Hi,

I have spent hours on this issue of touch screen problems with Windows.  I own quite a number of tablets that I use in my classroom with my students and I would say that upwards of 80% of them will have touchscreen issues.  It does not matter what make they are, Chuwi, Teclast, Alldocube, you name it.  Some of these tablets have a touchscreen.gt file and some do not.  On some tablets you have to manually place a system file  in the right location to have the touchscreen work at all after an upgrade.

But your problem is not that the touchscreen does not work but that it is inverted.  This is compounded by the fact that you are aware that touchscreen.gt can be modified to fix this issue, but that your tablet does not have this file.  So all that I can offer you is to say that given my experience, not all tablets even have this file to begin with.  And of course, the tablet calibration software in Windows 10 does not work.  Or at least I have never seen it work on any of my tablets.

So what to do?  I would get the original firmware file for your tablet off a rom site or Tech tablets and just start over.  Accept that you might have to not upgrade your tablet to the latest and greatest Windows 10 release or keep trying to upgrade until you get it to work properly.  I will follow this thread and maybe someone else will have a solution.

I followed a guide similar to this on youtube.  Was not a guide for the x80 pro yet everything worked.  No more android just a lot more room for Windows.  Very happy with the result because dual boot does not work if you want to keep windows updated.

Hi,

No need for another copy of Windows.  You already own a digital licence with a key that is embedded in the ezbook’s bios.

Just follow any of the guides that are in this forum or even a youtube video will do the trick.  Use doubledriver to do a backup of your existing install’s drivers and produkey to get your windows key and away you go.

Oh you will need a thumb drive say 16 gig in size. Use rufus or Windows media creator to turn create the media you need to do the clean install.  Anyway I’m not doing justice to the steps involved by just giving an overview like this.  A step by step guide is what you need.

Be careful with the bios in the ezbook 3 pro.  If you switch off quiet boot you can see the bios splash screen and it shows “evaluation copy.”  You might be better off sending it back than messing with it.

Hi again,

Something odd happening with my ezbook 3 pro:  just recently no matter what I set my display settings to the screen always goes black after one minute.  Running on battery, display set to “never” turn off, if I let the darned thing alone for just a minute, the screen is OFF.

Will I be posting soon that my unit won’t boot?  Stay tuned.

[Joe]

Lots of threads about this.  Search “black screen” and exbook 3 pro.  There is no solution, sorry to say.  I was hoping that it was a Windows software problem and that running Linux would be a possible solution.  I guess not.  Hardware problem and no Jumper support whatsoever.  Sigh.

Hi Ostap,

I think the word must get out somehow.  Gearbest will allow moderately critical reviews to stay on their website but I seriously doubt that a review that says the laptop has serious display issues from a number of users will be allowed to stay up.  You will need to only write about your own issues.

[Joe]

Hello everyone,

What a sad topic this is!  I wish I knew how well the Ezbook pro 3 was selling because then there would be some kind of context for these back screen complaints.  What I mean is, what percentage of these units have this problem which essentially renders this laptop unusable and impossible to repair?

Cold comfort for those who have the problem, I know.  But you would think that Jumper would have something to say about this or there would be someone on this forum who would report back that they talked to a Jumper tech and he/she said to do such and such or that there was a 1 800 number to call etc.

The unspoken dark side of buying this tech direct from China is that when you get a bad unit you are going to be seriously out of pocket with very limited support from the manufacturer.  Or no support at all.  How many people take the plunge, buy something that stops working and then that great deal with the low low price ends up collecting dust somewhere in their household?

I think that over the last three years I have spent easily over a thousand dollars, I shudder to say maybe even closer to two thousand dollars on Chinese tech direct from China.  It has been on the whole an interesting and fun experience.  I have bought Cube, Teclast, Chuwi and now Jumper tech of all sizes and descriptions.  The prices for what you get are incredibly low.  Mostly everything I have bought has worked and continues to function properly.  Even the problems I have had have been interesting and I have learned so much about how computers work.

One last comment before I sign off on this topic and have nothing more to say.  I bought a Teclast x98 pro that had these problems about two years ago. There are many posts about “black screen” and sudden Windows 10 shutdown etc in the forum on this site.  I had black screen happen to me numerous times on that tablet.  There was a stickied thread about it with a lot of suggestions in the x98 forum.

