Today I had some free time at home so I took advantage of the free time to do maintenance on my brother's computer model MAGALHAES MG101A4, as it has been presenting a failure where there are times that turns on but does not give image, in such a case that the problem is not solved change the motherboard for one that I already have a spare that works perfectly.
The materials that I have used to disassemble and make a quick maintenance of the computer were:
- Screwdriver of shovel and of Estella.
- A small paintbrush.
- Coolant paste.
The first step is to remove the battery to see the screws that are in that place, then remove the screws that hold the motherboard to the case in the back.
After removing the screws, we proceed to remove some pins that are in the same place where the battery goes, it is to release the keyboard of the computer, then remove the keyboard by loosening a lock that is so that if the keyboard fex comes out, and remove the protector that is secured with a screw, it has two screws in this proctor but it had already been disassembled previously and damaged where the other screw goes.
After removing the protector I remove all the screws that hold the case and the hard disk, once the screws are removed I lift the lock that holds the hard disk fex to remove it.
I continue removing the network card that is fastened with a screw and remove the cables that is subject to this, under this are two Flex that are the sensor and the mouse keys of the laptop, I also remove the ram memory card that is located near the previous ones.
Having all this area clear process to remove the front casing of the laptop, not having the screws that hold it is out of pressure, I use a paddle screwdriver.
Once I have the boards in sight I proceed to remove the connectors that goes to the motherboard and the audio and current, removing plumber the plate containing the power button, USB ports, audio, to clean the dust.
Already almost finalizing process to the motherboard removing the cables of current of the ventilator, the cable of the screen and all the others that is in this to clear the card and to retire it easily, to remove the dust, and to change the battery of the BIOS.
When removing the motherboard, the cooling system of the CPU is clear, I proceed to remove it to disassemble and clean it, removing the residues of the thermal leg, to put it back in place and put a new thermal paste.
With this ends the cleaning process, I put the parts back in place, in my case I put a motherboard that I had as a spare because when testing it was still with the fault leaving it to check later to see if it has a solution to the fault, remaining in operation.
Greetings my dear colleagues I hope you find my post helpful, I say goodbye and have a great day.
