Answer to: Replaced Parts, Now Won't Power Up Except For FansThe most likely issue is the NVIDIA GPU solders have budged. The overheating is the most likely cause for this and it is a REALLY common issue with this model. When you took it apart, even just tilting the board upright would have caused this to occur (Gravity... TY Newton!) There are a heap of guides on refluxing the solder online. http://www.youtube.com/watch?v=Ztzv2OlQJ... THIS IS A TEMPORARY FIX. Once the GPU is under stress again it will break the solder and will need refluxing. Each reflux will reduce the strength of the solder until... It dies.

I'd say you likely have a bad DC board (Ebay sucks :( ... ). Try connecting the keyboard and then the power (No battery). Do you get a light? Will it turn on?

Answer to: Cant add printer - Print Spooler not running error*Print Spooler will not just stop for any reason. The print spooler is set up to restart 5 times after a failure. If the spooler continues to fail, there is an underlying issue causing it to fail. Go to: c:\windows\system32\spool\printers Delete all files inside this folder. Try and restart the spooler and monitor the event log to see if it is still failing. If it is still failing, the issue is a corrupt printer driver. Go to: c:\windows\system32\spool\drivers If your OS is 32 Bit go to : W32X86 If your OS is 64 bit go to : x64 *WARNING - THIS WILL DELETE ALL INSTALLED PRINTERS* Delete all files in this folder and reinstall your printer.
