Fix #2: Reset Your BIOS
The second fix here is another sort of "reboot" of things, but it's a bit more in-depth and complicated. For this one, you'll be resetting your Basic Input/Output System (BIOS), which should erase any faulty code or software malfunction that happened while you were using your keyboard. To do this on an Inspiron laptop, there are two ways:
- The first way is easier, and requires you to start by shutting down your computer and removing the battery. Make sure the laptop is also not plugged in.
- Next, open up the lid of your computer and hold down the power button for four to eight seconds. Despite not having a battery in, this should reset the motherboard, and therefore your BIOS.
- Place the battery back in and then start your computer back up. When it gets to the desktop, open up a word processor such as Microsoft Word or Notepad and attempt to type. If you can now, you're back in business!
- The second way to do this is a bit more complicated, but also within reach if you're a computer novice. Start up your computer as normal, and when you see the BIOS splash screen, hit the F2 key until it opens the BIOS menu. Note: If you fail to hit the key in time, you'll need to restart your laptop and try again.
- Navigate your way around the menu until you find the option that says "Load Defaults". It should be located on the bottom of the screen, and can be activated by pushing the "9" key. This is the option you want to click.
- Click the "Save" option, accessed by hitting the "F10" key. Follow the instructions, and then exit set up.
- After it completes, let your laptop restart and then try your keyboard again!
This should have everything back to normal. If not, try the last fix.
