Deep Sleep mode for computer hardware

Ever heard of deep sleep mode for computer hardware? Have you faced a situation where a piece of computer hardware just vanished from list of devices in Windows device manager list?Напольное покрытие в гараже

Most common of this issue is to do with the Network controller on Windows 7 but it can affect any hardware that supports a sleep/deep sleep mode to conserve power when not in use. This is all good but the problem starts when such a component fails to wake-up from the deep sleep and Windows then believes that the hardware actually doesn’t exist!

In case of Realtek’s Netword Adapter/Controller driver installation, following message is displayed:

“The RealTek Network Adapter/Controller was not found. If Deep Sleep Mode enabled Please Plug the Cable.

How to fix this?

There are few things that you can try. In no particular order:

How to disable deep sleep mode on Windows 7 (for say the Network Adapter)

Hope this helps!

    I follow your tips up to RAM leave from the slot and additionally leave the bios battery for the mother board. As a result, network card back from deep sleep mode.

    Thanks for your Tips.

    Dear Mr. Arvind
    Resendly My pc shut down automaticaly and it show “system memory crush” and reboot
    again itself. So I manage to clean and re install W7 and I download my motherbord softweare
    from it’s. every thing is working expect Lan. When I install Lan driver, it’s didn’t work and also in device manager. I search in internet and that i found was because of BIOS. I try to enable lan from bios but I didn’t see any word concern with Lan. Here is my motherboard details

    Just to double check, did you physically remove the power plug from the socket? Only shutting down the PC isn’t enough. Good luck!!

    Are you logged in with the Administrative rights when you make the changes (uncheck the box)? If not, that may be the reason that your changes are not getting saved? Other than that I can’t think of what might be the cause.

    Since you have a laptop, have you tried taking the battery out for say about 5 minutes?
