Acer Keyboard Not Working After Waking Up From Sleep
Problem: Upon wake-up (system resumption from sleep), Acer ES1-512 laptop keyboard is either non-responsive or prints multiple characters. This prevents you from logging in.
Cause: BIOS conflict with recently downloaded or installed Windows 10 Updates
Solution: You Will Need to Update (i.e., Flash) Your BIOS
Before updating your BIOS, make sure your laptop is plugged in and drawing power from AC outlet and not the battery.
- To log into your laptop, get an external USB keyboard and plug it into a spare USB port. You can get a low-cost one here on Amazon for $11.50. If you’re pressed for time, pick one up at your Staples. The Staples USB keyboard is costs about $13.30
- Optional Step: Once you’re logged in, you can determine your BIOS version by (1) right-clicking on your screen, (2) selecting run and (3) typing
msinfo32then pressing enter. This procedure pulls-up the System Information window. Scan the main window for “BIOS Version/Date”
- Go to Acer’s download drivers page and enter either (1) your laptop’s model number (e.g., ES1-512) (2) serial number, or (3) SNID. All these numbers are on a sticker underneath the laptop. Acer also offers a serial number detection tool to display the latter two options on your screen
- Use the image below for guidance. (1) Select the BIOS/Firmware tab. Most likely your installed BIOS is at a least a year older than the latest available (2) Download the latest BIOS version
- Unplug your USB keyboard
- Unzip the BIOS file you downloaded. Next navigate through the sub-folders until you encounter the executable. Now double-click and follow the prompts, if any.
After your laptop reboots, your keyboard should be back to normal
