Make sure it is compatible. Match the voltage and amperage on the keyboard with the power cord's specs. If you don't, you may damage the keyboard.

It's doubtful it's a problem that a reset would help. It sounds more like a problem with the contact on that specific key. I suggest taking it to the repair shop.

Suggest you power with batteries and try the keyboard. If no problem it is likely the power adapter has a problem, or loose connection. I've included the manual to help you discover the problem and resolve, Hope this helps? http://support.casio.com/storage/en/manual/pdf/EN/008/CTK451_EN.pdf

EBay has the Song Book for the LK 43/44 (which may be the same) so it's worth checking there from time to time. http://www.ebay.co.uk/itm/CASIO-Song-Book-LK43-44-score-2-/361904464219?hash=item54432fe15b:g:R3oAAOSwfVpYowZU

Yes. But it depends which connectors you have on your laptop. If you have a small (3.5mm) stereo jack input, then you need one cable with a small stereo 3.5mm jack on one side and a big stereo 6,3mm jack on the other side. (Take a look at the picture below). Then you plug in side with a small stereo jack in your laptop "line in" input and other side of the cable with a big stereo jack to your Casio CTK-1100 Phones/Output plug on a keyboards rear side... Be sure to adjust the volume on both the Casio (output volume) and laptop (input volume)... Cheers!

Sounds like a lack of power from the external "wall wart" power supply. Is it the correct one that can supply enough current for a chord to be played? (a chord will play more notes at the same time & pull more power from the supply in order to make the sound(s)) If it's the correct power supply or one of the correct current rating check the cable & the connector both at the end of the cable & where it plugs into the keyboard. Perhaps the lead has been tugged accidentally? / Damaged in some way? Turn the volume down a little & see if that helps - that will confirm the power theory :-) Good Luck!

I would say yes. Especially if putting in the headphones cuts out any external speakers.

Yes that is sure likely to be the reason as when the headphones are plugged in the audio is disabled to the device speaker

Check Ebay for a used keyboard or parts.

Go to the Casio factory product support site to see if the manual is available.

No, the switching is done by the headphone jack. However if you replace the headphone jack itself ou can install one that makes them both on at the same time but then you couldn't switch the speakers off. Or you can wire a switch into the circuit to do it.

This device operates internally at 12VDC. It can run on D-Cell batteries. It uses a transformer-based power pack to convert A/C to DC for the unit. What possible benefit do you see in converting this (if you even could) to a 3-wire grounded system? There most likely is already a fuse incorporated into the PCB internal to the power pack. You cannot wire A/C directly to the device as it is not internally capable of using the voltage. Any ground that you placed on the device would only be effective to the power pack and would not continue on to the device itself. It seems like a waster of time and effort.
