přestaly mi fungovat tlačitka na touchpadem notebook hp elitebook G5

Mel jsi nekaou aktualizaci OS ?
V pripade ze MS preinstaluje vychozi ovladac za MPC (Microsoft Precision Touchpad) ma to stejny dopad, touch pad funguje ale tlacitka prestanou reagovat.

Otevri : Nastaveni -> zarizeni/periferie -> Touchpad -> co tam vidis, "Precision Touchpad" ? Jestli ano, tak je chyba jasna.
Jak to vyresit ? Preinstaluj, stahni si treba driver ze stranky vyrobce a preinstaluj ho na spravnou verzi.

tyjo nikde to nemuzu najit nic takove v nastaveni najit

vypis i v: devmgmt.msc

Tak tak.

Bud pres klavesovou zkartku [WIN + R] a vlozit "devmgmt.msc", nasledne najit polozku mys → pravy klik info kde by jsi mel videt jaky ovladac pouziva, nebo na misto devmgmt.msc se muzes do spravce zarizeni dostat pres pravy klik na policko START (Windows).
(popripade seznam aktualizuj klikem nahore na ikonu monitoru s lupou)

V pripade ze nahodou mys nevidis, nebo neni v seznamu, zkus v horni liste povolit zobrazeni skyrych komponentu. Klik na Zobrazit → Skryta zarizeni :

You can find detailed Bibb tax records that offer transparency on various proceedings and documentation. These tools streamline research and help you stay informed about important dates and outcomes.

Try updating your Synaptics or ELAN touchpad drivers via HP's support site, as outdated drivers often cause button issues. You can also disable and re-enable the device in Device Manager to reset its functionality. For supplementary reference resources, check Fayette court information that may offer useful documentation templates. Additionally, ensure Windows updates are current, as patches sometimes fix hardware compatibility glitches. If problems persist, HP's diagnostic tools can help identify deeper hardware concerns.
