Laptop freezes after waking from hibernation or sleep?

for the past few days, when i wake up my computer from sleep and hibernation mode it'll freeze and the only way tp get it to work is to hold the power button.

just for your information, i recently updated some drivers but i will try to delete the new power management driver and go back to the old one

Edit: i cannot roll down battery driver for some reason

Answer this question I have this problem too

Is this a good question?

I had a similar issue myself and I tracked it down to my wireless drivers, and I have seen the same issue on several other laptops as well. My only solution was a workaround though, using the function keys to turn off the wifi when putting it to sleep, and turning it back on upon startup. But you are on the right track, it is most likely a driver issue as you have stated.

Does it give you an error when you attempt to roll back the power management driver?

Same issue here (caused by the Dell O2 card reader driver A04).

Edit: the A02 revision of the above driver causes the same issue.

This issue occurs in Windows 7, 8, and 10.

I fixed it by uninstalling the Dell O2 card reader driver Rev A04 and then installing the Lenovo equivalent driver from here:

This covers Dell Models




And probably any other Dell laptops with the O2 card reader driver.

Try changing the Power Option setting for your HDD because there's a part there where HDD can turn off and that's causing this problem with your laptop. Please try and follow these steps
