Another way to check for hardware issues is to review the keyboard itself for physical damage. Look for broken keys, stuck keys, or any signs of wear and tear. It’s also a good idea to inspect the keyboard connection internally if you feel comfortable doing so. If the internal keyboard has visible damages or if none of the troubleshooting methods work, it may need to be replaced, and seeking professional repair services is advisable.
Are there any key combinations I should try to fix keyboard issues?
Yes, there are key combinations that may help in resolving keyboard issues on your Dell laptop. One common combination is the “Fn” (Function) key along with the relevant function key, such as “F1,” “F2,” or “F12,” which can occasionally toggle keyboard settings.
