The new ACT and LP circuit has additional key debouncing in its firmware, because the original HP debouncing is executed much faster than normal and doesn't work properly, but it will not repair any keyboard contact issues. If I would increase the debouncing time, then the key response would become worse. Use DeOxit Red contact cleaner to improve the contacts. This helps in most cases. Bernhard That's one small step for a man - one giant leap for mankind. |
