I replaced the same part in my HP dv2113 laptop. I found the service manual on hp’s web site. It appears from my research that this is a common failure. I can tell you that even with the detailed instructions it is a big job. The entire laptop is disassembled before you can reach the small board with the connector on it. Poke around HP and you will find the book I am sure. Good Luck

My laptop will not turn on


A) Power On switch is no good.
Power On switch is usually on a Power Button Board.

B) AC adapter (Charger) could be bad. Hasn't charged Battery either, so there is NO power going to the laptop.

AC adapter needs to be checked for output voltage.
It's DC output voltage, and voltage depends on laptop. Usually 15 Volts to 19.
If the laptop manufacturer name, and model number was stated, I could tell you.

C) DC Power Jack problems.
The DC Power Jack is the jack on the laptop (DC_IN), that the AC adapter plugs into.

DC Power Jack either is soldered directly to the motherboard, or has wires attached that end in a small male plug. Unplugs from motherboard to remove, plugs back in to install.

D) Bad Power MOSFET's on the motherboard.
Example using HP Pavilion dv6000 series, and Pavilion dv9000 series Notebook PC's,

My acer aspire 4740g does not power on. i have removed the battery and directly connected to the power supply but still does not turn on.


Problem description:
The laptop is completely dead. When you plug the AC adapter and press on the power button, nothing happens. The laptop has no signs of life at all. None of the LED lights is working.
Possible cause:
1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.
Possible troubleshooting steps and repair solution:
1. Test the AC adapter with a multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2. It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one.
Using a multimeter, test if the power goes to the motherboard through the jack.
3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

You are right, most of the situations like this end up that the charging connector fixed / soldered to the motherboard get damaged because of shaking the connector when ever we connect and disconnect it .

I bought new universal adapter for asus laptop and it charges batery just when laptop is turned off


Problem description: The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause: 1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution: 1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.
2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.
3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.
4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

Its not comeing up on my sram


Hello.

From your comment, I'm figuring you are referring to power.

The most common reasons are the battery, power adapter/cord and power jack.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement.

If no change, the power adapter is probably faulty and needs replacement.

Also, power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

Remove the heatsink and apply new thermal paste or the motherboard may need replacing.

Leave power jack repair and heatseat application to an expert if you are not familiar.

Hope this helps.

If I need to repair or replace my gateway mx6448 motherboard, which is most cost-efficient: to repair or replace? How would I know the difference? I am not an expert, but can I do this repair or...


Depends on what is wrong. Is it the DC Power Jack? The jack you plug the AC adapter (Charger) into?
Average cost is around $100 for a DC Power Jack replacement. (It's labor intensive, but the jack itself usually runs around $8 to $14 )

Most computer 'repair' shops do not have the skills required to perform this procedure.
The easy way is to just replace the motherboard. (Also more Ka-ching in the pocket)

Just a typical DC Power Jack replacement,

Disassembling a Gateway MX 6000 series laptop,

http://www.insidemylaptop.com/disassemble-gateway-mx-model-ma2a-series-laptop/


Some designs of the motherboard, have the DC Power Jack mounted in an area on the motherboard, that DC Power Jack failure is a reoccurring failure.
The motherboard cracks in the area the DC Power Jack is mounted. (Breaking the circuit traces)
In this instance it's better to replace the motherboard. Of course it's going to fail later on.

Your question: "Can you replace the motherboard?"
I have confidence in you, I believe you can.
Doesn't take a rocket scientist, but does require patience.

1) Remove ALL Power to the laptop. AC adapter (Charger), and Battery.

2) It would behoove you to buy, and wear an ESD wrist strap. (Electro Static Discharge)
Connect the alligator clip to a good ground source.
I connect to the metal frame of an empty desktop computer case.
(Average cost is around $3 to $8. Look online for reference. Visit computer repair shops, and stores like Radio Shack for purchase)

Your body carries Static electricity. Static will fry out (Short Circuit) the hardware components inside a computer. Especially a Processor.
With wearing an ESD wrist strap, and connecting to a good ground source, your laptop is safe.

3) There may be as many as 60+ screws. There may be 12, or more different types of screws. DO NOT mix them up! Use a multi-compartment container, and label the compartments for the area the screws came out of.
You can use a clean egg container, (Or two) in a pinch. label each egg holder.

4) You may want to take photos, and make notes as you disassemble. Makes a real handy guide for reassembling. Also nice to have if you get interrupted in the middle.

Obtaining a motherboard:
You might check Ebay. Sounds like advertising, but it isn't. Just one of my sources.
Also check Laptops for Parts on Ebay.
Some sell a laptop that has a broken LCD screen as the only fault.

The pin on my power connector is broken


If you are referring to the pin on the AC brick (the part that actually plugs into the wall), then you don't fix it. Due to risk of fire, it would need to be replaced.

If the pin is on the laptop itself, then you would either need to replace the motherboard or obtain a DC jack and sodder it to the motherboard after removing the old one. (Generally, the DC jacks are not field replacable.)
