LOL, sounds like your tablet has seen it's better days. See why HP got out of the Tablet business? They are nothing but trouble.

It does sound like the DC jack, you will need to dismantle down to the motherboard, chances are the jack pin is not making proper contact with the main board, "the board is double foiled" when board has been completely removed you need to resolder the points where the DC jack sits. This is a very tricky repair and to involved to give step by step instructions, I recommend a professional.

You will need to First Order/Receive a New Replacement DC Jack...
Then The Laptop Needs To Be Disassembled Down To The Motherboard.. let me know if you need full instructions on the steps involved in the DC Jack Repair..

Motherboard or harddrive? I'm betting it's more towards the motherboard. The DC Power Jack to be more specific. This is the port where the AC adapter, (Charger), plug is plugged into.

The DC Power Jack is not much bigger, than the plug for the AC adapter that plugs into it. There are small pin leads that are on the bottom of this jack, and they go through the motherboard, and are soldered to the motherboard.

Accidental bumping of the AC adapter plug, while plugged into the DC Power Jack, can damage the jack. It can break the connections for the adapter plug, and/or can crack the solder joints for those small pin leads.

[Laptops use DC electricity. A flashlight battery, and a laptop battery, are examples of stored DC electricity. DC electricity has two poles. Positive and Negative. The DC Power Jack has two connections. Positive and Negative. {Even if the DC Power Jack has multiple holes in it]

There is also another known problem associated with DC Power Jacks. It may stem from a bad motherboard design.

More to the point, the area where the DC Power Jack mounts on the motherboard. In this design, the DC Power Jack motherboard area, is almost a separate part of the motherboard. It's shaped like a Peninsula. (Think of an island, with one side connected to the mainland)

This peninsula shape, has the tendency to crack away from the main body of the motherboard. Circuit traces are broken.

When the AC adapter plug is setting in a certain position, it presses the two broken halves of the circuit traces together, for a momentary contact. As the AC adapter plug is moved from this position, the circuit trace halves are moved apart, and there is no contact.

(No distribution of electricity from one circuit trace half, to the other circuit trace half. Think of a circuit trace as a very, thin, flat copper wire. When a circuit trace is broken, there is essentially a wire that is broken into two parts)

Solution?
See if the DC Power Jack can be repaired, (Solder joint connections re-soldered), or replaced.
If the DC Power Jack motherboard area is the aforementioned peninsula shape, it may require replacement of the motherboard.

There are very FEW, computer repair shops that have the technical expertise to replace a DC Power Jack. Easy fix is to simply replace the motherboard. (More $$$$$ too)

However, some laptops DO require replacement of the motherboard for this repair.
Bad motherboard design, for the DC Power Jack area on the motherboard.

Re-solder DC Power Jack solder joints? (IF, this is the problem) Average is $50 to $75 (US)
Replace DC Power Jack? Average is $125 to $150. (US)
Replace motherboard? Depends on the Gateway model. Could be $225 to $400 (US)

[Yes, most of the time the cost warrants just replacing the laptop itself, as the cost of replacing, is close to the repair cost)

Just to SHOW you ab average DC Power Jack, and the repair involved of replacing. (Doesn't show you, that the entire laptop needs to be disassembled, down to the bare motherboard in hand)

This is NOT a recommendation to replace the DC Power Jack yourself! It is just for knowledge of what is partially involved. (You can accidentally burn the motherboard when desoldering, or soldering, rendering the motherboard useless)

Most, if not all computer manufacturers do not include these instructions, & for good reason too. You should not attempt to replace a DC Jack if you are not very technologically savvy.

Repairing the actual DC Jack itself requires you to strip the notebook down to the motherboard. From that point you will need to de-solder the old DC jack (very carefully) and then solder a new DC jack to the motherboard. After those steps are complete, you need to test the power using a voltmeter. If the voltage matches up to that of the computers you can continue. After you have finished all of that the only thing left is to put the notebook back together.

More detailed instructions as well as photos can be found by doing a Google search. Try entering the make and model of your specific notebook.. Who knows, you may get lucky and find a link with how-to photos.
