Num lock turning on whenever i press S

Whenever i press the "S" key on my keyboard, Num lock turns on. Not only that, But when i press num lock, The S key is pressed. Plus, when i press f when in num lock, 0f turns up. When i press \ in num lock mode, 4\ turns up .When i press \ in normal mode,
\goes behind the current key. In addition, when i press 3, 9 turns up. If anyone would have the answer to this , it would be great.

 

Laptop keyboard pressing multiple keys

Hi! So basically, I was using my laptop and shut it down as I needed to go somewhere. I came back and turned my laptop back on and the keys were messed up (pressing backspace presses backspace and /, pressing P presses left bracket and P, pressing caps lock
presses W and caps lock, etc.) I tried the num lock solution, uninstalled keyboard drivers and restarted, tried changing layout of keyboard and nothing worked. Any help would be appreciated, thank you!

Press Shift Key to turn off Caps Lock

Actually, I get asked this quite a lot

There is, however, a very good reason to prefer this (old) „Typewriter Caps lock“-behavior over the new default, and it's simply this: if „Press the SHIFT key“ (instead of „Press the CAPS LOCK key“) is selected, then the behavior of „Caps lock“ changes from being a „toggle key“ to being a key that can only be used to turn „Caps lock“ on – to turn „Caps lock“ off, one has to press (either) one of the Shift keys.

This can be advantageous for touch typists, who are used to writing long passages of text without looking at the keyboard, and especially so if they're (C/C++) programmers, who may still regularly find themselves typing in variable names of CONSTANTS_IN_UPPERCASE.

That's because, if Caps lock is not a toggle key, it's not necessary to keep track of its current „toggle state“ in your head:

• If I want „Caps lock“ to be on, I can press CAPS as often as I like. If it happened to be enabled already, nothing changes; otherwise, I can be sure it's enabled afterwards.
  
  
• If I want „Caps lock“ to be off, I can simply press SHIFT

This sounds like a hypothetical advantage, but it's not. I work as a programmer, and I often find myself typing in code like the following:

/* Some debugging code; will only be included in debug builds: */
#if defined _DEBUG

Afterwards, I may pause a little, to think about the code line I would like to type in next. Now, if „Caps lock“ is a toggle key, I may (once I decide to continue) be unsure if I actually remembered to turn „Caps lock“ off at the end of ‘_DEBUG’.

Did I? Did I not? – The only way to be sure, is to look.

This is not so, if the „Press the SHIFT key“ behavior is enabled. If unsure, I can just press SHIFT once, be sure of the set state, and merrily continue may way.

That, for me, is the single most important reason to prefer the „Press the SHIFT key“ setting. Also, interestingly, this used to be the default behavior in the old days … at least, until Microsoft decided to ditch Windows 9x in favor of Windows NT¹.

¹ Actually, my memory could be wrong in this regard and I'm not completely sure … maybe someone more knowledgeable in those matters can confirm that the „Caps lock“ default behavior was indeed changed during the switch from Windows 9x to Windows XP?
