Resetting the power and power supply of the laptop (a power reset) may fix problems like:

- Laptop does not turn on,
- Windows does not respond,
- black display,
- keyboard or keys do not work,
- audio controls do not work, etc.

Follow this guide to reset your laptop's power and power supply to possibly fix such issues.

Resetting the power will erase all data from the computer's cache an memory without deleting any personal data and it will restart all hardware components.

If your laptop won't start or doesn't boot properly and emits beeps and/or LED blink codes, here you can find possible causes and solutions.

Hardware driver, firmware updates and BIOS updates from the laptop manufacturer are very important. Use HP Support Assistant, which is pre-installed on all new HP laptops, to do this easily.

Install all updates that are offered (optional, recommended and critical) and check again after reboots for further updates until no more are offered.

Data loss can happen at any time and for various reasons. We therefore recommend that you back up your data regularly.

Windows offers three different ways to make a backup:

• Cloud Sync/Backup with OneDrive: This covers to selected data, Windows settings, MS Store apps, etc.
• File History: This covers selected data, and is meant to continuously save things you edit as backup versions.
• System Image Backup : This covers the entire Windows system including installed programs and data. It takes a snapshot of your entire system.

The file version history and the system image are something you make on an external hard disk.

A backup with OneDrive goes to the OneDrive Cloud (you need a One Drive subscription via Microsoft 365).

If a problem cannot be resolved easily, or to rule out a software problem, resetting Windows is often the most efficient solution.

When you reset Windows, it is reinstalled. You can choose whether you want to keep or remove your files when resetting.

• Reset Windows
• Perform an HP System Recovery

Recovery media can be used to bring your laptop back to its factory settings:

• HP Cloud Recovery (USB recovery media download - not supported for all older models)
• Order recovery media for HP laptops 
• Create recovery with Windows
