I was using an Acer Aspire laptop. I would type things. Often, the keyboard would give me multiple copies of the keys I pressed. For example, I might get something like this: I wwish I coould get this stuppid thingg to worrk. (Note: this was different from the problem of a sticky Ctrl or Alt key.)
There did not seem to be a single fix. That is, different solutions worked for different people, and apparently nothing worked for some people. A search (which, as I later saw, should have been a different search) led to 1 2 3 different threads, offering the following suggestions:
- Update the BIOS
- Restore Windows using the recovery CD
- Reinstall Windows without any drivers
- Use Windows update
- Update hardware drivers
- Update other software
- Replace the laptop
- Have the manufacturer replace the keyboard
- Open the computer and use double-sided carpet tape to make sure the keyboard is firmly attached to the laptop
- Type more slowly
- Control Panel > Ease of Access Center > Change How Keyboard Works (or, on my machine, Make the keyboard easier to use) > Turn on Filter Keys (click the box) > Set up Filter Keys > Turn on Filter Keys (click the box) and also Turn on Repeat Keys and Slow Keys > Set up Repeat Keys and Slow Keys > Slow down keyboard repeat rates > 2.0 seconds for the first repeated key, 0.3 seconds for subsequent repeated keystrokes. I also had to make sure the first option there, “Avoid accidental keystrokes – How long do you want to hold down a key?” was set to 0.0 seconds.
- Control Panel > Keyboard > Speed tab > Repeat delay > Long
- Control Panel > Keyboard > Hardware tab > Properties > Driver tab > Update driver
- Control Panel > Device Manager > Batteries > Microsoft ACPI-Compliant Control Method Battery > right-click > Disable
- Control Panel > Device Manager > Mice and other pointing devices > Synaptics PS/2 Port TouchPad > right-click > Uninstall
- CMD window > services.msc > ATKGFNEX > right-click > Stop
- Run antivirus software
I tried some of these suggestions. For me, the one that worked was Control Panel > Device Manager > Human Interface Devices > Bluetooth AVRCP Device > right-click > Disable. Later, however, the problem came back, although only occasionally. This time, I tried the Filter Keys option. The settings I used are shown in the list above.
The Filter Keys dialogs were a bit contrary: after going in and setting up Repeat Keys and Slow Keys as indicated above, I clicked OK and found that I was back at the previous dialog, and now Turn on Filter Keys (which I had checked) was unchecked. I had to play with this a couple of times to make it work. One unwanted side effect: the Backspace key was now very slow to repeat; to speed it up, I had to repeatedly hit it manually or else use Ctrl-Backspace.
It seemed like those changes worked for a while — first one would work, and then there were more problems, so I came back to revise this post and try another. The foregoing remarks reflect these multiple attempts to get things working properly.
Now, however, I had a new problem — one that various articles found in a search characterized as keys repeating “uncontrollably.” It would often happen that the computer would just start repeating the last letter I had used. I noticed this at first in Microsoft Word, where it happened especially with Alt key commands. Like, if I used something like Alt-C (or maybe Ctrl-C), I would find that the letter “c” was now repeating across my page. Typing anything would stop it, but then it would start again whenever I next used one of those special key combinations. C was a good example — the letter “c” had been a particular problem throughout the foregoing attempts — but it happened with other letters too. And then, after a while, it started happening outside of Word, in Windows 7. I’d try to change the name of a file, or something, and the computer would suddenly be typing “cccccc” or “aaaaa” or whatever letter it especially loved at the moment.
In response to that search, I got multiple suggestions:
- A Tom’s Hardware discussion suggested running Malwarebytes, but I already had the pro version of that, along with AVG Antivirus. I didn’t think it was a virus. As just described, it was too similar to the repeating key problems I’d had earlier. No, I felt this one was probably self-inflicted. Something about my previous tweaks had probably messed up something else.
- A Microsoft TechNet discussion offered multiple possible solutions. For some people, the problem was in the keyboard. I couldn’t rule that out. But the problem had previously seemed to go away with software solutions, so the keyboard wouldn’t be my first candidate.
- Others had a problem related to Microsoft mouse macros. There was a related possibility — that the problem was triggered by Word macros — but I wasn’t sure how to resolve that; I’d been using Word macros for a long time.
- Bluetooth dongles were apparently another source of trouble. Another Bluetooth possibility: someone said that I might have caused the problem when I disabled the Bluetooth AVRCP Device (above). I went back into Device Manager > right-click > Enable. That proved not to be the solution.
I tried turning off Filter Keys in Control Panel > Ease of Access Center — that is, undoing one “fix” I had previously implemented (above). That seemed to eliminate the really bad problem that I was just trying to fix; now I was back at square one, with just the occasional repeated key.
