Well, you don't want things to go "ka-boom" :-)... By that I mean to explode.
CR batteries are not rechargeable and solar panels are charging whatever battery you have in this keyboard.
By shielding the light to solar panels (with black tape for example), the solar panels will not charge the battery inside anymore (you can check afterwards whether you have shielded the panels from the light enough with the Solar app if you hold the keyboard directly under some strong light source like a desk lamp).
But nowadays you can usually buy the ML2032 so if you have this option, I suggest to buy this one.
Yes, on the bottom right side of the “V” key there is no screw hole. But there is one between Space bar and “V” key.
When you switch off the keyboard with the on/off button you should really turn it off and therefore no battery drain should occur.
If I was you, I would check if the LEDs lights up When you press the button above to the Num-Lock button. If yes, tha maybe check if you have some dirt in the on/off switch that can cause it not working.
Or your ML2032 is some cheep fake battery :-).. Or it is in the end of its life..
I think that it can work. Just be sure that not light is delivered to the solar panels, because CR2032 can not be charged. Shorting the leads is 100% safe.
Side note: I didnt replaced my CR2032 yet since I posted this guide... :-). I am pretty satisfied
I am not sure If I understand you question. When I was chating with the manufacturer of the ML2032 they said that this battery could be dangerous so they are not shipping it to the end customers.
Hey, if you short out the leads from solar panels or stick some realy dark tape, which will prevents that no light is delivered to solar panels (you have to be sure, because CR2032 can not be charged), than you should be safe.
I am running K750 with CR2032, but I have shorted the leads to solar panels.
Hey, thats a pretty good tip - I'll use that when battery in my mum's K750 keyboard goes away.
I would just ensure that Solar App is showing zero in under a direct light of your desk lamp.
Battery still works like a charm without any notice of capacity drop (if Solar App provides correct readings)
Hey... Without turning the keyboard off, its working very well.. Solar App still showing that the capacitiy is High and status is Excelent :-)
Since I do not believe the batteries from eBay nor Amazon, so I decided to deactivate the solar panels and use a common CR2032 battery and it works just fine :-).
It requires a little soldering, and in order to get hands on the cables, so you need to carefully peel off the plastic top deck and unscrew a few screws.
In SollarApp then see the battery capacity and expected no supply of solar energy.
I have it documented on photos, so maybe I will post it here as a guide.
