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.

  1. FN + Spacebar Charge indicator only displays after connected.
  2. Since reconnecting the keyboard seems to have stabilized but the battery has problems
  3. It jumps from full charge to almost empty charge within 1 hr
  4. In other words I charge it so it's green on #'s up to 9 or 0
  5. Then it drops to a 3 or 4 within 30 mins. Never see it show battery level at 5,6,7,8
  6. Either the battery is dying or the firmware is not displaying with 1 battery correctly.
  7. Becuase of this I purchased 2 batteries off of ali express for 40$
  8. See local batteries link. New batteries seem good so far.
