Wobkey Rainy 75 Troubleshooting

Stops working

OK so this is the 2nd time it happened. FN +Space bar does not show Battery. Nothing works. No Lights. If I plug it in I get lights. I fixed this somehow before and I can't remember what I did. OK got it back by Holding FN+Backspace for 10 seconds. It took 10 seconds to activate back light and wake it up? WTF is this thing doing?

So I really tried to use keyboard over bluetooth 1 this morning and costant problems. Would just spam keys then die every 10 mins. In other words I can type fine for 5-10 mins then all of sudden spam the letter p for 40 times then die. No response on any key press. Refused to go into dongle F4 Mode. Just realized I was not clicking function + Tab to switch connection Modes. Was clicking FN+F4 which does nothing. Could only get BT 1-3 to light up again after holding FN+Backspace for 10 seconds. So I decided to reflash firmware. I was on latest version. I did not do a factory reset. If this does not fix I will try that later. I did go into VIA and fix my delete key, etc over wired connection then switched to wireless, after I got everything the wany I want. I figure i'll try dongle F4 first since even scroll on my BT Mouse was acting wonky.

I got the rainy 75 from drop.com. I really like it but I keep having strange issues where it just dies in the middle of typing. I only use it wirelessly. I reflashed the firmware and that seemed to fix it for a couple days. I have Standard Version so comes with RGB and one battery. Can I purchase a replacement battery? Can I use two battery's in this model? I have a feeling something is off with this battery as the battery level indicator seems random. Like I'll try it and it will show full then 2 seconds later it shows 3, then 6, etc. I already swapped a bunch of switches and used via to customize so I really just want to fix it.

Screen Shot

2025-2-2 Battery check


Torx T7 50mm screw driver





  1. Torx T7 50mm screw driver
  2. Nothing seems loose
  3. Battery -QS4541113 3500 mAH + 24E10 3.7V 12.95Wh
  4. QS: Likely the manufacturer's or series code.
  5. 4541113
  6. 45 mm == 4.5 mm thickness.
  7. 41 mm == 1.61417 Inches (Height)
  8. 113 mm == 4.44882 Inches (Must be width Length)
  9. NTC battery
  10. NTC stands for negative temperature coefficient, and it refers to a thermistor that monitors the temperature of a battery. NTC thermistors are often used in lithium-ion (Li-Ion) batteries to help prevent overheating and other safety issues.
  11. Three wires NOT 2.
  12. 24E10 is most likely date of manufacture

Thoughts

  1. For wireless this keyboard is annoying
  2. Charge indicator never displays while plugged in. Why?
  3. I am supposed to press FN + Space bar to check if it is actually charging while plugged in, but It won't show anything since it wakes up from sleep and tries to connect to dongle or BT
  4. F4 just blinks. So is it charging? Not charging? Who knows...
  5. There is no way to ever see what is going on with the battery on this thing
  6. Eventually you might get some kind of insight into that battery and the Battery level is not reliable, jumps all over the place.
  7. I am string to think this thing only charges when wireless is off.
