Sometimes your laptop can spring into life while still in your travel bag. This can drain the battery. Here’s how to prevent it from happening. On a PC running Windows 10, change the behaviour of the system so that closing the lid causes the system to hibernate instead of sleeping. This means that the system won’t start-up until you instruct it to.

1-Open Control Panel (or use the search box on the taskbar).

2-Search for Power Options – this will open the dialog box.

3-From the list of links on the left, click ‘Choose what closing the lid does’.

Every modern laptop should have the option to define settings for ‘When I close the lid’.

4- Change the behaviour under ‘On Battery to Hibernate’ and then save your changes.
