Tayo,
Do not know the exact architecture of this laptop circuit every manufactures having their own design.in some older desktop generation i seen GMCH is getting supply from the RAM power supply section.so may be some missing signal supply to graphics section can cause the fault symptom.

Very interesting.... is this indicative of power quality or lower tier RAM? I have never heard of anything like this.

Of course Waleed,
Changing the thermal paste on the GPU and CPU in old laptops will increase performance and make chips last longer.

since the think pad was dusty inside that means the fan is also dusty and I am sure the GBU, CBU needed fresh thermal paste. it is a advisble to check these before giving the device back to the customer. thanks for sharing and have a blessed day

Many years ago I worked in a computer repair centre that was warranty-authorized for most major brands. We repaired everything! Compaq computers in those days would beep twice with a BIOS error on power on when there was a RAM problem. It got so that whenever a computer on the bench beeped twice all of the techs around would chant "Two beeps on a Compaq. Reseat the RAM". It just became standard practice for us to remove and check the pins on the RAM modules before attempting any repairs. I have purchased several "defective" computers from thrift stores and pawn shops that only needed the RAM pulled out and reseated.
Good work figuring this one out. I think this knowledge is going to save you a lot of time in the future.

Albert,
I think the best approach is to place the circuit board upside down in the casing so that the dust collects towards the base and not on the circuit board.
Most PC cabinets and laptops are designed in such a way that it absorbs moisture as well as dust from the surrounding environment and causes a short in the circuit.

I also once worked on a dead laptop that even had 2 completely shorted DRam modules in their sockets!
And never found out how the owner was able to get his modules so bad.
