ASUS laptop keyboard test – press the keys to check every key

ASUS laptop keyboard problems – how to use this test

This page is designed for owners of ASUS laptops – including ASUS VivoBook, ZenBook,
ROG, TUF Gaming, ExpertBook and ProArt models – who want to check whether their
built-in keyboard is still working correctly. Press every key on your ASUS keyboard
and watch if the corresponding key on the layout above lights up.

1. Some keys on your ASUS laptop keyboard are not responding

If only one or two keys on your ASUS keyboard do not light up in this test, the most common
causes are:

• A worn-out switch under the key after years of daily typing or gaming.
• Dust or crumbs stuck under the keycap, especially on older VivoBook and gaming models.
• A key that has been hit too hard or damaged when cleaning.

Try gently cleaning around the key and repeat the test. If the key still does not register,
the internal ASUS keyboard assembly is likely defective and should be replaced.

2. A whole row or block of keys does not work on your ASUS keyboard

When an entire row (for example Q–P) or a block of keys fails the test, this often indicates:

• A partially disconnected keyboard ribbon cable inside the laptop.
• Damage to the keyboard matrix on the ASUS keyboard PCB.

Software fixes usually cannot repair this type of damage. In many ASUS laptops, the keyboard
is a single field-replaceable unit that can be swapped without replacing the whole machine.

3. Wrong characters or “ghost typing” on ASUS laptops

If you press one key and another character appears on the screen, or your ASUS laptop starts
typing by itself, the internal circuits of the keyboard may be damaged. This is very common
after a liquid spill or heavy impact and usually means the keyboard needs to be replaced.

4. Keys that repeat by themselves

A key that prints the same character several times, even though you only press it once,
is a typical symptom of a worn ASUS keyboard switch. You can try adjusting the key repeat
settings in Windows, but if the issue shows up in this online test as well, it is almost
certainly a hardware problem.

5. Backlit ASUS keyboard issues

Many newer ASUS laptops (for example ROG and TUF Gaming laptops, or ZenBook ultrabooks)
come with backlit keyboards or RGB keyboards. This tool only tests whether the keys register
correctly – it does not test the backlight or RGB effects. If the keys work but the backlight
does not turn on, the LED backlight circuit or the backlight cable may be faulty. In that case,
replacing the keyboard with a new backlit ASUS keyboard is usually the cleanest fix.

6. After liquid damage on ASUS keyboards

Coffee, tea or water spills are a very common reason for ASUS laptop keyboard failure.
The keyboard may work for a few days or weeks and then more and more keys start to fail.
If your ASUS keyboard shows several dead or unstable keys in this test after a spill,
it is strongly recommended to replace the entire keyboard to avoid further problems.
