Did standby or hibernate used to work on this PC, and this is a new issue? Or have these modes never worked?<br />
<br />
If it used to work and just recently stopped, have you made any hardware or software changes recently?<br />
<br />
The problem is an ACPI conflict. You need to check your hardware and your drivers. Make sure your drivers are all up to date.<br />

Hello,<br />
When I try to enter standby or hibernate, my dell latitude will freeze up on either the preparing to hibernate screen (for hibernate) or with a black screen (for standby), while keeping on the system and fan, and the power light stays on, and the wifi light stays on. the only to get the system to respond is to hold the power button to do a hard shutdown and turn it back on. I tried system restore and it fixed the problem for one standby cycle, but now again i cannot go into standby anymore or hibernate. any help is greatly appreciated. THanks!

Computer Freezes when entering standby and hibernate

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