Now the problem with this Teclast product was not nearly as serious as it is with the ezbook pro 3.  At least you could recover and even change a bios setting to cut down on the number of times you would get screen blackout.  You had a fighting chance to do something.  But I find it curious how similar the problem is to what people are experiencing with the ezbook pro 3.  Could this problem be one of Jumper not properly setting up the hardware to work with Windows 10?<b> </b>I never had a screen blackout when I was running Android on the x98 pro.  Pity that our ezbook pro 3’s are not dual boot like the Teclast x98.  I would be willing to bet that you would not have this problem running Linux or Android.  In fact, perhaps to avoid the possibility of this happening would switching to Linux be a viable alternative to Windows on this laptop?  Someone who knows more about OS software than I do would have to answer that.

Hi again everyone,

I did open my ezbook pro 3 v4 and everything looks really tidy and first rate.  I have looked at YouTube videos and reviews and more than one commentator has remarked about how the motherboard looks.  Everything is so well put together.  Even the battery is a quality unit, not one of those lithium bag looking batteries the-colour-of-the-stuff-inside!

I looked at the cables that go into or near the hinge and I would agree with Tony that this must not be the reason for the black screen problems some of us are having.  My cables look tidy and not in obvious distress. Nothing is catching on anything.  The hinge is tight, the all metal case is well put together.  Honestly, I’m so impressed with this laptop I would turn around and buy another one to replace it if it would die.

Well, maybe I wouldn’t buy it from Jumper!  So I think it would be great if everyone with the black screen problem were to just post when and where they bought their Ezbook. That might help to identify a bad batch.

[Joe]

I’m almost afraid to use my ezbook pro 3 v4. Too bad about your son’s Christmas gift, Tony.  That’s a heartbreaker.

Today I’m going to open mine up. A theory that one gentleman had was that the display cable gets all wrapped up in the hinge and gets damaged every time you open and close the darned thing. It’s worth a try. Wish me luck!

[Joe]

Sorry to hear about this Naomi.  I have read every thread about this problem and I have even pmed someone else who had it and I must say the news is very grim.

No one to my knowledge has managed to fix this.

Now that needs to be in its own paragraph because a problem like this is just that devastating.  We buy Chinese tablets for the fun factor, the low prices, for a lot of reasons but it really hurts when it breaks because sending it back is such a pain.  It is not like you can just hop in your car and do a quick return.

I would get in touch with your seller right away and work out some kind of deal.  Be it a return, a partial or full refund, whatever.  Don’t waste any more time on a “fix.”

[Joe]

Aside from hardware issues, you could try looking at two other things:

1.Your ezbook windows 10 power plan.  My ezbook 3 pro v4 defaults to “ultra performance” all of the time.  This runs the cpu at top speed constantly, as I verified by watching the speeds while just surfing.  I had two other power plans, “balanced” and “ultra battery saving” if my memory serves me.  I am typing this on a Teclast 10 s and I have tried to find these plans but no luck.  Could your ezbook be running a lot faster than it needs to?

2. A trick you might follow to condition the battery would be to run it down to nothing and then plug it in for 8 or more hours.  This might get the battery to run better.  At least I have seen this advice given on a Chinese forum for another tablet.

Anyway if it isn’t a hardware problem, these two tips might help.

[Joe]

Thanks a lot for these profiles.  I used Constantine’s profile and the display looks amazing!  I must have really screwed things up using Window’s calibration.  Before applying this profile, the display looked washed out.  I wish I had screen shots to show the difference.

[Joe]

Ok well it finally worked.  I noticed that with the default install on my ezbook after I enabled updates in services one update did not install properly.  So on a hunch, I reset the 1703 Windows install that came with the machine.

Afterwards, I would not let 1703 update and proceeded to do the standard online Microsoft download and install of 1709.  It took a very long time even though I had the power set to unlimited in the bios and my ezbook was getting quite hot, about three hours or so.  But it installed.  Finally.  What makes the ezbook 3 pro so hard to update?  Is this the reason why Jumper disables updating of Windows 10 by default?

[Joe]

I just finished trying to update to 1709 using the standard method from the Microsoft website.  Things seemed to be going well on my  Ezbook 3 pro v4 so I left it alone for awhile.  About 6 hours later I checked back and the blue power light was still on but nothing else was working.

I had to press on the power key until it shut down and then of course I wondered if it would boot again.  Luckily it did, but of course 1709 was not installed and I was back where I started.  I’m going to try a few things before I do it again.  Dos anyone know how to check a log file for the error that the update must have encountered before it gave up?  Or do such log files exist only for Microsoft?
