Revolve 810 G1 Keyboard skips characters when typing

Question

Hi all, Just got a brand new HP Revolve 810 G1 tablet/laptop (12GB memory 256GB SDD). Things are otherwise smooth, but there is extremely annoying problem of keyboard dropping / skipping / losing some of the characters when typing. It appears randomly, not any specific keys or combos. Up till now in this post it has skipped about 10 characters. It doesn't require fast typing, even in the Win 8 start-menu, when searching for an app and then hitting enter to start the app, it might not react on the enter press. This is just an example, letters are missing from anywhere where I type. I type quite fast and know that I am hitting the correct keys. Disabling the touchpad does not help, so it is not that I would accidentally touching it during typing. I have updated BIOS, restored OS to factory state (HP Full Recovery), switching to English OS localization, installed all Windows Updates - no help. This makes working a pain, it's not feasible to chat or type document when you have to backspace all the time to fix the mistakes that you did not make. HP Support Assistant is not finding any more updates, product number is H5F12EA#AK8,WIn 8 Pro 64-bit. I have installed a 8GB SODIMM under the back cover, replacing the included 4GB chip. Will run a memtest overnight. Anybody seeing the same?? tonttuz

Welcome to the HP forum, Tonttuz. If you have adjusted the keyboard speed properties, updated the drivers, and done all the usual, thenIt could be keylogger malware - run a deep scan and make sure you are the only watching what you typeIt could be another program slowing down the system and interfering with your input - check the Task Manager and look for "hogs" -- programs that are running with a high cpu / network / disk consumption and stealing resources.It could be hardware - the system is new, but its construction may not be flawless -- Call HP=====================================================================================It could be that the drivers, though updated, are not being read from disk - instead they may be tangled in the memory and not being read properly. You might consider, without any grand hopes of success, applying a Forced Reset: Forced Reset flushes out the persistant boot-to-boot software and driver instructions from memory and forces the system to go back to the disk to read the software and drivers from the disk Operating System. Forced Power Reset Performing a Hard Reset or Forced Reset The Power Reset cannot tell the difference between drivers - it does not analyze a driver or software program before applying it.  It assumes all the drivers and software on your computer belong there. This is a Driver Reset; this is NOT the Windows 8 Reset that installs the Operating System.  This procedure does not wipe out your files nor does it destroy your Windows setup in any way. EXAMPLE:If the driver software on disk is incorrect or if the driver software is corrupt, it will still be incorrect or corrupted after the Reset.If the driver INSTRUCTIONS are tangled, messed up, or there are bits missing from those instructions, then the Reset may fix the problem. Why a Power Reset works to fix some issues: The Power Reset does not install anything on your computer, the Power / Hard Reset does not remove programs or personal data from your computer, and the Power Reset does not change the settings on your computer.  Your data and programs remain as they were before the reset was applied.  The Reset drains out the old program instructions from the memory and forces the computer go to the on disk Operating System to get new instructions. Why a Power Reset might Not Work:If the issue is more than just entanglement, if the "good instructions" on the computer are not good enough -- that is, you need an update, a new driver, or there is a problem that cannot be "untangled", then the Reset will not work. If there is a hardware problem the Power Reset will not work.==================================================================================== If you want to contact HP directly, you may use the following: Contact HP - Worldwide Contact HP – USA - Phone Assistance  Warranty Required – USA and CanadaUSA – Contact HP // Self-Help – Email - Chat  Good Luck!
