Question

Lenovo Thinkpad Major Problem

Oct 11, 2015 7:47AM PDT

My five year old Lenovo Thinkpad laptop used to shutdown for over-heating issue. Yesterday i gave for repairing and that man cleaned fan and applied thermal grease between processor and heat sink. After that it didn't improved and temperature used to increase randomly and shut down. Then i tried to do myself following experiments.

First: I applied toothpaste after removing earlier thermal paste and it also didn't worked out. Laptop was opening but shut down randomly with high temperature.

Second: I cleaned toothpaste with wet cloth and dried that place. Then insert a medicine packaging aluminium foil in that place and after that laptop isn't opening.

Finally i removed that packing material and started laptop but it isn't opening anymore. Please suggest what could have happened to laptop and how to solve.

Looking forward your reply. Thank you.

Looks like a burned CPU. Replace it or buy a new laptop.

Then be sure to use it on a cooling pad and regularly use canned air to keep it clean, and most likely your new laptop will last a few years, especially if you buy a three year warranty.

While interesting choices on compound.

It's all the wrong stuff. I'd redo the compound, be sure the heatsinks, fans and vents at clean then check fans. Replace failed or slow fans. Then put it on a cooling pad.

It may have been running hot for too long and it's gone so be ready for that.

Motherboard probelm
Oct 13, 2015 8:57AM PDT

I contacted local service center of lenovo and they say motherboard is no more working and needs to be replaced. They also says there is no guarantee even after replacing motherboard laptop will work because other components (processor, ram) may have failed. The problem is that model of laptop is no more in market and lenovo customer care says they don't have motherboard and i can purchase from outside or repair from outside.

1) Is it wise to get a motherboard from outside and how reliable?
2) Can mother board of laptop be repaired and how reliable that it will work?
3) How long the laptop will work if motherboard replaced as already 5 years old?

Please reply. Thank you.

Is gained by doing. Here if a laptop has failed this badly my advice is to move on. Yes you might find parts on ebay but you accept the risk.

As to questing 3. Just like your car, you keep fixing it to keep using it. No one will tell you it will fail in weeks, months or years. Just that is will need work.

If you're using Toothpaste as Thermal paste, I would say that you shouldn't spend the money on old parts as your skills are lacking.
