Upgraded my laptop with 8gb ram now have sleep problems

I have a toshiba satellite a660 upgraded the ram now when the computer gets woken from sleep it restarts it self is there a way to fix this

I'm running windows 7 64 bit

Just a guess - recreate the Hibernation File and make sure it is as large as your current total RAM size.

I can't find a hibernation file where do I look for it

The hibernation file is named 'hiberfil.sys'.

Source: What is hiberfil.sys?

This tells how to do it:

Hibernate - Change Size of hiberfil.sys File

The hibernation advice is good, if the laptop is using hibernation.

Did the laptop wake from sleep in a few seconds, before, or did it take minutes?

Hibernation copies the contents of RAM to a file on the hard drive, and restores RAM from that when the laptop is awakened. It works even if the laptop is powered down.

Normal S3 sleep puts the laptop in a low-power state. The contents of the RAM are maintained, and the PC restarts in seconds. If power is lost, the laptop's state is not restored.

If you're having a problem with S3 sleep, I'm not sure what to suggest.

Or the RAM might create problem for the motherboard of the laptop because it the motherboard might not support 8GB RAM.

Crucial.com confirms that the model supports 8 gigs of RAM (that's the fastest way to see it without spending hours googling)

Some quick googling dragged up another requirement though, from here.

"It is a requirement for your Satellite A660 to be running a minimum of BIOS version 1.90 prior to upgrading to the 8GB maximum."

So you may have to upgrade the bios to enjoy 8 gigs of RAM.
