Suspend / Hibernate Problems

[CarlosinFL]

I've removed Windows 7 from my Dell Latitude E6500 laptop & installed Ubuntu 10.10 which worked great out of the box but when I shut the laptop lid, the machine goes to sleep but when I try to use it again, I can't wake the laptop up from sleep. I can see the illuminated keyboard light up but I have to manually hold the power button down to shut it down and start it back up again from scratch.

Can someone please tell me how to get this working like it did in Windows 7 or at least get the machine up & running.

Anyone? I've tried searching and couldn't find any help or tips. It's extremely annoying to have to force my laptop to shutdown when I'm done using it because I know it will lock up if I shut the lid or let it just fall asleep from idling too long.

Please help...
