What's Worth Picking Up: Repairing the Lofei MT-200 Touchpad

Hello everyone, I am the only brother who insists on both price and quality, and I am also a civilian commentator who is worth buying without signing a contract. It has been a long time since the last creation, mainly because I changed jobs in the past year. From a step-by-step management position to a bloody sales position, there are too many things to learn, and there is no time to toss and write. There are more opportunities for home and business trips in new positions, and mobile office has become a real need instead of pretending to be high. After thinking about it, it is most suitable to buy a tablet. The battery life is long enough, and you can hold video meetings or write reports. The most important thing Well, it’s still convenient for iQiyi...

In 2023, I still use my mate40pro. Except for the poor battery life and negative photo optimization, there are no other problems without the family barrel. Especially after several upgrades of Harmony OS, I feel that Huawei is more and more attentive in office, so the tablet Also naturally chose matepad. Facts have proved that matepad11 is indeed suitable for office work, multi-screen collaboration, Huawei sharing, PC version WPS, surprises continue. With a tablet, it is natural to add several accessories, such as a protective case, a tablet stand, an expansion dock, and a suitable portable mouse button. Although the individual items are not worth much, they add up to a lot of money. Especially the cheap ones dare not buy portable mouse keys, and the fancy ones are not cheap, at this moment...

Isn't it an eye-catching solution? Luofei's touchpad can replace the mouse, has a full keyboard, and is portable. We don’t know if Luofei’s products are good or not, but they are really expensive. This touchpad is 29 yuan with free shipping. Unfortunately, the person who broke the news said that it was in stock many years ago, and the battery is broken. After a lot of effort, I found a seller in the seafood market, and the seller repeatedly reminded that the battery was bad. Can changing the battery be a problem for the only brother with strong hands-on ability? Of course, for the sake of stability, my great cleverness still took two shots, just in case I was handicapped and brain-dead.

Enter the official content of this article below...

First of all, let's appreciate the sloppy packaging: Luofei MT-200 wireless touchpad is compatible with win8, and actually win10 is also compatible. Accessories are simply a micro usb charging cable and wireless receiver and the touchpad itself.

Look at the touchpad again: the brand new stock is gone, the film is still there, and the function is normal, but this bulge...

The repair process includes dismantling, confirming the battery model and wiring, buying a new battery, welding and restoring. I adjusted the order of the restorative process for the convenience of friends.

In my experience, the screws are usually hidden under these strips. You see, you guessed it, this asymmetrical screw slot makes me uncomfortable. There are screws on the top, but not on the bottom, so the bottom rubber strip can actually be removed without removing it.

Then we insert the crowbar from the bulging part, cut the panel clockwise, pay attention to the buckle at the bottom, and carefully pry it off one by one. After prying around, it was found that the panel could not be separated. I guessed that there was a screw integrated with the panel inside, and the screw could only be withdrawn by rotating the panel. Before that, let's remove the cable to avoid twisting the cable. Find a toothpick to remove the crimping clip of the cable. It is not very easy to operate. Fortunately, my fingers are too thin, and the clip is only broken on one side and can still be used.

When turning the screen, the touchpad should be placed flat, so as not to dislodge the micro switches like I did, it took a lot of work to find all the parts and restore them.

Come on, let's look at the battery. Ordinary 402030 batteries, the original ones are only 180mAh, and I bought two 200mAh 402030 batteries on Taobao, which cost another 10 yuan.

No welding skills, slightly.

Finally put it back, here I destroy the screw eye integrated with the outer screen to facilitate the next repair. By the way, the vibration in keyboard mode is very annoying. I disconnected the rotor motor.

Well, let's try it out, the lighting is ok, the charging is ok, the battery life is ok, and the touchpad and keyboard mode switching is ok.

This article is over, thank you for watching, welcome to reward.

By the way, when I showed off to my daughter, my daughter asked me: "Isn't the tablet already capable of touching and typing, why do you need a touchpad?"
