Can you replace a battery in a tablet? That’s a good question. It’s almost always possible. The question is whether tablet battery replacement is practical. Some companies make it really easy to replace a battery, and some make it really hard.
My son told me one morning that he’d let his tablet charge overnight, but the battery level was at 60%. I messed around with it, and indeed, it seemed that the battery had lost its ability to charge with the wall charger. Here’s how I fixed it.
It probably was just a matter of time, but one of my sons dropped his Asus Memopad HD 7 and cracked the digitizer assembly. What we usually call the screen actually sits behind the breakable piece of glass, and more often than not, it’s the glass digitizer that breaks. I left it that way for a while, but once the screen cracks, the cracks tend to spread, and eventually the tablet will get to a point where it’s unresponsive.
Replacement digitizers are available on Ebay. Note the exact model number of your tablet (my kids have ME173Xs, so here’s an ME173X screen) because they aren’t all interchangeable. The part costs around $20. It took me about three hours to replace because it was my first one. If I did this every day I could probably do it in 30 minutes, and I’m guessing if I have to do another–ideally I won’t–it will take an hour or so.
I’ve written enough about the Asus Memopad HD 7 that you can probably surmise I’ve had a few issues with them. Fortunately the fix is usually simple, and in the case of a Memopad that won’t charge even after you did my battery fix, that’s true as well.
It started with my observation that the USB cable fit rather loosely into my sons’ tablets. I cleaned out the mini-USB port with a wooden toothpick, which is a common fix, but it didn’t help–the cable still fit very loosely and the device wouldn’t charge.
Then I tried other cables. I found most of them didn’t work either. If I set something heavy on top, they would charge for a while, but doing that caused the cables to wear out in a matter of weeks. Finally I figured out the tablets are just picky–or at least they are once they get some age to them. The charger for the Moto E, which has a hardwired cable, works fine. So does some other random cable I had that I never used for anything else because it happens to be so short it’s not useful for anything else. I bought some new Monoprice cables, and while they’re fine for data transfer, these Memo Pad 7s don’t like them for charging.
I really hate to say try every USB cable in the house, but… your best first step is to try every USB cable in the house. And if you have to buy a cable, buy something locally, ideally in a store that will try it out with you before purchase. If you don’t have a store with that kind of service near you anymore, then buy a cable and try it out in the parking lot in your car right away before driving home. That way you can exchange the cable right away, or get a refund, if it doesn’t work any better than what you already had.
My son’s Asus Memopad 7 HD would not power up or charge, and my earlier non-invasive solution wouldn’t fix it. Here’s how I opened it up to disconnect and reconnect the battery.
Always try holding the power button and volume down button first because that’s easier (see the link above for details), but if that doesn’t work, proceed to open the case.
While you’re in there, you can also fix an issue that may be causing the power or volume buttons to be hard to press or malfunction entirely. Dropping the tablet a lot makes this happen. If you have young children, you probably understand.
Another malady these tablets can develop is a battery with a question mark when charging. This will sometimes fix that issue as well.
One night my son ran down the battery on his Memopad 7 and put it away, but didn’t put it on the charger or tell me about it. The next time he went to use it, it was dead.
I tried several different tricks I found online, including plugging it in overnight to the AC adapter, plugging it in overnight to a computer’s USB port, and holding down the power button for a full minute or even a full five minutes. None of it worked–the unit just wouldn’t power on or show any signs of life whatsoever.
Finally I resigned myself to the possibility I would have to send it in for service. Read more
I’ve been messing with an Asus Memopad, the 7-inch version. I think it’s a well-built, good-performing tablet for $149, and when you can get it on sale for less than that–and this is the time of year for that–I think it’s a great tablet for the money.
It’s not a high-end tablet. It has a 1280×800 screen, a quad-core 1.2 GHz Mediatek processor, a middling GPU, and 1 GB of RAM, and importantly, it includes a micro SD slot so you can add up to 32 GB of storage to it. The specs are all reasonable, but not mind-blowing. Most of the complaints I’ve seen about it are that it’s not a Nexus 7, but it’s 2/3 the price of a Nexus 7, too. When you compare it to other tablets in its price range, the worst you can say about it is that it holds its own. Read more
