BIOS Udate HP Systems
When do I update the BIOS?
Change the BIOS when HP releases an update for your PC model.
Note: To see what the current BIOS version is on your PC, click Start and then choose Run. Enter msinfo32 into the Open text box and click OK. Under System Summary, look for BIOS Version/Date.
To get the BIOS update, go to the HP Web site support page:
Open your Internet browser program.
Type
http://www.hp.com (or find the appropriate Web site URL for your country/region in the Warranty and Support Guide that came with your PC) into the Address box and press Enter on your keyboard.
Find the support page and follow the links to find software and driver updates.
Find the BIOS update for your PC model.
Click the name of the update file.
Read the description of the BIOS update to make sure it is the correct update for your PC, and then print the installation instructions.
Download the BIOS executable (.exe) file.
The BIOS update usually includes specific instructions for updating your PC. However, if installation instructions were not included on the Web site, follow the appropriate steps below:
Caution: Do not update BIOS unless you are sure you have the correct BIOS file for your PC, or it may cause the PC to stop working properly.
For Windows-based BIOS update files:
Double-click the downloaded BIOS .exe file (usually appearing as an icon on the PC desktop).
Accept the license terms, and then click Next.
If an Overwrite Protection message appears, click Yes to All.
Wait for the update to complete.
At the Windows Based BIOS Update window, click Yes to restart the PC.
If you see a System CMOS checksum bad error message during the restart of the PC, follow these additional steps to complete the update:
While the PC restarts, press and hold F1 for a few seconds to open the BIOS Setup.
Press F5 for a few seconds, choose Yes, and then press Enter to load the BIOS defaults. Use the arrow keys on the keyboard to choose Yes, if necessary.
Press F10 for a few seconds, choose Yes, and then press Enter to exit the BIOS Setup and save the changes.
Press Enter to confirm the save.
If you see a System Settings Change message prompting you to restart your PC, click Yes to restart the PC again.
For BIOS updates requiring the use of a blank diskette:
Insert a blank formatted diskette into the diskette drive.
Double-click the downloaded BIOS .exe file. Follow the onscreen instructions to copy the files to the diskette.
Leave the diskette in the drive and restart your PC. (To restart, click Start on the taskbar, click Turn Off Computer, and then click Restart.)
The BIOS utility starts. Follow the onscreen instructions to confirm that your PC model number is listed. This step determines if this particular BIOS update is intended for your PC.
Follow the onscreen instructions to proceed with installing the BIOS update. Do not remove the diskette until updating completes.
When prompted that the update is complete, eject the diskette. (If you do not remove the diskette, the PC continues to try to use it to restart.)
Restart the PC.
If CMOS checksum error appears, press the F2 key to bypass BIOS setup and continue the startup process.
