Razer Support

Hello, my Cynosa V2 keyboard (serial number RZ03-03400200-R3U1) recently stopped working properly. I've already tried troubleshooting, but without success. The device doesn't connect properly and displays the “USB device not recognized” message. As a result, I can't update the drivers either. It isn't recognized by Synapse either.

Anyone know where to buy a replacement dongle? My headset works fine when plugged in via 3.5 cable. I’m out of warranty so don’t mind purchasing a replacement.

I have lost the QR code related to my authenticator, and I don't have a backup code either. How can I recover it?"

I got my blackwidow v4 pro about 2 weeks ago and starting last night, it doesnt want to charge, im using the original razer cord and even tried using another cord and it stays at 1% and never goes up. It will sometimes show it’s charging but it still just stays at 1%….

I lost my old phone number and forgot if I have any backup codes. But I still have my email working. I need help pls… Hope you can help.

Hello,My keyboard does not register the letter O consistently. Around 80% of the time, I have to press the key two to five times before it appears.I contacted support, but my case was closed immediately, possibly because the keyboard is no longer under warranty.The keyboard has seen very little use. I bought it around a year and a half ago, used it for only a few months, and then stopped using it. This does not appear to be normal wear and tear.I have already installed the latest firmware update, but the issue remains.I suspect the switch may be faulty. Where can I purchase a compatible replacement switch, and is it relatively easy to replace?Any help would be appreciated.Thanks.

Ever since the latest update with Synapse 3, the program “experienced an error” and needed to be restarted (which always resulted in the same non-specific error).  I tried uninstalling and reinstalling.  That got Synapse 3 to load, but the Razer mixer would have a spinning icon that would never go away and the mixer would never activate.Then I tried uninstalling and installing Synapse 4.  It loads, but then as soon as the Razer mixer has finished loading Synapse 4 will crash every time.

For over a week, I’ve had this problem when I boot my laptop. I’ve looked everywhere to fix the problem. I’ve tried everything. I even completely reset my laptop and the message appears all the time. Can you help me?

My new Razer Blade 2026 freezes for like 3 seconds every time I switch gpus (e.g. start a game). Everytime it does It makes a sound like a new device is connected, as if it detects a new screen or sth. How can I stop this? Tried DDU and new gpu drivers already, no luck. Model is RZ09-05818GN3

So other than constant connectivity issues, My volume Wheel no longer works at all, and yet it’ll still adjust my volume  by 1 or 2 when I’m not touching it at random times. Also the Media keys do not work at all if the keyboard is plugged in, so I have to use 2.4Ghz or Bluetooth but I have connectivity issues so it will either disconnect constantly, think I’m long pressing a key, or disconnect after not touching the keys for a few seconds. 

I’ve had issues with my keyboard and was sent an email by Razer support asking for a description of the problem and a video showing it but every time I try to email a response I’m told the delivery has failed. What can I do to fix it?

My first case - # 220809-000803I'm using the old Razer Kraken Pro headphones from 2016, and I'm having a problem. I can't update my Windows because after updating to version 22h2, my Razer Surround Pro stops working. Is there any way to solve this issue and get a similar sound quality to the 2016 Razer Surround Pro?

I am unable to rebind any buttons on my mouse. I am using the 1.14.0.0 firmware version. It does not work at all. I have reinstalled the software, factory reset the mouse, closed it, reopened, removed the dongl, used the dongle, etc. nothing works AT ALL. I need this fixed.

Hello, I'm Dylan. I want to help a friend who has a disability and can only use his right hand. I can't find a one-handed mouse or keyboard designed for the right hand. Could you please suggest one of your products that might fit his needs? Have a good day!

Hello, for a few days now the Razer Central Service service/process does not stop consuming my cpu, I cannot use razer synapse with any other application because the pc shoots up to 100% use

I've been many others with the same issue. I had to update to synapse 4 because I was having issues in synapse 3 thinking the update would solve my problems but now my keybinds don't work.I've tried uninstalling synapse, restarting PC, factory reset mouse, clearing profiles, making new profiles, razor cleanup tool. Everything I could possible think. If i close synapse completely my keybind buttons work. I'm assuming its using the on-board profile but they my wheel doesn't scroll, zoom, or pan.This setup has been integral to my workflow and its really slowing me down. Any fix or work around?

After installing synapse 4 I am unable to play decently, dpad on tartarus is stuck all the time, the naga trinity side panel sometimes doesnt light up/work… how can I downgrade to synapse 3?

I connected my Hyperflux v2 mousepad for the first time and it automatically detect my razer basilisk v3 pro mouse so i thought everything was working great but i can’t access the battery healts optimizer panel. It’s grey and telling me that i need to connect a compatible razer mouse and activate hyperspeed mode but it’s already done. If it wasn’t the case it wouldn’t be able to syncronize in the first place. I would like to know how to acces it. 

I'm having a problem with the optical sensor on my Razer Naga 2014.Sometimes it starts working again after I restart the PC.The buttons work correctly—everything is normal there.*photo removed by moderator

Hi, I bought a Razer Orochi V2 from an online store, but couldn't verify if it's authentic. Could anyone help verify?Please find the attached photo for the S/N and P/N. 

Hi, my Razer Blade 14 (2021, RTX 3070 model) developed a swollen battery — the trackpad area was bulging and the bottom panel was lifting. I've since removed the battery to stop further damage/risk, so the laptop is currently not running.Could someone from Razer Support help me getting a replacement battery? Happy to provide serial number, and additional info if needed.Thanks in advance.

I bought a second-hand Iskur, but unfortunately, it didn't come with the neck pillow. Since Razer chairs have a unique design, not all pillows stay in place—they tend to slide upwards. I’ve searched everywhere, but it seems impossible to find a suitable replacement, and the original black version appears to be unavailable worldwide. Does anyone have a solution?

Hello, I’m having a power supply issue with my Razer X Chroma. When I try to switch it on, there’s a spark near the power button. I imagine this is down to the power supply, and I was wondering if it’s possible to order just the power supply so I can replace it, or if there’s a way to find out which authorised retailers near me could replace it (in the city of Lyon, France)Many thanks in advance to anyone who can help.
