The quickest way to restart your HP computer

The fastest restart on any HP computer is to hold down the power button for a full ten seconds until the screen goes black, then press the power button once to turn it back on. This is a hard restart—it cuts power when ready without saving anything—so use it only when your computer is frozen or unresponsive.

If your HP is working normally, use the menu restart instead. Click the Start button (the Windows logo in the bottom left corner), then click the power icon, then select Restart. This takes about 30 seconds longer but closes your programs safely and saves any unsaved work that Windows can recover.

Key Takeaways

  • A normal restart through the Start menu takes 1 to 3 minutes and closes programs safely; a hard restart (holding the power button) is when ready but should only be used when the computer is frozen.
  • On a frozen HP, hold the power button for a full ten seconds until the screen goes completely black, then press it once to restart.
  • If your HP will not respond to the power button, unplug it for 30 seconds, then plug it back in and press the power button.
  • Restart your HP once a month to clear temporary files and keep it running smoothly, or whenever it feels slow or programs are crashing.

How to do a normal restart through the menu

Open the Start menu by clicking the Windows logo in the bottom left corner of your screen. A menu will appear with a list of programs and settings.

Look for the power icon—it looks like a circle with a line at the top—usually in the bottom right corner of the Start menu. Click it. A small menu will pop up with three options: Sleep, Shut Down, and Restart. Click Restart.

Your HP will close all open programs (Windows will ask you to save any unsaved work first), then the screen will go black. The restart takes 1 to 3 minutes. You will see the HP logo, then the Windows logo, then your desktop will reappear. Do not turn off the computer during this time.

How to force restart a frozen HP computer

If your HP is completely frozen and will not respond to mouse clicks or keyboard presses, use a hard restart. Locate the power button on your HP—on a desktop it is usually on the front of the tower, and on a laptop it is on the side or above the keyboard.

Press and hold the power button for a full ten seconds without releasing. The screen will go black and the computer will shut down completely. Wait five seconds, then press the power button once to turn it back on. The computer will restart normally.

A hard restart does not save your work, so any unsaved documents will be lost. Use this method only when the computer is completely unresponsive. If your HP freezes regularly, restart it once a week through the menu instead to prevent the problem from getting worse.

What to do if the power button does not work

If pressing the power button does nothing, your HP may have lost power or the button itself may be stuck. First, check that the power cable is plugged firmly into both the back of the computer and the wall outlet. On a laptop, make sure the power adapter is plugged in and the charging light is on.

If the cable is connected, unplug it from the wall outlet and wait 30 seconds. This drains any remaining power from the computer's internal battery. Plug the cable back in, wait a few seconds, then press the power button. Your HP should start up normally.

If the power button still does not work, the button itself may be damaged or stuck. On a desktop, you can use the reset button instead—a small button near the power button that will restart the computer. On a laptop, you will need to take it to a repair shop, as the power button is built into the case.

Why you should restart your HP regularly

Restarting clears temporary files and memory that build up while your computer is running. Over time, these files slow down your HP and can cause programs to crash. A restart once a month keeps your computer running smoothly and prevents problems from developing.

Restart your HP when ready if it feels slow, if programs are crashing, or if you notice error messages. A restart often fixes these problems without any other action needed. If the problem returns after a restart, the issue is likely something else—a virus, a failing hard drive, or a program conflict—and you may need to take your HP to a repair shop.

The difference between restart, sleep, and shut down

Restart closes everything and starts the computer fresh. It takes 1 to 3 minutes and clears temporary files. Use restart when your computer is slow or programs are crashing.

Sleep puts your HP into a low-power state where the screen goes dark but the computer stays on. It wakes up in seconds when you press a key or move the mouse. Use sleep when you are stepping away for a few minutes or an hour. Sleep uses a small amount of power, so your battery will drain slowly on a laptop.

Shut Down closes everything and turns the computer completely off. It takes about 30 seconds. Use shut down when you are done for the day or before unplugging your HP. Shut down uses no power at all.

Frequently Asked Questions

How long does an HP restart take?

A normal restart through the menu takes 1 to 3 minutes from the moment you click Restart until your desktop appears. A hard restart (holding the power button) is when ready, but the computer still takes 1 to 3 minutes to start back up. The exact time depends on how many programs you have installed and how much data is on your hard drive.

Will restarting delete my files?

No. A normal restart saves your files and closes programs safely. A hard restart (holding the power button) may cause you to lose unsaved work in open documents, but your saved files are not deleted. Your computer's hard drive is not affected by either type of restart.

Can I restart my HP while it is updating Windows?

No. If Windows is installing an update, let it finish before restarting. Interrupting an update can damage Windows and make your HP unable to start. If an update is taking longer than an hour, your HP may be frozen. Wait another 30 minutes, then use a hard restart if it still has not finished.

What should I close before restarting?

You do not have to close anything. When you restart through the menu, Windows will ask you to save any unsaved work in open programs, then close them automatically. If you use a hard restart, close your programs first to avoid losing unsaved work.
