply lead plugs into, yes ?) are ok. It should power up without the battery. I think the flashing light is a warning that something more is wrong inside the laptop.

Some of the copper tracks are very thin and easily damaged, I would examine the area around the power jack/socket very carefully, on top and underneath.
