Logitech K750 solar keeps disconnectingg and reconnecting

[Derico]

I have this annoying problem with my few months old keyboard where it keeps disconnecting and reconnecting.

I noticed the problems first when i was ingame and many times the keyboard didnt respond. Now im in windows and every now and then i get this annoying hardware removed and then hardware connected sound. Looked it up under devices and it seems to be the device "BCM20702A0". which vanishes and reappears in the overview.

The weird thing is, everytime the "BCM20702A0".disappears, another item - "Asus OSD" disappears in the list "Devices and printers"

Does this mean that the "unified receiver" is broken?

are you on windows 7?

If yes then here's the answer by Logitech team
Possible cause of problem:
1.Conflict of Windows installed drivers
2.Scheduled task running in background (i.e. indexing, event logging, etc.)
3. Internet when accessing secured servers (security notifications pop-ups)

Application running when problem accurse:
1. Internet Explorer
2. MS Office Applications (Word, Excel and Outlook)
3. Garmin GPS software (no device(s) attached at the time when problem occurs)

Suggestions recommended by Logitech support team:
Replace BT batteries, scanned system for virus and common system/hardware problems, modified system settings, update BT drivers, update bio’s, update Windows, re-install Windows, re-install drivers downloaded from Dell website, updated bios again, replaced keyboard & mouse, replaced BT adapter, replaced hard drive with special configuration from Dell, and replaced my Motherboard.

Thanks for your answer. I believe i found the problem. The Energy tool of K750 Solar seems to be very inaccurate at displaying the keyboard's battery status.

It appears that once the battery status is at ~70 percent, it's going to have very frequent blackouts. Even this morning, when it reported a batter status of 79% it was disconnecting and reconnecting all the time. Now that i've had it recharge in the sun this entire day it appears to be working fine again.
