How to Reboot Power Bank Xiaomi Mi Power Bank 2 10000mAh: All the Ways

Xiaomi Mi Power Bank 2's 10,000mAh external batteries are legendary for their reliability and affordable price, but even these devices sometimes get stuck, stop charging, don't show signs of life, or freeze in a constant display mode. 90% of the time, the problem is solved by simply rebooting the internal controller, but many users don't know how to do it correctly so as not to damage the battery.

In this article, we will discuss all the working methods of rebooting Xiaomi Mi Power Bank 2 10000mAh (model PLM03ZM), including “hidden” combinations of buttons that are not described in the official instructions. Also explain why the device may require reset, and what to do if the reboot did not help. Importantly, the procedure for this model is different from newer versions (for example, Mi Power Bank 3), so watch for the designations on the case!

Signs that Xiaomi 10000 2 Power Bank needs a reboot

Don’t rush to bring the device to the service or buy a new one – often enough to “reset” the controller. to determine that the power bank is stuck and needs to reset, you can by the following symptoms:

• 🔋 Indicators burn constantly (all 4 light bulbs), but the charger does not go.
• ⚡ The device does not respond to the connection of the cable - neither to the socket nor to the gadget.
• 🔄 The light bulbs flash chaotically or show an incorrect charge level (for example, 1 fission with a full battery).
• 🛑 Power Bank is heating up for no apparent reason (but not to a critical temperature).
• 🔌 When connecting to the network, only the first indicator lights up and immediately goes out.

If you see any of these signs, the probability of a software failure of the controller is 80-90%. Physical damage (bloating of the case, the smell of burning) is another case that requires repair or disposal.

⚠️ Warning: Do not confuse freezing with deep discharge. If the power bank has been idle for more than 6 months, its battery could run to 0 V, and a normal reboot will not help.

Method 1: Standard button reboot (for most crashes)

This is a basic method that works 70% of the time, and it works if the lights are on, but the device is not giving up charge or is not behaving stable, and you only need the Xiaomi Mi Power Bank 2 and 10 seconds of time.

Step-by-step:

1. Disconnect all cables from the power bank (both input and output).
2. Find the on button on the case - it is located next to the charge indicators.
3. Press the button and hold it for 10-15 seconds (or rather, until all the indicators go out and light up again).
4. Release the button. The device will perform a soft reset of the controller.

After the reboot, connect the power bank to the charger (preferably the original from Xiaomi with 5V/2A output) and check the operability. If the indicators caught fire in normal mode, the problem is solved.

Method 2: Hard reset through full discharge (for "dead" devices)

If the power bank does not respond to the button at all and does not charge, there may be a failure in the non-volatile memory of the controller, in which case a forced discharge to zero will help, followed by “flashing” from the charger.

Algorithm of action:

• 🔌 Connect to Xiaomi Mi Power Bank 2 load – for example, a smartphone with a discharged battery or LED-lamp (through USB-adapter).
• ⏳ Leave the device in this state for 12-24 hours, so that the battery is discharged to 0%.
• 🔋 After full discharge, connect the power bank to the original charger (not to the original charger). USB-PC port!) and leave for 6-8 hours.
• 🔄 Try to turn the device on with a button. If the indicators catch fire, the reset is successful.

This method works because the controller TI BQ25703A, The one installed in Mi Power Bank 2, which resets errors during deep discharge and subsequent charging from a stable source. USB-powerbank.

⚠️ Warning: If the device does not start charging after discharge, check the integrity of the cable and charger. In rare cases, the problem may be a circuit break inside the case - then you will need an opening and soldering.

Method 3: Reset via button combination (hidden function)

Few people know, but the Xiaomi Mi Power Bank 2 has a service menu available through a special combination of taps, which helps when the standard reboot does not work, but the indicators are still showing signs of life.

How to activate:

1. Disconnect all cables from the device.
2. Press the switch 5 times in a row (with an interval of ~0.5 seconds).
3. After the fifth press, hold the button for 8-10 seconds.
4. Release the button. The indicators should flash in a non-standard sequence (for example, 1-3-2-4), signaling a reset.

This combination resets the controller calibration, which is especially useful if the power bank shows an incorrect charge level, for example, when after full charging after 5 minutes of use, the indicators fall from 4 to 1 division.

Table: Comparison of resetting methods

To choose the best method, focus on the symptoms and degree of "hang" of the device. Below is a comparative table of the effectiveness of each method.

If none of the methods worked, there is a possibility of hardware failure (for example, failure of the BQ25703A chip or breakage of the tracks on the board), in which case repairs will cost less than buying a new power bank only if there is a guarantee.

Method 4: Reboot via PC connection (advanced method)

This is a way for people who are willing to spend a little time diagnosing, and it requires a Windows or Linux computer, USB-cable and special utility MiPowerBankTool (developed by enthusiasts for Xiaomi devices).

Instructions:

1. Download the utility from the official GitHub repository (check that the version supports Mi Power Bank 2).
2. Connect the power bank to the PC through USB-cable (use the port) USB 2.0 for stability).
3. Run the utility on behalf of the administrator and select the Reset Controller option.
4. Follow the instructions on the screen. The program will send the device a command to reset via the USB HID protocol.

The advantage of this method is the ability to see the actual state of the battery (voltage, number of cycles, temperature). For example, if the utility shows a voltage <2.5V, the battery is deeply discharged and requires "resuscitation".

💡

If the utility does not recognize the power bank, try to connect it through USB-It's an externally powered hub, and sometimes the controller doesn't have enough power. USB-PC port for initialization.

What to do if the reboot does not help?

If after all the manipulations Xiaomi Mi Power Bank 2 still does not work, check the following points:

• 🔌 Cable and Charger: Use Xiaomi’s original Quick Charge 2.0 cable. Cheap cables may not provide the right current to “wake up” the controller.
• 🔋 Bloating: If the power bank gets thicker or there are gaps on the case, the battery swells and needs to be replaced!
• 🛠️ Contact oxidation: Disassemble the case (carefully pulling the lid with a plastic card) and check the board for oxides or cliffs. Often the problem lies in the soldered wire from the battery.
• 📱 Controller firmware: In rare cases, flashing the chip through the programmer (for example, CH341A). This is a complex procedure that requires rationing skills.

If you are not sure of your abilities, contact the Xiaomi service center (if you have a warranty) or the electronics repair shop. The average cost of diagnosis is 300-500 rubles, repair (replacement of the controller or battery) will cost 800-1500 rubles.

💡

Before visiting the service, try resuscitation via a Pre-Charge charger (such as the iMax B6) that can rock a deeply drained battery that standard RAMs don’t see.
