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

Acer laptop keyboard problems – how to use this test

This page is designed for owners of Acer laptops – including Acer Aspire, Nitro, Predator,
Swift, Spin, TravelMate and Extensa models – who want to check whether their built-in keyboard
is still working correctly. Press every key on your Acer keyboard and watch if the
corresponding key on the layout above lights up.

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

If only one or two keys on your Acer 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.
• Dust or crumbs stuck under the keycap, especially on older Aspire and TravelMate 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 Acer keyboard assembly is likely defective and should be replaced.

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

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

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

If you press one key and another character appears on the screen, or your Acer 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 Acer 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 Acer keyboard issues

Many newer Acer laptops (for example Nitro and Predator gaming laptops, or Swift / Spin ultrabooks)
come with backlit keyboards. This tool only tests whether the keys register correctly – it does
not test the backlight. 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 Acer keyboard is usually the cleanest fix.

6. After liquid damage on Acer keyboards

Coffee, tea or water spills are a very common reason for Acer laptop keyboard failure.
The keyboard may work for a few days or weeks and then more and more keys start to fail.
If your Acer 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.

If this Acer keyboard test shows that your keys are faulty, you can
