Why does my Acer computer Bluetooth keep disconnecting all the time?

Technician avatar Technician
Let’s start by narrowing down what’s happening with your Acer Bluetooth.

When your Acer computer Bluetooth keeps disconnecting, it can be due to several factors like interference, driver glitches, or power settings. Sometimes the problem begins after updates or changes in hardware.

Before any change, can you tell me when this started? Was it after installing a program or Windows update? Or did it just begin suddenly?

Also, do you notice if the Bluetooth disconnects only with one device or multiple devices?
Customer
It started a few days ago. I didn’t install anything new, but I think Windows updated automatically. It’s mostly my wireless headphones that keep dropping out, but sometimes my mouse too.

Thanks for that info. Windows updates sometimes reset or disable Bluetooth drivers or change power management settings.

Let’s check a few things safely:
• When the Bluetooth disconnects, does it reconnect automatically or do you have to manually reconnect?
• Is your Acer laptop plugged into power or running on battery when the drops happen?
• Are your Bluetooth devices fully charged and close to the Acer when disconnects occur?
Customer
Usually it disconnects and reconnects on its own after a few seconds. It happens both on battery and when plugged in. The headphones are charged and really close, but the mouse sometimes works fine and sometimes drops too, even when right next to the laptop.

That suggests it might be a driver or power setting issue. Sometimes Windows tries to save battery by turning off Bluetooth devices.

Next safe check: open Device Manager (you can search for it on your Acer), then find Bluetooth, and right-click your Bluetooth adapter. Do you see an option for Properties? If yes, check the Power Management tab and see if “Allow the computer to turn off this device to save power” is checked.

If it is, uncheck it to prevent Windows from disabling Bluetooth when idle.
Customer
Okay, I see that setting. It was checked, so I unchecked it. Should I restart now?
Technician avatar Technician
Yes, a restart is a good idea after changing power settings to make sure they take effect.

Also, consider checking your Bluetooth driver version in Device Manager. Sometimes the driver updates automatically and causes instability. You can try to roll back the driver if the option is available, or check Acer’s website for a stable Bluetooth driver matching your model.

But before that, let’s confirm if this change improves the situation.
Customer
I’ll restart and try using the headphones and mouse again. What if it still disconnects?
Technician avatar Technician
If the problem persists, another common cause is interference from other wireless devices or USB 3.0 ports nearby, which can disrupt Bluetooth signals.

Try moving other wireless devices away from your Acer or use the Bluetooth devices in a different area.

Also, check if any Windows updates are pending to install or if your Bluetooth driver has a recent update that might fix bugs.

Finally, removing and re-pairing the Bluetooth devices can sometimes clear connection glitches safely.
Customer
I noticed the mouse drops more when I have a USB hard drive plugged in. Could that be the reason?
Technician avatar Technician
Yes, USB 3.0 devices can cause interference with Bluetooth signals, especially if they are very close to the Bluetooth adapter inside your Acer.

Try unplugging the hard drive temporarily and see if the mouse connection improves. If it does, you might want to reposition the USB device or use a USB extension cable to keep it further away.

This is a common issue and easy to test without any risk.
Customer
That’s helpful. What about Bluetooth settings in Windows? Should I change anything there?
Technician avatar Technician
Generally, Windows Bluetooth settings are straightforward. Make sure Bluetooth is turned on and your devices show as connected.

Avoid toggling the “Allow Bluetooth devices to find this PC” setting unless you know why it’s needed.

If your Acer has a Bluetooth troubleshooter, running it can help identify issues without changing anything important.

For now, focus on driver and interference checks first.
Customer
I’m a bit worried about messing up something. Is there any safe way to check if my Bluetooth driver is causing the problem?
Technician avatar Technician
Yes, you can do this safely:
1. Open Device Manager.
2. Find your Bluetooth adapter, right-click and select Properties.
3. Go to the Driver tab.
4. If “Roll Back Driver” is clickable, that means Windows saved the previous driver version. Clicking this will revert to the older driver without deleting anything.

This is a safe step that can fix issues caused by recent driver updates.

If Roll Back is greyed out, you can note the driver version and check Acer’s website for updates or advice.

Accepted fixes: what to check when Acer computer Bluetooth keeps disconnecting

Key first steps for Acer computer Bluetooth keeps disconnecting:
• Check if power management is allowing Windows to turn off Bluetooth devices; disable this option.
• Restart your Acer after any setting changes to apply them.
• Look for interference sources like USB 3.0 devices or other wireless signals nearby and test without them.
• Use Device Manager to roll back or update Bluetooth drivers safely.
• Remove and re-pair Bluetooth devices to clear connection glitches.
These are diagnostic and low-risk steps to gather clues and possibly improve connection stability.

Common reasons why Bluetooth disconnects on an Acer computer

Bluetooth can be tricky because it relies on wireless signals that are easy to interrupt. Common causes for your Acer Bluetooth disconnecting include power-saving settings that turn off the adapter, driver problems after Windows updates, and interference from other devices like USB 3.0 ports, Wi-Fi routers, or even microwaves. Sometimes the issue is the Bluetooth device itself, such as low battery or outdated firmware. It’s important to check each of these areas carefully to understand what’s affecting your Bluetooth connection.

What to check first when your Acer’s Bluetooth connection keeps dropping

Begin with simple, safe checks that don’t change anything critical: verify if power management settings allow Windows to turn off Bluetooth devices, confirm your Bluetooth device is fully charged, and try disconnecting any nearby USB 3.0 devices that might cause interference. Also, look in Device Manager for driver issues or recent updates. Avoid resetting network adapters or reinstalling Windows until you gather more information. These steps help pinpoint whether the problem is software, hardware, or interference related.
