To reprogram an Acer laptop, you usually change one of three things: how keys behave, how the BIOS or UEFI firmware starts the machine, or how the operating system handles startup and input. Most people need only a software change, such as remapping a key or adjusting a setting, and can do it in under 10 minutes. Firmware changes take longer and carry more risk, so this guide covers both and tells you when to stop.

Step 1: Identify What You Need to Reprogram

Start by naming the symptom. A key that types the wrong character points to keyboard mapping. A laptop that skips the right drive at startup points to boot order in the BIOS. A function key that does nothing may need a Fn-key setting or a driver update. Knowing which category you are in saves you from changing the wrong setting. If the laptop will not power on at all, check the troubleshooting guide on Laptop Not Turning on Acer: 7 Fixes to Try First (Step-by-Step) before touching firmware.

Step 2: Remap Keys and Function Behavior

For most key problems, you can change behavior without touching firmware.

  1. Open Settings, then Time & Language or Devices, and select Typing or Keyboard options to confirm the input language is correct.
  2. For function keys, look for a Fn Lock setting, often toggled by pressing Fn with Esc. This switches between media controls and F1 to F12.
  3. To remap individual keys, use a free utility such as PowerToys (Keyboard Manager) from Microsoft. Choose the source key, then the replacement key, and apply.
  4. Restart and test the key in a text box before relying on the change.

If a key stops responding entirely, the problem may be hardware. Our guide on Volume Button on Laptop: Where It Is and How to Fix It explains how to tell a software issue from a stuck or broken switch.

Step 3: Change Boot Order and BIOS Settings

BIOS (or UEFI) changes control how the laptop starts. Use them to boot from a USB recovery drive or to set the correct drive priority.

  1. Save all open work and shut the laptop down completely.
  2. Press F2 immediately after powering on (on many Acer models, Del also works). Some models use F12 for the one-time boot menu.
  3. Use the arrow keys to open the Boot tab. Move your preferred device, such as a USB drive or the internal SSD, to the top of the list.
  4. Press F10 to save and exit. The laptop will restart with the new order.

Leave settings you do not recognize alone. Changing secure boot or virtualization options without knowing their effect can stop the system from starting.

Step 4: Update Firmware and Drivers Safely

Acer publishes BIOS and driver updates on its official support site. Use the serial number or model name to find the right file for your exact machine. Keep the laptop plugged into power during the update, because an interruption during a firmware flash can make the machine unbootable. Driver updates that fix keyboard or touchpad behavior are safer and often sufficient.

Quick checklist before you start

  • Back up important files to an external drive or cloud storage.
  • Note the current BIOS version (shown in System Information).
  • Keep the charger connected during any firmware step.
  • Write down the original setting so you can revert it.

Common mistakes

  • Downloading a BIOS file for a different Acer model. Always match the exact model number.
  • Interrupting an update by closing the lid or unplugging the charger.
  • Changing several BIOS options at once, which makes it hard to find the cause if something breaks.
  • Assuming a key problem is software when a wedged or loose keycap may be the real cause.
  • A USB flash drive is useful for creating a recovery or boot drive before you change any firmware settings. View on Amazon
  • A small keycap puller helps you check for debris under a sticking key before assuming a software fault. View on Amazon

FAQ

Will reprogramming my Acer laptop erase my files?

Remapping keys and changing boot order do not erase files. A BIOS reset to defaults also leaves your data intact, but a fresh OS install or certain recovery options will. Back up first to be safe.

How do I know which BIOS version my Acer needs?

Check the model number on the bottom case label, then match it on Acer’s support page. Only install a BIOS file listed for your exact model.

Can I undo changes I made in the BIOS?

Yes. Most BIOS screens offer a Load Setup Defaults option, usually on the Exit tab. This restores factory settings without touching your files.

Conclusion

Most Acer reprogramming jobs come down to adjusting key behavior, boot order, or driver and firmware versions. Work from the least risky option upward, and document each change. If a firmware update fails or the laptop will not start afterward, consult an Acer-authorized technician.
