The shift key on my laptop keyboard has stopped working. I removed it to try to fix and now can't get it back on.

If this is a wireless keyboard, you can do two things to try to correct this issue. You can remove the batteries and leave it sit for a few minutes and try again, or you can replace the batteries and see it that helps.

Is this the only problem with the keyboard not getting uppercase to work ?
While Acer laptops are built to be used on the go, they are not indestructible. An accidental drop or even normal wear and tear over an extended period of time can cause the laptop keys to become dislodged and fall out. Debris can also build up inside the keys and make them stick or stop working. Fixing the keys on your Acer laptop is a quick process that does not require taking the unit to a professional repair shop.

Power off the Acer laptop and flip the unit over. Slide the battery release lever over and lift the battery out of the laptop. Turn the laptop back over and open the lid. Look inside the open area on the keyboard where the key would normally go. Check to see if the plastic retaining clip is still inside the hole. Locate the plastic retaining clip if it fell off the keyboard along with the key. Use a pair of tweezers to set the clip back inside the hole. Line up the holes on the clip with the four raised nodules inside the keyboard hole. Set the key back onto the plastic clip. Push the key down until it clicks into place. Flip the laptop back over if there are keys that are not working properly. Use the Phillips-head screwdriver to remove the three screws on the left side of the case that hold the keyboard in place. Turn the laptop back over so that you can see the LCD screen. Push the thin end of a flat-head screwdriver under the LED indicator strip above the keyboard. Pop the strip upward and pull it off the laptop. Lift the keyboard up towards you until the long ribbon cable running from the bottom of the keyboard to the motherboard comes into view. Unplug the cable from the port on the motherboard and then pull the keyboard and its ribbon cable off the case. Spray out the underside of the keys and the inside of the Acer laptop case with canned air. Reassemble the keyboard, LED indicator strip and battery.

When a keyboard stops working, has odd key letters, stuck keys and non-functioning keys for no reason at all, the laptop may have an easy fix solution. However, if liquid spilled on the laptop or the laptop was dropped and as, a consequence, the keyboard doesn't work, or the keyboard device has simply failed, fixing the problem may require a more involved laptop keyboard replacement.

I would suggest you re-install the keyboard driver as a first move.
Navigate to the keyboard on Device Manager and make sure no problems are highlighted.
If all is OK go to the manufactures support website and download the new software.

You have 2 Shift keys on the keyboard. If the other shift key is working then the shift key that is not working is defective. You should consider replacing the keyboard on your laptop. There is no setting on Windows that can disable the shift key.

**Note : If both Shift keys are not working, Try to check if sticky keys feature on windows is on. Sticky keys should be disabled. To disable sticky keys, Click on start and Go into control panel > Accessibility Options, and under keyboard there is sticky keys. Remove the tick and click apply and OK.



**If "Use Sticky Keys" is unchecked, that means sticky keys is disabled.

You may remove the key and remove any dust in there and place it back. This should fix the problem

Or else i think you have to change the keyboard. But in some cases, the keyboard is embedded to the motherboard. So that might be expensive, so in that case, try to use an external keyboard.

If some keys on your keyboard aren't responding, the sensor under the key may be going bad. Fortunately replacing the entire keyboard for your Dell D600 is not very expensive. I recommend the keyboard at this web store:

To install a replacement keyboard, the plastic panel above the keyboard would need to be removed, which may be held on by some screws from the underside of the laptop. Then you can access the keyboard screws, and gently remove the keyboard cable from the motherboard.

Hi,

Looks like the French keyboard mapping is still in effect.
You can try changing the keyboard keys back to where they were by pressing:

Left CTRl + left Shift at the same time. then try typing the ?/ key. You may have to try this a couple of times to get it to work.

If it does work, try the right ctrl/left shift key.

Also found this:

Control Panel, Regional and Language Options, Keyboards and Languages,
Change Keyboards. Select the keyboard you that's causing you grief and
choose Remove.

If you don't remove the keyboard map, when this switch happens, you'll have
to exit the application you're in (Outlook, for example), change keyboards,
and restart the app. Changing keyboards without restarting the app doesn't
seem to change the mapping.

Hope this helps!
