I'll keep this one short, My girlfriend is on her second laptop were as i'm still on my first. She has an ASUS (i'm not sure of the model) and she's always leaving it on the floor next to the bed and falling asleep with it on her knee so it's been dropped once or twice. She's only just told me about this but when ever she tries to type using the built in keyboard extra letter are added, caps lock is turned on etc.

I have used the on-screen keyboard and a USB keyboard without any issues so would i be right in thinking the built in keyboard needs replacing ?

Thanks in advanced

A concise diagnostic checklist and safe repair tips for the described Asus keyboard symptoms. Thanks to for the symptom details and to for the stuck-key thought; the following order separates software causes from hardware so a needless replacement can be avoided.

Suggested diagnostic order:

  • Reproduce the fault outside the OS (BIOS/UEFI or a live-USB Linux session). If the keyboard behaves incorrectly before Windows loads, the cause is almost certainly hardware.
  • Check OS-level causes: verify keyboard language/layout (no accidental UK/US swap), and Accessibility settings (Sticky Keys / Filter Keys / Toggle Keys). In Windows, a quick driver test is to uninstall the keyboard device in Device Manager and reboot so the driver reinstalls.
  • Physical checks next: power off, remove AC and battery, discharge by holding power for 10s. Use short bursts of compressed air to clear debris; inspect for obviously stuck or damaged keys. Avoid prying keycaps on unfamiliar laptop models. If comfortable, reseat the keyboard ribbon (power off first, document screw locations and connectors with photos). Keep screws organized — yes, the classic leftover-screw problem.

When to escalate:

  • Persistent misbehavior in BIOS after reseating/cleaning implies a failing keyboard matrix or a damaged cable/PCB and usually requires replacing the keyboard assembly or professional service.
  • If the laptop is under warranty or there is any doubt about opening it, stop and seek authorized repair to avoid voiding coverage.

Caution: avoid liquids, use proper ESD precautions, and document every step (photos and notes) before disassembly so reassembly is straightforward.

Alrightio, my guess would be the internal keyboard too. Check if any of the keys on the keyboard are stuck, that might play a big part. Other than that, I can't think of anything but the keyboard itself. Depending on the model, it shouldn't be that hard to replace, you just gotta keep track of the screws ;)
