Reflow by Baking T61 due to G86 Issue

Sister’s Lenovo Thinkpad T61 with the NVS 140m GPU would not turn on anymore. The LED’s would flash, the fan would spin for awhile and then stop. No activity. I assumed it was the bad NVIDIA GPU issue that requires a solder reflow or reballing to fix it. So I disassembled my sister’s computer and did an oven bake reflow.

1) Disassemble laptop. Remove as many components as possible. Leave the plastic black tape is is on certain components such as part of the GPU.

2) Preheat oven to 385F. Mine was analog.

3) Cover the whole motherboard with aluminum foil. Make a square whole to expose the GPU. Make aluminum balls to prop the motherboard up. Put some aluminum foil on a baking tray to prevent contamination.

4) Bake with GPU side up for 5-10 minutes. I did 8 minutes.

5) After baking, open the oven for a crack and let it cool for about 20-30 minutes.

6) Take it out a reassemble/test. For your test, you would need your CPU, HSF, memory, LCD.

If it doesn’t work, try baking it again, or get a new computer!
