When Bluetooth on an Acer laptop fails, Microsoft's guide is the reference: run the Bluetooth troubleshooter in Get Help, make sure Bluetooth is turned on in Settings and airplane mode is off, remove and re-pair the device, and update the Bluetooth driver (an outdated or incompatible driver is one of the most common causes, and you can update it in Device Manager under Bluetooth).
Microsoft also has separate articles for a device that keeps disconnecting, for Bluetooth that has vanished from Windows and for a device that connects with no sound. On most Acer laptops the Bluetooth radio sits on the same wireless card as Wi-Fi, so a fault in both points at the card and a fault in one points at pairing or the driver. Move the laptop away from a busy USB 3 dock or drive, which can disturb the 2.4 GHz band.

Before you touch a setting
Record this first — changing settings destroys the evidence

- Which Bluetooth device fails and whether it works on another computer or phone
- What Settings, Bluetooth and Device Manager show
- Whether a dock, hub or router sits close to the laptop

0 of 7 completedRun the Bluetooth troubleshooter
ReversibleOpen Get Help and run the Bluetooth troubleshooter, as Microsoft's guide says, and follow each suggestion it makes before moving on.
Turn Bluetooth on
ReversibleOpen Settings, Bluetooth and devices; check that airplane mode is off and that no wireless function key has switched the radios off.
Remove and re-pair
ReversibleRemove the device in Settings and pair it again from scratch, putting it into pairing mode first so it is discoverable.
Update the driver
ReversibleUpdate the driver, by opening Device Manager, Bluetooth, choosing the adapter, Update driver, or using Acer's support page.
Update the BIOS
ReversibleUpdate the BIOS, by installing the latest BIOS for your full model number, with the charger connected.
Reduce interference
ReversibleUnplug USB 3 devices and docks near the antenna and retest, because these can interfere with the wireless signal.
Check Wi-Fi too
ReversibleCheck Wi-Fi too, since a fault in both points at the shared wireless card in the laptop.
Model-specific
What is true of this model and not of its siblings
- Radio sharing
- On these Acer laptops Bluetooth normally shares the wireless module with Wi-Fi. A fault in both points at the module.
- Repair cost
- A Bluetooth fault is nearly always pairing, a driver or a setting, which costs nothing. If the wireless card is at fault, an independent shop repair is typically $99 to $299 with a free diagnostic, per BadgerLayer's 2026 laptop repair guide.
- Other models this page answers
- These steps also fit the Aspire 5 A515 family.
Stop boundary
When this stops being a self-service repair
- !If Bluetooth is missing from Device Manager after a driver reinstall and BIOS update, contact Acer Support
- !If no device pairs and Wi-Fi also fails, book a service check
- !If only one accessory fails on every computer, contact the accessory maker

Exact questions
Common questions
Does the Predator or Nitro use a different Bluetooth stack?+
No. Both use the standard Windows Bluetooth driver from Acer or Windows Update, so the steps on this page apply to all four laptops.
Can a USB 3 hub disturb the link?+
Yes. USB 3 devices near the antenna can add noise on the 2.4 GHz band, so unplug them while testing.
Why do my headphones cut out when I use the touchpad?+
A weak signal or a crowded 2.4 GHz band can cause it. Move the router to 5 GHz, keep the laptop's antenna area clear and update the wireless driver.
What does Microsoft say is a common Bluetooth cause?+
An outdated or incompatible driver. You can update it in Device Manager by choosing the Bluetooth adapter and Update driver.
Why does my Bluetooth keep disconnecting?+
Microsoft has a separate article for it; the usual causes are power saving on the adapter, interference and drivers.
Why is there no sound from a connected headset?+
Microsoft has an article for Bluetooth connected but no sound; choose the headset as the output in Sound settings.
Do gaming Acers have separate Bluetooth?+
They normally share a wireless card with Wi-Fi. A fault in both points at the card; one alone points at pairing or drivers.
Is Bluetooth switched by a key?+
Some Acer laptops use a function key or airplane mode key for wireless. Check the keyboard and Settings.
Will a BIOS update help?+
Sometimes. Acer publishes BIOS and wireless driver updates for each full model number.
Do I need a part number for a Bluetooth repair?+
No. Acer identifies the laptop by its full model number and SNID.
What does a Bluetooth repair cost?+
A Bluetooth fault is nearly always pairing, a driver or a setting, which costs nothing. If the wireless card is at fault, an independent shop repair is typically $99 to $299 with a free diagnostic, per BadgerLayer's 2026 laptop repair guide.
