Unusual behavior when using "Shift" combined with other keys
Unusual behavior when using "Shift" combined with other keys
Hi everyone. I’m facing an unusual issue that’s been ongoing for some time. My laptop is still from about three years ago and hasn’t suffered any damage. Around a year after buying it, the “Left Shift” and “Right Shift” keys only responded with certain letter keys—especially uppercase ones—and not others. It gets even more confusing: the Right Shift key works with letters like W, X, C, while the Left Shift key doesn’t seem to work with Z, A, Q, and so on. Interestingly, they sometimes both stop working at random, or they’ll suddenly return to functioning after a reboot. Another odd point is that some keys need both shift keys pressed together to type uppercase letters. Despite having updated drivers, this problem persists only for these two keys. I’ve also tested an external keyboard, but the Left Shift still only works with everything except Q, S, D, J, K, and L. Update: using a different keyboard helped, though the Right Shift now functions normally across all keys. Thanks for your help!
Is the problem continuing when using an external keyboard? If not, internal heat from the laptop might have harmed the keyboard connections. I’d check if your HP has a customer support line and/or consider replacing the keyboard. If available, it could be a software issue—generally fixable but needs more details.
Thank you for your feedback. From my own experience, it seems both shift keys aren't responding with letter keys possibly due to a power brick issue. I'm unsure if the connection was incorrect, but I tried unplugging and replugging it later and the problem disappeared. Unfortunately, the issue remains unresolved, and it feels like it's set in an unexpected way.
