How to repair a Chinese tablet which wont turn on or charge

Chinese tablet

Lately, many people have been buying tablets from China because of the low price and easy accessibility of Chinese products.  Though these products are affordable and easily accessible; unfortunately, some of the tablets are of low quality with very high chances of becoming faulty.

There are different types of possible faults, but I have seen many tablets with the same problem. The most common problem with Chinese tablets is that most of them won’t charge or turn on or even boot.

However, in this how-to guide, I will be showing you how to fix a tablet that won’t turn on or charge. As I stated earlier, this is a common problem with Chinese tablets, and I am ready to work you through a step-by-step procedure on how you can fix such a tablet for yourself, friends and family.

How to detect the problem

Detecting the problem of some of these Chinese tablets is not far-fetched. You only need to notice the abnormal performance once you start using the gadget. Some of these issues develop slowly until they become so unbearable and disgusting at the same time. Also, some of these Chinese tablets’ problems are aggravated by using the wrong accessories on them.

Another essential thing that will help you detect the fault in your gadget is observing if your device’s charging rate has slowed down over time from the time of purchase. And probably if your tablets now hang more often than necessary.

So if you have any of this problem with any of the tablets from China and you have tried too hard to reset the device. Then, I have a solution for you in this guide.

The DIY and easy-to-follow solution for your Chinese tablets

There is no doubt that Chinese tablets are good alternatives for other costly tablets in the market. However, the incessant faulty they develop makes them less quality to most other tablets out there.

And if you have detected any of the problems on your tablets- maybe it’s not turning on or charging, then follow me as I unravel the DIY fix before decoupling or even taking it to a technician. The tablet can be an easy fix for you because sometimes it might only be an issue with the battery.

Sometimes the battery freezes and does not recognize the charger. And at other times, the power on and power off functions could be the ones with the problem. Either way, you have to cross-check and ascertain which of them is responsible for the problem.

Moving on, before you do anything carefully, try to charge the tablet with another charger that you can attest that is functioning 100%. Doing this will help you confirm if it’s a faulty charger or maybe the charging port. But kindly use a charger that only has the same output voltage.

After doing all that, if the tablet still doesn’t work, then you should try to connect to a computer via a USB cable. Charging with a USB cable will help understand the nature of your gadget’s problem without any stress. However, suppose the tablet now refuses to work correctly even after connecting to the computer via a USB cable. In that case, unfortunately, your charging port will be at fault, and you might need to decouple your tablet eventually.

Ideally, I won’t recommend that you open your tablet all by yourself because of the technicality, expertise, and high level of carefulness you need to maintain. Nonetheless, since it’s a DIY guide, you definitely can do it, and with my guidance, you will be able to do it.

Now that you have decided to open your tablet, you have to carefully open it up to avoid causing more damage to the device. If you are not careful enough, you might end up damaging your screen- and this will be more painful and even difficult to repair.

A quick point of attention- most tablets do not come with screws; they have holders. So sometimes it doesn’t prove easy to open such devices. However, with the right tools at your disposal and your readiness, you can do it. Moreover, many videos on YouTube teach and show easy-to-do tutorials you can watch to achieve your aim.

Okay. When you open the tablet, it will look something like the photo below.  The first thing you have to do is check the voltage and amps of the battery. If voltage or amps are zero, then you need to try directly charging the battery with a li-on charger. Please only use the appropriate charger to do this because the battery can explode if you use the wrong charger.

Once you have ascertained that the battery is okay, then let’s continue. You should check the motherboard, and you would see that the battery is connected to the motherboard with two wires. While one of the wires is red, the other is black. You will need to disconnect the red wire from the motherboard. To do this, carefully use a soldering iron and endeavor not to tamper with any other thing.

Tablet motherboard repair

When you have disconnected the red wire from the motherboard, then you need to put the red wire somewhere isolate where it is not touching anything. After that, all you need is to connect your Chinese tablet to a charger only for a few seconds. When the tablet is charging, it may show sparks and try to bring the battery backs to life.

