Windows 7: Lenovo ideacentre B320 on Windows 7 keeps going into sleep!!!

Lenovo ideacentre B320 on Windows 7 keeps going into sleep!!!

How silly is that when you buy a new computer state of the arts blabla really cool and then every so many minutes its shuts down into sleep mode with no appeared solution within the normal setting. I do a lot of playing around with photo and video editing and that makes me watch slide shows a lot to check how it is going to look only to find my screen going black over and over again grrrrrr or watching internet tv.....what a crap. Anyway I am a complete know nothing when it comes to computers but your instructions were so easy and clear that even I solved it. THANK YOU SOOOOO MUCH for your effort to put this online!

Kindest regards.

It is still going to black screen grrrrr. Although the sleep option has turned grey as you said it would after restarting this computer my first try to watch a slideshow was cut short after it went back onto a black screen only after about 15 photo's. What to do next? any suggestions? Thanks.

Even worse it started going into sleep while I was browsing the net as well.

While I was using skype trying to recieve help to solve this problem I let a slideshow run as I did before but no sleep mode was activated. Skype running at the same time obviously kept the computer from going into sleep mode.

Check the power options, nearly all new computers are default to go into sleep mode as an energy saver. You can disable these in Start -> Control Panel -> Power Options -> Change when the computer sleeps

Already tried that many time over

Thank you for your reply. Your suggestion was the first thing I have done and repeatedly tried over the last few days with no change. I even followed instruction found online on how to disable the sleep mode but I am told that this only disabled the sleep mode choice and not the sleep mode itself.

Please anyone out there who has an idea to solve this annoying problem please feel free to bring forward further suggestions.

Kindest regards.

If you have disabled sleep mode from happening and it continues to go into sleep mode, then Lenovo have probably installed software on your PC that will put it into sleep mode regardless of what setting you change. Did your PC come with default software already installed on it??

Thank you

Thank you for you reply.

Yes the computer came ready to go with a recovery disc and a VERY small

It is a great computer, just love it, but this going into sleep mode drives my patience through the roof. I have bolted the screen up against the wall....just in case....hahaha.

Seriously it would be great if you or anyone else for that matter would be able to help me solve this.

I think you need to check Lenovo's Energy Management setup, which if I'm not mistaken, takes precedence over Windows Power Management.

Thank you for your reply. I followed your links but still no change to my computer going onto a black screen whenever It likes to do so. In the Lenovo BIOS setup utility settings I can see : ACPI standby mode [S3 (str) ] but this is grey and not accessable to me. This is as close as I can get so far in trying to make any changes within the Lenovo system so far. No matter what kind of settings I use in Windows, screen keeps going onto black after I have not touch my mouse or screen for a few minutes which happens a lot when I watch slideshows, video, internet TV, TV or read a book on my computer from the Kindle store? So, please someone out there who has come across this problem before feel free to share how you changed it. Thank you. Kindest regards, Bianca.

Screen keeps going black!

My new computer screen keeps going onto black. I have a Lenovo since 3 weeks and from the start it keeps going onto a black screen. Now matter what I have tried so far it keeps doing it which is very annoying and makes working on this computer almost impossible. I have posted a treat before within this forum to so far without any success. I came across information which said to go to start type in search: cmd then enter then type in powercfg-a enter and I get the following message:

"powercfg-a! is not recognized as an internal or external command, operable program or batch file.

The computer is running windows 7.

I tried all the power setting, changed it many times over. REstarted the computer many times over but no change.

Screen goes black

I have a new Lenovo running windows 7 and I have the same problem my screen keeps going black as if I am inactive. editing and watching movies is impossible without having to touch my mouse or the enter button every few minutes. I have already tried all the power setting but it has not made any change so far. Using the computer becomes a very challenging task at the moment testing my patience to the limit. Any idea? I have already tried typing in CMD in the search and then powercfg-a but instead of showing me what is causing the computer to go to sleep I get the message that "powercfg-a" is not recognized as an internal or external command, operable program or batch file. Would be great if someone out there could help me solve this. Thanks.

Try typing powercfg -lastwake this will tell what last woke your PC if it has been going to sleep. Note the space between the "g" and the "-".
