Blackwidow V4 Low-Profile Hyperspeed - Wireless Connectivity Issues (BT-Dongle)

I have a blackwidow v4 hyperspeed wireless. Today it started to enter in sleepd mode between typing, for example if I stop for more than 2 secs it enters in sleep mode.  I try to reste the bluetooth connection, but  it didn’t work. tried to reset to reset to default settings form synapse, it didn’t work. Try hard reseting (esc+caps+ space bar) it didn’t work. uninstall/install synpase and the latest firmware, it didn’t work. No matter what I do, the only way the keyboard works is wired (it recognices bluetooth profiles but only while wired). I need an honest suggestion, whta should I do? is there an update that I have to try or will you reimburse muy money or should I ask for a refund?

Hi Felipesanme,

 

Try connecting the Razer BlackWidow V4 HyperSpeed to snother computer with no Synapse on it. If it’s behaving the same, then since a basic reset and reinstall didn't work, Windows might be aggressively putting your USB hub to sleep. Try the following: 

 

  1. Press Windows Key + X and select Device Manager.
  2. Expand the Universal Serial Bus controllers section.
  3. Right-click the USB Root Hub or Generic USB Hub and select Properties.
  4. Go to the Power Management tab and uncheck "Allow the computer to turn off this device to save power".
  5. Click OK (repeat this for all USB Hubs listed).

 

If none of the above steps resolve the issue, PM me your Razer BlackWidow V4 HyperSpeed’s
