An HP Chromebook microphone not working during a Meet or Zoom call is usually a settings problem, not a dead part. HP’s own support forum still gets a steady stream of reports of the internal mic going silent or never showing up in apps, though, so it is worth knowing what is actually HP-specific here versus generic ChromeOS troubleshooting. I will point out where the two split.
Quick answer: Power-cycle the Chromebook, then try the HP hard reset (hold Refresh, then hold Power too, for about 10 seconds). If the built-in Diagnostics app still shows no microphone input after that, the fault is most likely hardware, and on most HP Chromebooks that means a warranty check rather than a DIY fix.
HP models where this shows up
Microphone complaints on HP’s community forum are not tied to one generation. Here is a spread of current and recent HP Chromebooks, since which reset combo applies depends mostly on whether the unit has a keyboard.
| Model | Updates until (AUE) | What matters for this problem | Reset / recovery |
|---|---|---|---|
| Chromebook 14a | June 2033 | Budget consumer clamshell, single combo headphone/mic jack | Power-cycle (hold Power about 30s), then Refresh + Power hard reset |
| Chromebook x360 14c-ca0 | June 2030 | Convertible with touch screen, often propped tablet-style for calls | Refresh + Power hard reset |
| Chromebook x2 11c (detachable) | June 2031 | Keyboard is a separate attachable piece, so recovery differs from a clamshell | Volume Up + Volume Down + Power held 10+ seconds |
| Elite c1030 Chromebook | June 2030 | Enterprise unit with an optional LTE modem, common on remote-meeting fleets | Refresh + Power hard reset |
| Chromebook Plus x360 14ct | June 2035 | Newer Plus line, longest update runway of this group | Refresh + Power hard reset |
What HP owners report about this specific issue
There is no HP service bulletin naming a specific microphone defect. What exists is a pattern of forum reports: owners on HP’s community forum report the internal microphone going silent, or never being recognized by any app, across several Chromebook generations rather than one specific model. That pattern fits a driver or connector fault more than a design flaw tied to a single SKU.
One HP-specific wrinkle worth ruling out first: several HP Chromebooks share a single combo jack for headphones and microphone. If a wired headset was plugged in and then removed, ChromeOS sometimes keeps routing input to the now-empty jack until you unplug and replug it, which looks exactly like a dead internal mic but is not one.
HP-specific fixes to try
- Unplug any headset, USB-C dock, or other peripheral, then hold
Powerfor about 30 seconds to fully power-cycle the unit. - Still nothing? Run the HP hard reset: hold
Refresh, then press and holdPowertoo, keep both held for about 10 seconds, then release. Google notes this can clear a few files from your Downloads folder, so it is not entirely harmless, just far short of a full wipe. - Recheck the microphone in the Diagnostics app, separate from whatever call app first flagged the problem.
- ⚠ This erases local data. If Diagnostics still reports no input, boot into recovery mode: turn the unit off, press and hold
Esc+Refresh, then pressPoweronce, and release Esc and Refresh once the recovery screen appears. - Still silent after all that? Check your HP warranty status with the serial number before paying for a repair. A mic that fails Diagnostics after a full reset is a hardware fault, not something a settings change will fix.
The general steps (checking permissions, confirming the right input is selected, restarting) are in our Chromebook microphone not working guide. I will not repeat those here.
If mic problems show up alongside no sound or camera issues
A microphone fault on a Chromebook used for calls often travels with other symptoms. If you are also getting no sound from the speakers, check whether one update or one app explains both before assuming two separate hardware failures. And if the camera drops out at the same time, especially mid-call, see our HP Chromebook camera not working guide, since a few notebooks in this lineup have a physical camera switch that owners mistake for a bigger fault.
Warranty and repair at HP
Most consumer HP Chromebooks carry a one-year standard warranty covering hardware failures from manufacturing defects, parts and labor included, and a dead internal mic falls into exactly that category. It does not cover accidental damage or ordinary wear, and using an unauthorized repair shop can void it.
Check your status by entering the serial number on HP’s warranty page, or open the warranty section inside HP Support Assistant if it is installed. The serial number itself is usually on the bottom of the unit, inside the battery compartment, on the original box, or on the kickstand if you have a convertible; HP Support Assistant or the System Information tool can also read it without you flipping the machine over.
If this is a school-issued Chromebook, go through your school’s IT department first. District fleets are usually covered under a separate service agreement, and IT can often swap the unit faster than an individual warranty claim would move.
Out of warranty, an internal microphone is not something most owners open the case to replace themselves. iFixit maintains HP Chromebook device pages and stocks parts through its HP repair partnership, and HP also runs its own Parts Store selling HP-branded components directly, but check a model-specific guide before assuming the part is sold separately for yours.
FAQ
Does a Powerwash fix an HP Chromebook mic that stopped working?
Sometimes, if the cause is a stuck driver state or a bad update. It will not fix a mic that also fails the Diagnostics app hardware test, since that points to a connector or component problem rather than software.
Is the internal microphone on an HP Chromebook something I can replace myself?
Not on most models. It typically shares a board with other components rather than sitting on its own swappable part, so check warranty status first and only look at iFixit’s guides and the HP Parts Store once you have confirmed you are out of warranty.
My HP Chromebook is school-issued. Who do I contact about the microphone?
Your school’s IT department, not HP directly. Education-line HP Chromebooks are usually covered under a district service agreement, and IT can swap or repair the unit faster than an individual warranty claim would.
