The most likely cause, if Nvidea GPU is an overheated GPU causing the system to hang. Replace the GPU.

SOURCE: dead short on power jack

Should be battery first, Then AC adapter (Charger)

Dead short on DC Power Jack?
Are you aware of how a DC Power Jack is made, (Component structure), and how it attaches to the motherboard?

If not, allow me to explain. This is an example of an average DC Power Jack,
http://us.st12.yimg.com/us.st.yimg.com/I/yhst-42877593004970_2046_1336946

The outside housing of the DC Power Jack, is barely larger than the outside of the AC adapter (Charger) plug.
It's about a 1/4 inch wide, 3/8 inch inch tall, and 1/2 inch long.
The body is made of plastic.

The outside shell opening in the body is the Negative contact.
The pin in the center is the Positive contact.

Those flat metal prongs, or pins, you see in the photo, go down through the motherboard, are are soldered on the bottom side.
The photo of the jack is upside down, in relation to how the jack sits on the motherboard.

When the 'Charger' plug is plugged into the power jack, it can get bumped. A hard enough bump, or repetitious bumps can damage
the center pin mounting, break the outside metal shell loose, and/or break the plastic housing.

It can also break the solder joint/s for those flat metal pins.

AC adapter unplugged from the laptop, battery removed, see if you can take a pencil eraser, and move that middle pin around. You may see the entire jack move.

There is also a large number of laptops, made with a defective motherboard design. To explain, I'll have to give you a crude example.

Think of the laptop motherboard as being a 1 foot square. (It isn't. It's irregular shaped)
Now along the edge of the 1 foot square, attach a 2 inch square.
It's actually all one piece.

Due to accidental bumping of the 'Charger' plug while in the power jack, this 2 inch 'Peninsula' can break away from the main body of the motherboard. (1 foot square)

There are circuit traces on the motherboard. (Think of a circuit trace, as a Very, Flat, Thin, copper wire)
These circuit trace can become stretched by the cracking, or breaking away of the 2 inch 'Peninsula'. They can then be exposed to circuit traces they're not designed to touch. This can cause a direct short.

(Also, due to the bad design of these motherboards, the laptop user can be just using the 'Charger', in an everyday situation, and this 2 inch 'Peninsula' can break.
Just by plugging in, and unplugging)

SOURCE: how to replace power jack on a105-4094 laptop

It is not easy. If it uses the standard round connector you need to find a replacement one (Radio Shack had the one I replaced) Then de solder the old one then solder the new one. This takes special tools you can also get at Radio Shack but if the connector is too close to small components then you will need a soldering iron with a variable heat option. Sorry long way to say.
Yes you can, on a skill-set from 1 to 10 this is about an 8
You will spend $70 (Retail) in tools for a fix the manufacturer will charge you $80 + Shipping for. Plus the manufacturer is less likely to leave you with a cold solder joint and melted plastic.
Sorry about the bad news.
Hope this was useful

Won't turn power on


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:http://www.ifitjams.com/lappower.htm

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

My battery light is off.


The battery might be dead. Batteries only have a useful life and after that they have to be replaced.

Does your laptop work ok off the AC Adapter Power Cord? If so, your battery is dead and your power cord is good. If the laptop does not work off the Power Cord then either your Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. In either case a good battery will not charge if the power cord or the DC Jack is bad.

Check your DC Power Jack which is where the power cord plugs into the compute. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Dead could be a shorted MOSFET in the CPU line which is common for the age. Need to verify Voltage at Jack and the I/O's the BIOS chip..
