How to Flash the BIOS in a Acer Laptop

The Basic Input/Output System (BIOS) is the software stored on your computer's motherboard. Every time you power on your Acer laptop, the BIOS performs a series of system tests to make sure everything is working properly. If you have recently installed a new hard drive or downloaded software that your motherboard can't handle, you may need to flash your BIOS to a newer version. Acer uses a special utility program that allows you to flash your BIOS without having to boot your computer from a floppy disk drive like you would with most other motherboard brands.

Skill level:


  1. 1

    Power on your Acer laptop and wait for the operating system to completely load. Double-click on the desktop icon that corresponds to your web browsing program. Click on the address bar at the top of the window and navigate to the Acer support website (see Resources below).

  2. 2

    Click on the search box and enter in the phrase "WinPhlash." Wait for the search results to appear and then click on the WinPlash download page. Click on the download link. Return to your computer's desktop and open the "My Computer" icon.

  3. 3

    Navigate to the folder where the WinPhlash file was downloaded. Right-click on the file and choose the option to "Extract to WinPhlash."

  4. 4

    Return to your web browser and navigate back to the Acer support page. Click on the link that corresponds to your physical location and then choose "Notebook" from the computer-type menu. Click on the product line and then the specific model of your Acer laptop.

    Click on the "BIOS" tab underneath the information for your laptop model. Click on the orange download button and wait for the file to finish downloading. Return to the "My Computer" window and find the file. Right-click on it and choose the option to extract the file.

  6. 6

    Open the folder you extracted and find the BIOS file that has the file extension ".whp." Click on the file and drag it into the WinPhlash folder you extracted earlier. Double-click on the WinPhlash program file.

  7. 7

    Find the heading labelled "Specify new BIOS file" and click on the "Browse" button. Click on the ".whp" file you moved into the folder earlier. Click on the "Flash BIOS" button to begin the flashing process.

Tips and warnings

  • If you accidentally download and use the wrong flash file your computer will no longer boot up properly. Be sure to save copies of any of your important files to an external source before flashing, just in case you have made a mistake.
