laptop locks up when closing the lid

[easy10]

The laptop will not respond by opening the lid. I can hear the fan running but the laptop is locked up. Only resolution is to hold the power off button for 30 seconds.

Given the date of your post, I would have expected someone to respond to it before this -- but since that has not happened, I will take a shot at it ...

This is most likely because you have Power Options set in Settings so that closing the lid puts the PC into sleep or hibernation, and while it SHOULD wakup then when you open the lid, some PCs have problems with this in Windows 10.

So, first, I would check the Power Options and set then to Nothing when closing the lid to see what that does.

If that does nothing, it could also be that FastStartup is interfering with waking from sleep.

Win10 has enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT. This is different from Fast Boot, which is a BIOS/UEFI option.

Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off.

Disabling Fast Startup might fix booting and shutdown problems.

There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F

In both cases, reboot Windows.

NOW, FastStartup is disabled.

See if that helps.
