Razer laptop keyboard test – check every key on your Blade

Razer laptop keyboard problems – quick check for Blade and gaming models

This page is for owners of Razer laptops – especially Razer Blade 14, 15, 16, 17,
Blade Stealth, Razer Book and other Razer gaming notebooks – who want to verify that
every key on the built-in keyboard is still working correctly.

How to use this Razer keyboard tester

• Make sure this page is active (click once inside the page).
• Press each key on your Razer keyboard one by one – including WASD, number row, function keys and arrows.
• When a key is working, the matching key on the on-screen keyboard will light up.
• Use the counter to see how many keys you have already tested.

1. Dead or unresponsive keys on Razer Blade laptops

Gaming-heavy keys like WASD, Space, Shift and
Ctrl are used the most and are the first to fail on many Razer laptops.
If any of these keys do not light up here, even after cleaning around them, the internal switch
is likely worn or damaged and the keyboard module usually needs to be replaced.

2. Full row or block not working (for example number row or arrows)

If a whole block of keys fails this test – such as:

• The top number row (1–0),
• The arrow keys cluster,
• Or the F1–F12 function keys,

the most common causes on Razer laptops are:

• A partially loose keyboard ribbon cable inside the slim Blade chassis.
• Damage to the keyboard matrix PCB, sometimes caused by flexing or local heat.

Driver updates or Windows settings rarely fix this. In most cases the internal keyboard
assembly has to be replaced.

3. Wrong characters or “ghost typing” on Razer keyboards

If you press one key and a different character appears, or your Razer laptop starts
“ghost typing” without touching the keyboard, there is usually internal circuit damage.
This often happens after a drink spill or when the laptop has been heavily used for gaming.
Software resets will not fix this reliably – a new keyboard is the safest solution.

4. Double-press or sticky gaming keys

A very common issue on gaming machines is double-pressing: for example you press
D once and get “DD”. On Razer laptops this usually means:

• The mechanical dome or scissor mechanism under the key is worn.
• Dust or small particles are affecting the travel of the key.

You can try gently cleaning and adjusting key repeat settings in Windows. If the problem
still appears in this online test, it confirms a hardware problem in the keyboard itself.

5. Chroma RGB backlight issues vs. key detection

Razer laptops often use per-key Chroma RGB lighting. This tester only checks whether
a key press is detected – it does not test RGB lighting. If your keys
light up in this test but not in Razer Synapse, then:

• The RGB backlight or a specific color zone may be damaged.
• Synapse or the Chroma driver may need to be reinstalled.

If a key does not respond here and also has backlight problems, the entire
keyboard module is usually defective and should be replaced.

6. After liquid damage on Razer Blade keyboards

Coffee, energy drinks and water are a common reason for Razer keyboard failure. Typical
symptoms after a spill include:

• Keys that stick or feel heavy.
• Random characters appearing while gaming or typing.
• Rows or groups of keys that no longer respond.

If your Razer keyboard behaves like this and several keys fail in this test, replacing
the complete keyboard assembly is strongly recommended to avoid further issues later.
