Hi Grandpa Norizan! 😊
The good news is that I would NOT reinstall Windows 10 yet.
Because both the touchscreen and the wireless keyboard/mouse stopped working around the same time, this often points to:
- A Windows driver problem.
- A USB controller problem.
- A Windows update issue.
- A hardware setting that was accidentally disabled.
- A motherboard or internal hardware fault.
Let's try the easier software checks first.
Step 1: Test whether the laptop still recognizes touch devices
Press:
Windows Key + X
Then select:
Device Manager
Look for:
- Human Interface Devices
- Universal Serial Bus Controllers
Under Human Interface Devices, see if you can find:
- HID-compliant touch screen
If you see a small down-arrow on it:
- Right-click
- Enable Device
If you see a yellow warning triangle:
- Right-click
- Update Driver
Step 2: Check if USB ports are working
You mentioned your wireless keyboard and mouse are not working.
Remove the wireless USB receiver and plug it into another USB port.
Then try:
- A USB flash drive
- A USB external hard drive
Question to yourself:
- Does the flash drive appear in Windows Explorer?
If none of the USB ports work, that gives us a very important clue.
Step 3: Restart the USB Controllers
In Device Manager:
Expand:
Universal Serial Bus Controllers
For each item called:
- USB Root Hub
- Generic USB Hub
- USB Host Controller
Right-click and choose:
Uninstall Device
Do not worry.
After uninstalling them:
Restart Windows
Windows will automatically reinstall the USB drivers.
Many strange USB problems are fixed this way.
Step 4: Check whether Touchscreen was disabled
In Device Manager:
Expand:
Human Interface Devices
Find:
HID-compliant touch screen
Right-click it.
If you see:
Enable Device
click it.
If you see:
Disable Device
then it is already enabled.
Step 5: Run Windows System File Checker
Open Command Prompt as Administrator.
Type:
Press Enter.
Wait until it reaches 100%.
If Windows finds corrupted system files, it may repair them automatically.
After that, run:
This can repair deeper Windows issues.
Step 6: Check whether Windows recently updated
Press:
Windows Key + I
Go to:
Update & Security → View Update History
Ask yourself:
"Did the touchscreen stop working immediately after a Windows update?"
If yes, the update may have affected the driver.
Step 7: Acer Aspire R15 Specific Check
Because your Acer Aspire R15 is a foldable touchscreen model, Windows uses special sensors to switch between:
- Laptop Mode
- Tent Mode
- Tablet Mode
Sometimes these sensor drivers become confused.
Try:
- Shut down completely.
- Disconnect charger.
- Hold the power button for 20 seconds.
- Start the laptop again.
This sometimes resets the embedded controller.
Step 8: Check the BIOS
Restart the laptop.
Press F2 repeatedly while booting.
Enter BIOS Setup.
Look for:
- Touchscreen
- Internal Pointing Device
- USB Configuration
Make sure nothing is disabled.
Do not change unrelated settings.
My suspicion
Since:
✅ Touchscreen stopped working
AND
✅ Wireless keyboard stopped working
AND
✅ Wireless mouse stopped working
I suspect either:
- USB controller driver corruption (most likely)
- Human Interface Device driver corruption
- Windows update issue
These are software problems and usually do not require reinstalling Windows.
Last resort before reinstalling Windows
Try:
Settings → Update & Security → Recovery → Reset this PC
Choose:
Keep my files
This repairs Windows while preserving personal files.
I would try this only after all the steps above fail.
Grandpa Norizan, one important clue:
Does the laptop's built-in keyboard and built-in touchpad still work normally, or are they also having problems?
That answer can help narrow down whether this is a driver issue or a hardware issue. 😊
WHOOOOAAAAA !!! 🎉🎉🎉
Attaboy, Grandpa Norizan! 😄
That is wonderful news indeed! I'm very happy to hear that Step 3 (reinstalling the USB controllers) and Step 4 (re-enabling the HID touchscreen device) brought your Acer Aspire R15 back to life.
What most likely happened was:
- Windows temporarily got confused about one or more USB/HID devices.
- The touchscreen driver may have become disabled.
- The USB controller driver may have become corrupted or failed to initialize properly.
By uninstalling the USB controllers and restarting, Windows was forced to rebuild those drivers from scratch. Then enabling the touchscreen allowed Windows to communicate with the touch panel again.
This is actually a much better outcome than reinstalling Windows 10 because:
✅ You keep all your files
✅ You keep all your installed programs
✅ You save many hours of work
✅ No need to reconfigure your laptop
Grandpa Norizan, I would also suggest creating a System Restore Point now that everything is working properly.
You can do this by:
- Press Windows Key
- Type Create a restore point
- Press Enter
- Select drive C:
- Click Configure and make sure protection is ON
- Click Create
- Give it a name such as:
Acer R15 Working Properly
If Windows ever misbehaves again, you may be able to roll back to this good configuration.
And I must say, your trusty 15.6-inch foldable Acer Aspire R15 seems to have plenty of fighting spirit left in it! 😊
Thank you for coming back and sharing the good news. It always makes my day when a problem is solved without having to reinstall an operating system.
Take care, Grandpa Norizan, and happy computing! 💻👍😄
