How to remove the bottom of a laptop to tighten the power supply outlet


You will probably have to strip it right down to get the motherboard out.
The socket might need resoldering. if you are not technically minded you would be better off taking it to a repair shop. You can do more damage than good if you are not careful. Youtube have a lot of videos about disassembling laptops / pc's if you want to do it yourself.

Battery is showing 100 percent but you unplug power supply computer shut down also when you wiggle cord power shuts down


The DC jack in the computer has detached itself from the motherboard causing intermittent shutdowns, the laptop must be dis-assembled to re-solder the jack back in place, and may need to replace the DC jack if the old one is not suitable.

The ac power plug was broken loose on my sony vaio vgn fw140e and finally the laptop failed to power up. I'm pretty sure the power adapter came loose from the mother board . I just don't know how to fix...


1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

Unfortunately there are many sellers of DC jacks for your model and several others. Some of these people sell sub-standard DC jack replacements which are not designed for your laptop, but will fit in the same hole. If the mount points for your DC jack didn't fit the same pattern as your original one then it simply is not the right jack for your laptop. You can suffer issues such as improper grounding, voltage applied to ground and vice versa with some severe consequences. This can damage not only your charging circuit, but may well cause your battery to overheat and rupture. Remember, that not all DC jacks are designed the same way, In fact most manufacturers design their jacks as different from the competition as possible, whether this is their intent or not is irrelevant. Your Dc Jack, however suffers from the dreaded floating pin problem. The main bullet type pin you see at the middle of your jack tends to separate and spin freely, and can be repaired by simply soldering the pin mount on the back. Try repairing the pin on your original jack and reinstalling until a new jack can be found and I'd be willing to bet your problem goes away.

REPLACING A BROKEN POWER JACK ON A SONY VAIO


Hi:
The power jacks can be bought on line for less than $10, but the fun part is the repair. The laptop must be dis assembled to get at the power jack, and when you do get to it, it takes a deft hand and soldering skills to swap one out successfully.
I have done a few and am personally only about 50% successful. There are electronics shops that swap out the power jacks for about $150, and guarrantee their work.

Tech manual for Asus Z96J lap top. need to replace the dc power jack how do I access the power jack?


For all the function and portability laptops provide, there are also some drawbacks. The biggest problem with laptops is with battery life. To get constant battery power, the laptop has to be plugged into a wall outlet. The wall plug then connects to the DC jack in the back of the laptop. The DC jack is no more than a little piece of metal that conducts the electricity for the computer. These DC jacks are known to be fragile and break off easily. If this happens, you can open the laptop and replace the DC jack yourself.
  1. Step 1 Remove the internal battery pack from your laptop. Flip the laptop over and locate the release button for the battery pack. Hold the button in to slide the battery pack free. It is important that you remove the internal battery pack as well as unplug the power cord from the wall outlet to prevent risk of shock while working inside the laptop.
  2. Step 2 Unscrew all of the screws on the underside of your laptop. The number of screws will depend on the model of computer. There should be one at each corner and then one or two screws that hold the hard drivemag-glass_10x10.gif cover in place. Once the screws are removed, take out your computer's hard drive. Newer-model computers will have a hard drive that slides out of the side of the computer.
  3. Step 3 Locate the two screws at the back of the computer that hold the laptop screen's hinges in place. Once these two screws are removed, gently pull up on the screen until you clear the silver pegs from the holes in the laptop's body. Two wires lead from the screen into the computer, so ensure you do not pull so hard that you disconnect them. Carefully set the laptop screen aside so it does not get damaged while you work inside the computer.
  4. Step 4 Separate the two halves of the laptop's body to expose the computer's internal components. Flip the keyboard on its face, making sure not to disconnect the keyboard's connector. Underneath the keyboard will be a metal plate that covers the computer's motherboard. Unscrew the screws that hold this plate in place and set it aside.
  5. Step 5 Locate the DC jack for the laptop. Most all laptop's DC jack outlets are located at the back left corner of the computer. Using your tweezers, remove the old DC jack. Identify the slot in the motherboard that the old DC jack came out of. If the DC jack was loose before you removed it, there will be a small slot at the base of the opening in the back of the computer that the DC jack pops into. Using the tweezers again, slide the new DC jack into this slot until you hear a clicking sound. To hold it in place you can solder the new jack to the motherboard, or simply superglue it in place. Don't use too much superglue or you will risk losing the ability for the jack to conduct electricity.

How to open the power jack for GQ-zx 5361 laptop . and replace it with new one...


1.ESD wrist ********, connected to a good ground, work on a table.

2.Remove the AC adapter if plugged in, and the battery.

3.Completely disassemble the laptop, down to just the bare motherboard in your hand.

4.Use your soldering station, and I advise using a soldering wick instead of a desoldering tool, on the DC Power Jack leads. Works much better.
Remove the old DC Power Jack, being careful to not burn the motherboard, lifting the circuit traces, and rendering the motherboard useless.

5.Clean the DC Power Jack mounting area with Isopropyl Alcohol, and Q-tips to remove the residue. [WARNING! Isopropyl Alcohol is =>Extremely Flammable. I use the 91% Alcohol version]
Make sure the circuit trace mounting hole has a good tinned surface.

6.Install the new DC Power Jack in the circuit trace mounting holes. CAREFULLY apply solder to the DC Power Jack leads, and be sure to make good solder joints.

7.Reassemble the laptop

Sorry, I don't have access at present to Fry's GQ line of laptops for a Maintenance and Service Manual, to give you a link.

Thermal cooling assembly replacement or Thermal paste


Frankly there is seldom a reason to replace either. The thermal grease is not damaged by removing the assembly and, as long as there is still plenty, you can just reassemble it. There is absolutely no reason to replace the assembly.
