|System : Dell 6510 (under warranty) , Windows 7, 8GB RAM etc|
Tried installing latest BIOS, and replacing with a new battery.
Dell engineers recommend replacing motherboard, battery and fan. I found that the replaced motherboards are usually refurbished ones.
1. Are refurbished motherboards reliable. What are the odds that such motherboards do not give similar issues.
2.A refurbished mother board could be an older one that is repaired. So is it advisable to change it.
