There are numerous reasons why a screen of a device might get frozen, disconnected from the Wifi, stuck on an update, or unable to proceed to desired next step. The following steps highlight a combination of either button presses and for how long to hold down the button for each model of device:

For HP Laptops:

  1. Locate the physical power button on your HP laptop.

  2. Press and hold the power button for about 10–30 seconds until the laptop turns off completely.

  3. Wait 30 seconds to allow the memory to clear.

  4. Press the power button once to turn the laptop back on.

 

For Lenovo Laptops: (2 methods)

Method 1: Using the Power Button
  1. Locate the Power button on your laptop.
  2. Press and hold the Power button for at least 30 seconds until the laptop shuts down completely.
  3. Release the button and wait a few seconds.
  4. Press power button once to turn laptop back on.
Method 2: Power + Volume Down (Some Models, e.g., ThinkPad)
