Quick answer
When keys produce consistently different symbols, compare the selected input layout with the physical keyboard. A layout mismatch is different from a key that does not respond.
Understand the issue
Use a harmless text editor to test several punctuation keys. Do not test by exposing a password. Note whether letters work normally and only symbols differ, especially after changing languages or using a shortcut.
Step-by-step checks
- Read the current input-language indicator.
- Choose the layout matching the physical keyboard.
- Retest punctuation in a plain text editor.

What the results mean
If the same physical key fails in every layout, investigate the input device rather than continually changing language settings.
| Stage | Action |
|---|---|
| Start | Read the current input-language indicator. |
| Compare | Choose the layout matching the physical keyboard. |
| Next step | Retest punctuation in a plain text editor. |
Distinguish an input setting from a physical device fault
Record whether the issue affects one key or button, the entire device or only one application. Keyboard layouts, accessibility settings, shortcuts and hardware damage can produce similar-looking symptoms. A changed symbol or unexpected action does not automatically mean the keyboard or mouse needs replacement.
Use a simple local text field or another harmless task to compare behaviour. Where practical, test a known-good external device and inspect the relevant input settings. For a wireless device, check its normal power, pairing and connection status before changing drivers. Keep accessibility features that the user relies on in mind; disabling them without checking can create a different usability problem.
Make one reversible adjustment and repeat the original action. Check typing, shortcuts and the affected application afterwards, including sleep or reconnection if those trigger the problem. Do not remove keycaps, spray liquid or open the device without knowing its service requirements. If input failure follows a spill or physical impact, prioritise the appropriate hardware assessment rather than repeatedly powering the machine on to test it.
Before you finish
- One app compared with another
- Input layout and accessibility settings reviewed
- Known-good device compared where practical
- Original action retested after a single change
Repair checklist
If you need help, send RJ Computers your device model and the results of the checks above. Explain what must be preserved before work starts, especially files that have no other copy.
- Confirm assessment charges and what the quote includes.
- Ask for approval before additional parts or destructive software changes.
- Test the original symptom at handover and keep the repair details.

Frequently asked questions
Does the Windows display language determine every key's symbol?
The input layout controls typing, and it can be configured separately from the display language.
What should I record before requesting help?
Record the full model, exact error or symptom, recent changes and what you already tried. Explain whether important files have a separate backup.
How do I arrange a repair assessment?
Call RJ Computers on +91 99715 24677 or use the WhatsApp booking button. Confirm availability, diagnostic fees and the scope of work before booking.
Conclusion
If the same physical key fails in every layout, investigate the input device rather than continually changing language settings.
