Note** please vote if u appreciate this project,thank you

Have dumb this gateway NE522 laptop in my drawer for about two years probably because have got another to use, so when I saw this contest I know its worth fixing it and sharing all the repair processes am going to make it so easy so u can fix yours also. Also am going to be living a link on each step to watch as videos.

Supplies

PARTS REPLACEMENT
* MOSFET/transistor and diode
I got mine from local store.

TOOLS USED
* hot air gun and soldering paste
*tweezer, screw driver,
You can get them in local store.

Removing the Touchpad Assembly

* I remove all the screws at the bottom of the laptop,at the under cover and also from the battery compartment as shown in the image
* I separate the bottom panel from the touchpad assembly by inserting a plastic opening tool BTW them.
***note you can check your user manual on how to dismantle your own type of laptop however this process works for most.

Separating the Connecting Wires and Belt

* I took an extra care in removing all the belts and adjoining wires from the port using tweezer in order to completely separate touchpad assembly from below assembly.

Removing the Mother Board

* I remove all the five screws and connected wires on the motherboard which include the (LCD screen flex,and the hard drive ) and lift it up.

Inspection and Diagnosing

* I did a physical inspection and notice a blown off transistor/ MOSFET this signal why the laptop is dead. You can test a failed one by yourself pls watch on the link https://youtu.be/PesCvN9losE

Replacing the Mosfet

* using hot air gun and soldering paste
* clean the area with soft brush to remove dirt
*apply soldering paste on the area u are working
* grap the hot air gun there is two knob attached to it airflow and temperature adjust to your need
*when uve got your settings, carefully aimed the nozzle at d area back and forth until the solder begins to flow,carefully remove/ reposition the MOSFET by grabbing or nudging it with tweezer
* be sure to clean the board with methylated spirit to clean the board, watch on YouTube https://youtu.be/oaJvjZsxfP8
**note be careful with hot air gun and work on heat resistant materials.

Testing

* I couple every thing and connected my charger thank Jehovah it brings out the charging light but its not powering on at least weve resurrect it ,* so I remove the motherboard again.

Testing the Diodes for Shorts/failed

I started testing the diodes so I noticed a failed one, Pls click the link to watch how diode can be tested with your multimeterhttps://youtu.be/tLPeG2YVM3Y. I just removed it since its a parallel connection which means there are more than one deploy to do the same work but you can replace it using the method on step 5.

Coupling and Testing.

I couple everything and tested it ,it work and that is how I brought the dead laptop of over two years back to life thank u for stopping to see my instructable.
