Fix a Dead Laptop Based From my Experience

A few days ago my laptop turns off itself after I play heavy 3D games, after that I try to turn on back, but no response. my laptop died completely. black screen, the indicator light off and no fan noise. I had a moment of panic, lest my laptop is broken for ever, but then I hope that my laptop can be turned on again, with my assumption: the broken is on power part of laptop motherboard. in evening, i begin to unloading my laptop. in the first, i test the adapter and its was still functioning.

a rather complicated is to remove the screws that bolt is on the laptop, because there are many, varied and sometimes a little place tucked among the components of the motherboard, so no visible in eye. before unpack the laptop, I set up some equipment, ie: Pliers, a different set of screwdrivers, motorcycle lamp and cable (multitester replacement).

I begin by dismantling the screw at the bottom of the laptop and then open the keyboard cover, remove the keyboard and the cord, remove the processor heatsink and fan, disconnect the touch pad cable, remove the DVD ROM and hard disks, RAM and WIFI off, unplug the display, then remove the screw from the mainboard . There are two screws that are quite unique, I use pliers to open it. this screws is screws of external monitor port on the back part of laptop.

then after mainboard succeed regardless, I clean the dust attached to the component and PCB. I wish I could find a burning component, but it did not exist and all components appear normal. then I look at the bottom of the motherboard to see tin on circuit path components. I look at the motherboard power jack the tin solder is worn out (I suspect the cause is overheating, because the past few days I often use to play the game) after my check was correct, no electrical current flow in this section, (whereas the power jack of the adapter I have entered).

then I use a razor blade scrape before I solder again, then after I solder the power jack corectly, start to test my motherboard by plugging the adapter, and when I press the power button, the indicator light turns back. I was quite relieved because my laptop is not damaged in main chipset. after making sure the motherboard is normal, I began to assemble again. then I tried to turn on the screen, RAM and hard disk installed in the state. turned out to be a way back to normal but the BIOS must be set back, can not directly boot.

in the time to disassemble the laptop, I could also remove the BIOS battery, so the BIOS settings back to default. I recommend the BIOS battery and processor need not to be removed, let it stick with mainboard. for other cases maybe the problem can vary. I am writing this in hopes can be used for reference for you (you are possibly problematic in laptop that is totally dead).
