Vostro V131 does not come out of sleep mode.

Hi shachicago23,

The following steps will help you in fixing the issue:

Go to Start Menu> Control Panel> Power options. Select 'Edit plan settings' and select 'Change advanced power settings'. Once the Advanced settings open, locate the Sleep option and extend it. You will see the option Sleep After, Allow Hybrid Sleep, Hibernate after and Allow wake timers. Select all the options to ‘None’ and check if the issue occurs after restarting the system.

I hope this helps.

Please let us know in case of any queries.

Thanks and regards

Hi Harish,

Thank you for taking the time to read the post and reply back.  I looked at the settings per your post and for Sleep After is set to Never and for Allow Wake Timers is disabled.  These are the only two things that I saw in sleep. 

Thanks

Hi shachicago23,

Updating the BIOS, Chipset, Notebook system software and Video driver should fix the issue. The following links will help you download the necessary drivers;

Link for BIOS: http://dell.to/R4hNCE

Please connect the Ac Adapter while updating the BIOS and do not use the system once the update is initiated and until the system restarts completely.

Link for Chipset driver: http://dell.to/WmGZHN

Link for Notebook system software: http://dell.to/RF4gBY

Link for Video driver: http://dell.to/TburlK

Before installing the Video driver, uninstall the existing Video drivers by going to Start menu> Control Panel> Programs and features. Once the programs window opens, locate the Intel Video driver and uninstall by right clicking on it.

The drivers have to be installed in the same order as mentioned above and please restart the system after every driver installation.

I hope this helps

Please let us know in case of any queries

Make sure you are using the hardware Power Button to wake the computer if a key press doesn't work. Hybrid Sleep and Hibernation require a brief press of the power button to wake the computer.

Harish, I have the same issue, did all the updates and adjusted power settings with no change.  Any other ideas?

I have a very similar problem.

If I go to sleep or to hybernate, there is a moment when the computer seems to stall and the power and wifi lights stay on. From this moment, the only thing I can do to resume is to power off by holding power button and switch the computer on again. Obviously, in case of sleep mode, I would lose all data.

I have tried to reOS the computer, but the problem comes back again.

I have also tried to reinstall drivers, with no luck either.

Any other suggestions?

Thank you

I had Windows 8 and the problems was that one time sleep works normally, but the next time I can't wake it. Installed windows 7 - can't wake from sleep all the time. Did an upgrade to Windows 8 - same thing. Will try to install fresh Windows 8 and check then. But it's really nice when even Dell can't say what is the problem..

I am having the same problem with my Vostro V131.  When I try to wake it by hitting the power button briefly, the hdd light goes on for 10 seconds, the three buttons top-right of the keyboard turn on for 5 seconds, then they all turn off.  The power and wifi lights stay lit the whole time but that's it - no video, no keyboard responses, no sounds, or tones.  I have to hard-reboot and lose my work in order to get the screen back on.  How could tech support say it is an OS problem when no other laptop at home or at my work has this problem?  I hope there is a resolution to this soon.

I hope that is the fix. I will call Dell tomorrow and ask for a new motherboard if they are open on weekends. Thank you for sharing your update.

I got my laptop to service center last week. Now waiting for new motherboard also..

Did you find a solution?  My Vostro 3550 is having the exact same problem.  Dell is working on it but has not yet solved the issue.

I was within warranty. Dell sent out a tech to my office and replaced the mother board.  The problem is fixed!

My vistro and several older machines all exhibit the same problem. I wonder could it be to no use for some time. I even removed the battery from the mother board as suggested on some forum. I have switched on ind off removed cables tried different monitors but to no avail. Just stuck in power save mode and no way to get out of it this seems to be a common problem in forums but dell doesn't seem to have an answer.
