No response after entering sleep mode

Hi

 

I have a T530 with Windows 7 Pro x64.

 

I am getting a problem i had on my old computer with both Windows 7 & 8 installed again on this new lenovo computer. I really need to trust stanby, so i can count on it starting again if i close the lid or in another way sends it into stanby mode.

 

The problem is, that it sometimes (i dont know why) doesn't go to sleep mode when i close the computer/press the sleep button/press the powerbutton on dock.

 

It just gets blank screen (screen is turned off), fans and light on. Mute button works. I see the wireless icon on, and the HDD activity icon blinking a bit, but not much. This time i pressed random keys to see if i could wake it again from this blind stage, but i dont think it did anything. I saw a short blue blink before it turned off, crashed. I think i got a bluescreen, but there is no report from windows about it.

 

I've searched Google, but all problems was blank screen AFTER it had been in stanby, this is when it goes INTO stanby.

 

Any idea how i can stop this problem? Does i have to provide more data for a solution? Maybe a list of programs installed will help?

 

Thanks in advance!

Hi,

I have the same problem with my T420. Yesterday I reinstalled the OS Windows 8 and the problem persists.

Thanks

Re: No response after entering sleep mode

I do only have a 8GB in the slot under the keyboard, configured by Lenovo.

 

It does once a week maybe twice, but i havent had this computer for long.

 

The problem is, that i dont know what makes it comes. Last time i just had saved a document on word and closed the computer shortly after. The previus time before that was sometime near a defragmatation. But i also had it without any disk activity.

 

But it is tends to come if i close it shortly after doing something on my computer. On my previus computer i traced it to the ram. If i secured i not used all the ram, i was pretty sure it would go stanby, but not completely.

 

Now what?

Re: No response after entering sleep mode

I'm taking a wild guess that it may be related to the sporadic shutdown/failure during standby of the W520, although I haven't heard it reported for a 14" machine. The fix is quick and worth a try though:

- Take off the RAM door on the bottom (while the system is off and unpowered).
- Inspect the metal flaps on its periphery and gently bend them to stick out more so it makes better contact with the chassis to better ground it.

Re: No response after entering sleep mode

Thanks for your guess, but i do not see why it should be it. It mostly goes into stanby normaly. I think it is some kind of software problem, but i dont know what software that could do it.

 

Also i only had this computer a few weeks. I think it is unlikely it could happen on that short time.

 

I might try it, but it will requre to open my computer and take the RAM out of it. I would like to see if the problem could be somewhere else, before i do that.

Could it be Dropbox uploading a file?

Re: No response after entering sleep mode

It might be? I know if I leave Folding@Home running, it'll refuse to go into standby (screen goes blank then comes back to the lock screen). But it's very consistent when it does this, and is very consistent in going into standby properly after turning it off.
