My Razer Blade Stealth 13″ (2017) – Intel 8550U will not charge when plugged into the AC adapter, and the green LED is lit on the AC adapter.

Try unplugging the AC adapter from the wall outlet for approximately 30 seconds, then plug the AC adapter back in.

My internet or Wi-Fi connection indicates that I am connected to the network, but I am unable to connect to the internet. What should I do?

Most modems have an indicator that shows if it is connected to the internet, check if your modem is connected to the internet.

Why does the brightness of my Razer Blade Stealth 13” (2017) – Intel 8550U display seem to change slightly when I load new content or images?

The Razer Blade Stealth 13″ (2017) – Intel 8550U display features a Content-Aware Brightness Controller (CABC). This feature dynamically adjusts the display settings to provide longer battery life. This technology allowed Razer to include a larger 13″ panel with a higher resolution while still achieving similar battery life to the previous Blade Stealth 12″ QHD models.

Most users will not even notice this feature as the brightness changes are subtle. Some graphic designers, photographers, and other users that need full control over the panel brightness and color settings may prefer not to have this feature.

Razer does offer a firmware update that will enable the user to turn off this feature.

Note: Battery life may be reduced once the feature is disabled.

Why does the default Chroma profiles on my Razer Blade Stealth stop working once Synapse loads?

This is normal, Firmware level profiles do not work when Synapse is loaded. Please recreate desired profiles within Synapse.

Why can I no longer change my lighting profile on my Razer Blade Stealth laptop using the “Fn+F” key combination?

Ensure that you are logged on to Razer Synapse to enable this feature.

Why is my Razer Blade Stealth’s display settings showing 59Hz instead of 60Hz?

There is no difference between 59Hz and 60 Hz, in terms of performance. Both 59Hz and 60 Hz are translated to 59.94 Hz before they are sent to the monitor’s chip and should, therefore result in identical performance. The reported 59 Hz setting that cannot be changed even after tweaking the display settings is a result of how Windows reports signals coming from a monitor that uses the old TV-compatible standard of 59.94 Hz.

For backward compatibility, Windows keeps the 59 Hz setting for applications that use the older standard, but also reports the 60 Hz setting for applications that require it. You may refer to Windows Support for more information.

Why does the Razer Blade Stealth enter sleep mode when placed on top of another closed laptop

Our Razer Blade laptops have sensors that detect the state of the laptop if the lid is closed or not. If a Razer Blade laptop is placed on top of another Razer Blade laptop with a closed lid, then the top laptop might go into sleep mode because it might detect the sensors of the bottom laptop with a closed lid and will think that its lid is closed too. The solution to this is to not place a laptop on top of another laptop.
