G460 does not wakes up from sleep but no display

[krishanum]

Dear All

I have bought a Lenovo G460 about a month a go. I have set it on High Performance power plan through Lenovo energy managment.

When ever the system goes to sleep in balanced power plan, after i try to being it to wake the screen stays blank, though hard disk keeps running and all other lights come up. So i put it on performance mode, which only switches off the display. But even then the same problem remains.

System Config

Processor: iCore 3 2.16 GHz

Video: NVidia 310M

Ram: 4 GB

OS: Win 7 HP 64 bit

Nvidia Driver Version: 188.88

Tried with NVidia latest drivers(256.88) but the problem remains. Tried bios update yesterday and update was very successful but still the problem remains.

Thanks

For all your help

Hi,

I am also facing the same problem. My laptop configuration is also same.

I read on some website that it could be Window 7 problem.

I am not sure if they have any sleep key configured in keyboard. If it is not, we need to do the same by using microsoft help.

Thanks

I dont think it is a Windows 7 issue. I have used a lot of different Win 7 laptops, like the one I get from work, and it does revive fine. I think this issue is related to some driver and may be the video driver may be the culprit. Or atmost may be the wireless driver.

Search at the forums. Family G460/G560 had a lot a troubles.

I searched the forum a lot. I got two solutions

1. Update the bios - done and did not help

2. Disable power saving feature for the wireless controler - still to test

Will update after 20 min what is the status of the solution.

Thanks

Okay the second option worked atleast for now. Lets see what happens if I leave it for sleep in balanced overnight.

Thanks

can you check the event logs for any errors?

try to update power management drivers.

[krishanum]

Okay guys taking the wireless controler out of the hands of the power managment system really helped a lot.

Going back to Balanced power settings for good.

Thanks

@ ag_printing

right click my computer > manage > device management > network adapters > select ethernet adapter > properties > on power management tab clear the check box for power save " allow the computer to turn off this device to save power ".
