In reply to Alfredo. @ Alfredo,

I could replace easily the fan cooler of my HP notebook G42, but still it doesnÂ´t turn on, what else can I do?

Did you buy a new fan or used one? It's possible your replacement fan is bad. Maybe you just forgot to plug the fan cable into the motherboard? You can purchase another fan and try replacing it again. Fans are not expensive. If you still have the same problem with another fan, most likely this is motherboard related issue.

In reply to Cesar. @ Cesar, What is your laptop model number? I can try to find the Bluetooth card location in the service manual.

My cq42 do not accept the RAM in spare slot, only one slot accepts either 1 or 2 GB. Is there any connector on MB or have to change values in Bios? There is no connector on the motherboard. Also, there are no special settings in the BIOS. The new memory module should be detected and configured automatically. If your laptop doesnâ€t see any module in that slot, most likely itâ€s bad slot. I assume your new memory is compatible and not faulty.
