x220 self-wakes from sleep

For the past week, my Lenovo x220 wakes from sleep while it is charging overnight or even in my laptop bag while it is "resting". Has anyone else had this issue? Any suggestions for a fix (other than putting it in hibernate, which would negate one of the main selling points of this laptop which is its quick start-up from sleep). Thanks.

Re: x220 self-wakes from sleep

For starters...go through device manager properties and make sure any USB connected devices are unchecked for "allow this device to wake the computer" on the power management tab.  Also make sure "wake on lan" is not enabled on the network adapters.

 

I had this problem on a T500, a X201 and a X220.  Never really figured out which device caused the problem, but once the above was done, no more problems.  It was particularly annoying when the machine would wake while the cover was closed because of the resulting excessive heat.

Thanks. I'll give it a try and report the results. Nothing like pulling a boiling hot laptop from my laptop bag!

Also Open Power manager and then click advance then in the power profile... go to advance settings then disable "Allow wake timers" for both battery and AC

Re: x220 self-wakes from sleep

Hello,

 

' suggestion will, no doubt, solve the problem, but you might want to see what operations are scheduled on the computer.  It could be the computer is waking up to perform an operation like a backup, virus scan or defragmentation.

 

Regards,

Re: x220 self-wakes from sleep

Thanks. Unchecking "wake from sleep" when on power seems to have done the trick. It doesn't exactly explain why my computer woke up in my laptop bag, but that has happened only a couple of times; whereas waking while charging has happened every night . . . but only recently :-?

Re: x220 self-wakes from sleep

I had that experienced once with my friend's laptop (non Lenovo) ... I was holding her laptop bag then I felt warm on my back. I thought the bag was think so I guess its normal for it to be warm then it became warmer. I took the laptop out and it was so hot that I couldn't hold the laptop at all.... I quickly pulled the batt out as I thought something was going to exploded .... phew ... lucky break ... =)
