Question about Dell Latitude C840 Notebook

1 Answer

Dell C840 won't stand-by when closed.

Since installing XP, I can't get the laptop to go to stand-by when I close the lid.

Windows does not give me that option when I access the advanced settings in Power Option Properties.

Is this a hardware issue?

    There is no drop down window for "stand-by" or "hibernate" in Power Options.

    My HP ze4500, also running XP, does give me these options.

By default, Windows 7 is configured to go in sleep mode whenever you close the lid on your laptop. While this is generally preferred by most users to preserve the laptop's battery life, it might be useful to disable this process. Many laptops provide the ability to connect an external display. In this case, closing the lid would also prevent any signal going to the external display. If you would like to stop Windows from shutting off your monitor when you close the lid, access the Windows Power Options component and disable this feature.

Windows XP:

By default, all laptops either go on standby or turn off to save precious battery, but you can override these rules from the Power Options (XP) in your control panel (Start > Control Panel > Performance and Maintenance > Power Options) and click on Advanced Tab and override the settings according to your preference.
