keyboard funny - loss of ")" character

Laptops don't have room for a number pad, so they overlay the numpad keys atop the alphanumeric keys at the right end. Look at: https://www.replacementlaptopkeys.co...s/sony_vpcx_la ptop_keyboard_key.jpg (click to enlarge) Notice the 0 (zero) key at the top row has 3 characters possible: 0 (zero), right parens, and / (divide). I don't remember how it is done but there is some way to turn on the numpad characters for those keys. I _think_ it varies between laptops. On this one, it's Fn+F11, called "Numeric Overlay". I _have_ very occasionally fallen foul of it (i. e. turned it on by mistake), but (once I'd learned about it!), its symptoms are quite obvious - more the letter keys UIOJKLM don't produce their normal letters, than just the 0/) key. Good thinking, though! However, if that were the case, I would think you would get / (slash) for each press on Shift+0 that doesn't appear to do anything. I would find out what toggles the numpad and toggle it a couple times and then once more, if needed, to turn off the numpad to make sure the toggle state didn't get confused for those keys. I'm afraid that's not it. Have you yet cold booted the laptop? I don't mean shutdown into low-power or hibernate mode but completely powered off. For a cold boot, the CPU sends a reset signal to all hardware to make sure it starts in a known state. I've had hardware that got confused to what state it should be, and a cold boot gave it the reset to start at a known initial state. Yes - since this started, some months ago, I've had several of all sorts of powerdown - low-power, controlled shutdown, and uncontrolled shutdown (running on battery and not realising). [I don't _think_ I've had a _crash_ as such - I'm pretty sure I've never had a BSOD - though if the fault is in one of its more aggressive modes, actually triggering a shutdown can be hard work. But I can usually get there with the mouse (trackpad).] Do you have Sticky Keys enabled in Windows? You may not have deliberately enable it but did so accidentally. Pressing Shift 5 times in rapid succession will turn on Stick Keys. I've done that a couple time when ****ed at something and ended up hitting the Shift more than 5 times and wondering what that beep was for. No. Sometimes I do the same, but I have it set to pop up an ask. (I do have the thing that beeps when I change the lock [mainly so I know if I hit caps lock by mistake], but that doesn't change anything, it's only a beep. [May be called "toggle keys" - it was under XP - which is a misleading name for it.]) You press Shift+0 but don't get a right parenthesis character. The question is if there is a hardware fault where the keypress is not registered; i.e., no scan code for the keypress is sent. The other possibility is that some software has usurped that key combo. Keyboards generate 2 scan codes per keypress: keydown and keyup. That way, software can see if you pressed a key or released it. It has too long since I used a key scan code tool to remember what I've used. I remember running it and then I'd press and hold down a key to see what the tool said was that scan code. Then I'd release the key to see what different scan code got generated for that action. I wasn't using it to find missing scan codes but to define some key remapping. Keyboard keyboard remapping software is also a possibility for the missing scan code for downpress+0 issuing the scan code for that key combo. I've just got one - when I saw there was a NirSoft one, I got that (https://www.nirsoft.net/utils/keyboard_state_view.html) as I find his utils excellent. (I was a little surprised to find I didn't already have it as part of his suite; maybe it is too new.) I have looked at what it shows when I type shift and 0 now, and will try again next time I get _that_ fault. Thanks for the suggestion. I'd first boot Windows into its safe mode to see the problem still exists. If so, I'd try a keyboard scan code reporting tool that showed me both downpress and release of keys for their scan codes. Trouble is, I'd have to run in safe mode for a long time to see if the problem exists, as it often doesn't show up for ages. -- J. P. Gilliver.
