Hi @Kazza-,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
The high-pitched 2-tone hum you’re hearing from your HP ENVY 6132e when it’s in sleep mode is a known issue that has been reported by users of multiple HP printers. This issue, while not necessarily harmful, can definitely be quite annoying.
Here are a few potential causes and solutions you can try to stop or mitigate the sound:
1. Disable Sleep Mode
- If the noise is only occurring when the printer enters sleep mode, you could try disabling sleep mode or changing the sleep settings on the printer. This way, the printer will stay on or in a low-power state without fully entering sleep mode.
- To do this, check the printer's settings (either on the printer's control panel or through the HP Smart app or web interface).
- Navigate to settings> Power Settings or Sleep Mode.
- Disable sleep mode or increase the time before the printer goes into sleep mode.
2. Update Printer Firmware
- A firmware update might address this issue, as it could be related to a software bug.
- Check for updates for your printer using the HP Smart app or visit the HP Support website to find the latest firmware updates for your HP ENVY 6132e.
3. Reset the Printer
- Performing a reset might clear any settings or glitches causing the noise.
- Turn off the printer and unplug it from the power source for about 1 minute.
- Plug it back in, power it on, and see if the issue persists.
4. Check for Electrical Interference
- Sometimes, electrical interference or grounding issues can cause unusual noises in devices. Try plugging the printer into a different power outlet or using a different power strip to see if the issue resolves.
5. Reduce Printer Sound Volume
- While the two-tone hum is a hardware issue, reducing the volume of sounds (if your printer has that option) might make the hum less noticeable.
- Check your printer’s settings menu to see if you can adjust the volume of notifications or sounds
I hope this helps.
