Gateway NV53 laptop
Hi, I was rapairing a laptop (originally had overheating problems, also randomly turned off, presumably due to the overheating problems) and after the circuit board disasembly I noticed a microchip that was damaged. I have no idea how it happened- it could posably be due to someone else taking the computer apart and bumping the chip (there was 8 screws missing from the back before I began the disasembly).
As far as the damage, it’s a microchip (resistor?) and it says “zz-20k” on the chip. It has 5 legs, of the 5 legs, it has 3 on one side, 2 on another side. One of the PCB pads was completley ripped off and another one was ripped off half way (50% of the pad is still attached so it should be working still I would think). The chip was installed but the legs were bent, I could see the pad lifted and I tried to straighten the legs out and the entire chip snapped off, pulling the pad up with it. Once it was removed I tried to straighten the legs out on the microchip but one snapped off the main microchip as I bent it to straighten it out.
Below are some diagrams explaining the damage:
Below each "-" represents the leg on a normal chip
Below represents what I have left (x represents no connection)
If I replace the microchip, below is what I would have for a connection
The last leg has the pad pulled off so that can not be attached back.
Does anyone have any idea as to what this controlls? I will post actual photos below. The micro chip is “secluded” off to the side so I am hoping it may not be important (for ex if its for the 56 k modem or something- not needed).
I don’t know if I should try to reattach it as is, or if I should try to find another microchip to connect the 4th leg to the board? Or is it not worth it since one of the pads is ripped off (that would be assuming it’s a crutial component)?
