Suspend seems to work sometimes, but not others.

If I suspend with Fn+F4, it seems I can resume by pressing Fn.

If I let the timer put the X220 into suspend, pressing Fn wakes up my WWAN ExpressCard (since the LEDs come on), but nothing else seems to happen. The power button continues it's slow flashing, but I can't seem to bring the X220 out of suspend at all at this point. I have to hold the power button down for a few seconds to do a hard shutdown, then restart the laptop.

Note: I have the lid closed option set to "Do nothing".

The above experience might be revised, but that is the way it seems atm. I have all Windows updates applied and applied the one Update Supplement on Lenovo's site that was not already installed, KB2397190 (I checked SP1 KB's). This is with 64-bit Windows 7 Professional.

dave - have you tested without the WWAN expresscard installed?

Not yet. I'll try later when I get time.

I'm having exactly the same (or at least almost the same) issue.

I have x220 with 4Gb RAM in two slots, WiFi+WiMAX, Camera, Bluetooth, IPS screen and Win 7 Home Premium SP1.
Fingerprint, Express card and WWAN are not installed.

I have all the latest software installed.

The problem is:
Some times notebook doesn't want to wake up from a sleep state. If I open the lid (if it is closed) or press Fn button (if lid is open) notebook tries to wake up - it blink ones with CAPs lock, light WiFi LED. The power button continues it;s slow flashing. There is no HDD activity, but I hear fan noise. Screen remains black.
NB remains in this state while there is an energy in a battery, after that it start beeping (help!help! I'm out of energy ), but it still not responsive to any mouse-button movements. I have to power down the system, of course on a next boot windows complains that is was not powered down properly.
Same thing also happens (not always) if a timer wakes NB from sleep to put it into hibernate.

I'm not able to identify the roots of such behavior - It may hang both after pressing Fn+F4, or after closing the lid or after timer, i.e. any "go to sleep" actions may cause problems at resume. I failed to create a scenario which guarantee problems during resume, the behavioral is unpredictable. I can have one failure just 10 minutes after reboot and not to have them after 20 sleep-wake cycles in 2 hours.

Windows logs show no errors. I tried different power schemes, tried enable/disable "hybrid sleep", tried different USB and PCI power management parameters, still no luck.

Any advise?

An addition to my previous post.

It seems that I'm having problems with resume only after "clean" start or restart. Clean start/restart means - you start (press power button) after previous successful power down or you restarted your computer. After that, if you put you computer into sleep, it will not wake up.

"Not clean" start means - your computer did not wake up, so you shut it down with power button . On next start windows will complaint that it was incorrectly shut down and offer to boot in safe or normal mode. Continue with normal mode and after that you will not have any problems with suspend/resume till the next clean restart or shutdown.

Any suggestions how to solve this?

Interesting observation. I had a clean start yesterday with my WWAN ExpressCard installed. Later I put the X220 into suspend with Fn+F4. This morning it would not wake up. Earlier in the week I successfully resumed from suspend with and without my WWAN card installed. I'll have to see if the above is true for me.

As far as I can remember, it has always resumed successfully when the WWAN ExpressCard was not present. When the WWAN ExpressCard is installed, it may or may not resume successfully.

I should get a better handle on the behavior without the WWAN ExpressCard once I get home next month and can use the built-in WiFi. I don't use my X220 much without an internet connection.

I have read that the WWAN ExpressCard does have built in storage memory that is seen by the system as a CD drive under certain circumstances. I wonder if memory cards in general (aside from RAM) could be causing this problem if they are present?

try this...

get the X220 up and running with the WWAN card and put it to sleep.   while asleep, eject the card.   open the lid and see if it resumes.

if it resumes ok then reinsert the card and sleep/wake the system with the card installed.   if the problem remains then you know it's either the WWAN card, the driver, or something else.

regarding memory cards, i recall my X61s once wouldn't resume properly with an SD card in the slot.   a new driver for the reader was released a few weeks later solving the problem.   if you do have any other memory cards in the system, remove them and test again.

I also am having this problem with the Ultrabase Series 3 that I just got. This is without any WWAN card plugged in.

make sure you're running the latest BIOS as there was a sleep function fix in 1.15.

Ok thanks, I'll try that. I am still on the original 1.04.
