A part of the numeric keypad is not working anymore. Solved

Question

Hello, I have had an HP Pavilion for several years, equipped with Windows 10. My computer has always worked very well until a few days ago when several keys on the numeric keypad stopped responding (4, 5, 6, 3, 0, - and *).  I tried to update the keyboard driver, but there was no change. I also uninstalled and then reinstalled the driver without success.  Do you have a solution for me?  Thank you for your help.  Best regards.

Hello,  What kind of Pavilion is it..? It’s likely that your keyboard has a line in the X Y matrix of the keyboard that's malfunctioning because those are neighboring keys.. -- You can troubleshoot by using the uppercase alphabetical keys.. -- You might have a key that’s stuck in the pressed position... or something foreign under the keys, like coffee spills, or soda, or something else inside... -- Otherwise, you may need to consider replacing the keyboard... That’s it for a first approach.

Hello, Thank you for your response. This is a HP Pavilion 17-E015SF from 2015. Indeed, now I have no choice but to use the alphabetical keys. As for the keyboard, no key is stuck and no debris has fallen on it. I am relatively meticulous with my belongings. Could this issue be due to wear and tear on the hardware?  Best regards

Why do you say "I no longer have the choice to use the alphabetical keyboard" when, on the contrary, you have no choice but to use the alphabetical keypad...  -- Yes, in this case it's a form of wear, probably linked to the sustained use of the numeric keypad. We can also talk about reliability, and some have more luck than others in the game of the law of numbers...  Here are some keyboards that could fix your case https://www.touchedeclavier.com/2919-clavier-pc-portable-hp-pavilion-17-e004sf-17-e015sf-17-e018sf-17-e019sf.html  https://www.cdiscount.com/informatique/clavier-souris-webcam/clavier-fr-azerty-hp-pavilion-17-e004sf-17-e015sf/f-1070215-hex4896200490316.html  https://topclavier.com/claviers-hp-17-e-pavilion-series/22679-clavier-portable-hp-pavilion-17-e004sf-17-e015sf-17-e018sf.html  https://www.ebay.fr/itm/Clavier-Fr-AZERTY-HP-Pavilion-17-e004sf-17-e015sf-17-e018sf-17-e019sf-17-e020sf/151824633120?hash=item2359740d20%3Ag%3Ar7kAAOSwpDdVS5oW  There are many keyboards on the web... but many are QWERTY while for France, they should be AZERTY... a detail not to be neglected...  You can also test an external keyboard, connected via USB, to check if it's indeed the problem and/or to troubleshoot in the meantime...  There you go, I think I’ve covered everything...

Thank you for your help; Indeed, it was a phrasing error :-) I also found a tutorial online that explains how to replace it. What do you think?

Yes, certainly, it's not very difficult, it can be done in 15 minutes... let’s say for less than €30. Be very careful with the ribbon cable, do not damage it, otherwise it's game over.

Hello.  Just passing by . . . Indeed, as Jeannets said :-), be very careful during disassembly. On almost all PCs, the cable is held by a black clip that needs to be flipped back before pulling on the cable. If this black clip breaks, the entire connector will need to be replaced! And it's soldered onto the motherboard, so good luck with that, especially trying to find the exact same connector.  Good luck . . . See you later  -- There's no point in rushing; you have to leave on time . . .

Hello everyone,  Thank you for these valuable tips. I will try connecting an external keyboard first to make sure it's indeed the laptop keyboard that's having an issue. I will keep you updated on the result, of course.  Thanks again for your help.  Best regards.
