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.

• Open Control Panel (or use the search box on the taskbar).
• Search for Power Options – this will open the dialog box.
• 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’.
• Change the behaviour under ‘On Battery to Hibernate’ and then save your changes.
