Laptop motherboard repairs are the most difficult type of laptop repair to to perform and largely utilise the expert skills of electronic engineers not computer engineers. The three main reasons why a laptop motherboard fails:
- Overheating of the laptop motherboard and GPU
- Shock treatment caused by the laptop being dropped or hit
- A liquid spill over the keyboard such as water, beer or wine.
The success rate of repairing these faults in their subcategories is ranked here in terms of success. Over heating of the GPU is fairly straight forward and the success rate is typically over 85%. Liquid spills offer the worst success rate, however the window of improving this largely depends on how soon you can ship your laptop to a specialist laptop motherboard repairer such as Cambridge Laptop Repair
The entire process you can follow consists of some simple steps. If your laptop has suffered a laptop motherboard failure we strongly suggest you review the video which covers the basic faults and crucially the next steps you should take. The video is here.
As you can guess from the information shared by Mark in the video, corrosion caused by liquid drying over the components of a laptop circuit board is the real reason why the failure rate is so high. See the library of images which show the extent of the problem when corrosion sets in.
Laptop motherboard repairs are a complex repair and should only be attempted by a company who have the specialist skilled engineers qualified for this work. Typically the repair process takes 2 hours to complete, however time should also be allowed for stress testing afterwards. Normally when a laptop has had a GPU repair the engineer will use software to ensure the laptop has successfully repaired.
Watching a GPU repair (also known as a BGA repair) is fascinating. A very good video can be found below:[youtube url=”http://www.youtube.com/watch?v=myhVO7NVpXU” width=”690″ height=”388″ autohide=”1″ rel=”0″ showsearch=”0″ showinfo=”0″ title=”0″]