After a few seconds, disconnect the charger from the tablet and reconnect the red wire to the motherboard. When you do that, try to turn on the Chinese tablet. If the problem was only in the battery, the tablet should work, but if the problem is somewhere else like on the motherboard, then, unfortunately, the tablet will not work.

Conclusion

Chinese tablets are affordable and easy to come by. And in all honesty, they are excellent alternatives for other expensive tablets on the market. Since the tablets are not too pricey, they tend to be less quality and highly problematic.  But you can follow the stepwise procedures highlighted above to repair your Chinese tablets by yourself.

    This worked for me. I de-soldered the red wire, left it for 60 seconds then plugged the charger in and pressed the power button. The tablet booted. I soldered the wire back on and the tablet is working fine now. Thanks for the tip!

      If the screen is broken, then you need to buy a new lcd screen.

    Thanks for this guide!!

    I’ve tried with a chinese tablet and I desoldered the red wire and connected the power adapter and the tablet turned on and left connected for ~60seconds, disconnected the power adapter, soldered the red wire and again I connected the power adapter but the tablet wont turn on

    I think that the battery it’s deffective, I’ve no tried yet but it’s possible to charge directly the battery with power adapter 5v 2000mA?

    Do you know of any website that supply new batteries for broken Chinese made ones, like batteries for the Chuwi DX1 with the rotating camera? The manufacturer support is below par, and the retailer is in HK, so all very difficult to fix the otherwise perfect tablet. It just won’t boot up any more.

    Hi ! Thanks for all this information. Unfortunately, I don’t see it helping me with my problem. My Chuwi Vi8 dual-boot stopped working after I reverted back to Windows 8.1 from Windows 10. At the time, both Op. systems worked fine. Since, I keep getting a boot loop when I turn it on and it doesn’t stop until I hold the on/off key for a few second after it shuts down. The message I received is: 🙁 Your PC ran into a problem and needs to restart. We’ll restart for you. If you’d like to know more, you can search online later for this error:
    INACESSIBLE BOOT DEVICE.

    I’m no wizz at this stuff, so I don’t know what to do to get my tablet working. Has anyone had this problem? Can anyone offer any help? Thanks in advance. Appreciate anything you can do. Lou

    This worked for me. Mine is a Chuwi V88. Tks a lot. I had already tried everything else and had already bought a Hi10. I gave this V88 it’s last chance to live and it did. This V88 was headed to the garbage if this last attempt failed.

    I disconnected the red wire, plugged it in and it lit up immediately! So I let it run for a few seconds, then unplugged it, resoldered the red wire and plugged the charger back in. No reply…..

    Should we leave it plugged in when we resolder the red wire? That seemed to be what some people did for whom it worked.

    Thanks!

    Hey
    My tip- before opening the tablet is to re-calibrate the battery.
    I have a Chuwi iv10 and it work for me.
    I just go into BIOS setting by pressing ‘Esc’ key when
    Chuwi chinese writing logo appear when booting,
    Left it on for approx 45 min until it powered off because battery is completely drained.
    Then charge it (tablet stays off) until 8-9 hours.
    Mission complete .

    Hi.
    My cube Talk8 has booting problem in that it boots endlessly.
    Problem started during a factory reset as battery ran out before completion.
    The battery still charges to 100%, but it boots but does not on.
    Tried factory reset again but will simply boot endlessly
    What can be done please?

    I bought a broken Cube iWork10 tablet that would just briefly flash the blue LED when the power button was pressed and this fixed it for me. Thank you so much!
    After resoldering the battery I just had to leave it plugged into the USB-C charger for about 10 minutes (the charge LED didn’t light up during this time). After about 10 minutes the blue charge light began blinking and it powered on as normal.

    hi,
    I did like you said, it worked again. but after I charged my tablet, charging light continue blinking and I couldn’t turn on again. I unplug and re-solder the red wire and worked again but, after I charged, again don’t turn on. I need to unplug and solder again after every charge. What could be the problem? what can I do to solve the problem.

    Johnny, My Sur-Book battery went to 0% before I could charge it; And now I’m having the problem of not charging!
    It sounds like you are trying to charge the battery directly connecting to Red wire (un-soldered) And so you are by-passing the USB-C charging Port is this correct?
