Lenovo G500, can't start+doesn't wake up from sleep mode

So, as I stated it in the subject, I can'tstart it. Well it's not the whole truth, since I can start it with the power button code (you know, that take of battery and AC cable, ten times the power button, power button for 30 sec, put power back, and works like a charm), but it's kinda annoying, that I always need to use this method. So I'd like to ask if there is any solution to make it work normal. Another thing is in the subject too, well that's just what I said in the subject, laptop doesn't wake up. Is there any solution for this?

OS is Windows 10, and I use the laptop since 2014 February.

Re: Lenovo G500, can't start+doesn't wake up from sleep mode

Hi Peter,

 

Welcome to Lenovo Forums.

 

I have a few questions to gain more clarification about your issue: FIrstly, does the issue arise when you attempt to wake the system from sleep while plugged in, or is it an issue where if you put it to sleep while plugged in, you will not be able to wake the machine?

 

Also, do you use Windows for the power settings or are you using Lenovo Power Manager?

 

Hope this helps. Let us know how you get on.

 

Regards,

Shashi

Hi,
To your first question, both of the options is true. But the second one has a bit of more truth in it, when I put it to slee it's almost always plugged in, but at waking up, in the 40% of time it's running from battery.
And regarding the socond one, I use Lenovo Energy Management.

Hi Peter,

 

Just as a test, could you uninstall Lenovo Power Manager and then try to put the machine to sleep? Make sure you restart the machine after uninstalling Power Manager. If the machine goes to sleep as it should, then the issue obviously lies somewhere within Power Manager, which could possibly be remedied by a reinstallation of the software.

 

I would recommend giving these steps a shot and see anything changes with the removal/reinstallation.

 

Good luck!!

Regards,

Shashi

Re: Lenovo G500, can't start+doesn't wake up from sleep mode

Hi,

After your answer I just realized that while you was talking about Power Managment, I said Energy Managment. So I tried to install Power Manager, after it suggested to restart the laptop I did it. It couldn't restart, just went off but didn't came back to life. After I somehow switched it in (tried to switch it on, plenty of times, and after half an hour it worked). Power Manager wasn't installed I couldn't see any clues of it. So now I'm sure I'm using Windows as power managment, since I'v uninstalled the Energy Managment stuff too (that neither solved the problem), and I can't install Power Manager (becouse of that can't restart thing). So my power is now managed by Windows (but still doesn't really work).

And we're back...
