The following email from Teclast shows the company couldn’t care less about standing behind their product.

It’s hard for me to believe they can’t even help me source a battery. Not asking for a freebie but just want to get the right parts.

No more Teclast for me.

Hi, <wbr />Ralph.Thank<wbr /> you very much for using our company’s products. It is a pity that we do not set up a separate retail of accessories abroad. Thank you for your feedback.

<b>Subject:</b> Replacement Battery for the Teclast F6 Pro

The battery in my Teclast F6 Pro laptop just died after 18 months of use. I need to buy a replacement battery for it and would like to know if Tesclast sells replacement battery for the F6 Pro.

If not, can Teclast recommend a store or company to me with the information where I can buy a replacement battery for my laptop.

I think I’ve reached the end of the road trying to repair the F6 Pro myself! I tested the PS board and it’s working and providing 12V to the Mboard. Checked all the flex connectors and they all appear to be working. So all lead to the MB. Whether it’s fried or a dead capacitor somewhere, I don’t know…..

If I can source a MB for the F6 Pro, I will get one. So if anyone has a working F6 Pro MB they want to sell, let me know…..

**Update***

Received a new battery today. After replacing it still NADA, no battery or SSD status light. So it’s not the battery in my case. The only possible problem I can see is the power adapter circuit board.

Now the big issue is where to source a similar board for the F6 Pro.  I’ve been looking high and low with no results. So if anybody knows where to source parts for the Teclast or has defective/dead one and wants to sell parts, I’d be interested in that as well.

I’m not sure whether it’s the battery or power supply .As mentioned in my original post, when the laptop first went dead, there was enough juice to charge my tablet, than my phone, which leads me to believe battery is good! Never had an issue with battery not fully charging or discharging abnormally. So I’m assuming the battery is not the cause . The power supply could be the culprit, so now got to research to find out how to change it this laptop .

@katagiri, it’s on the first page of this post about half way down .

If you search my username you will find a small write-up with pics for opening up the X6 Pro . The mod does wonders for the thermals, no more throttling. I have a teenage son that pushes hard all the time and the thermals are steady solid .

**UPDATE****

It seems the laptop is completely dead! I disconnected the battery and plugged in the AC directly and nothing!! No LED status lights, screen did not wake-up, no boot up, NADA!!!!

I’m pissed and concerned at the same time, considering that I have an X6 pro as well and wondering if it will suffer the same fate after 18months!!

I contacted Gearbest support/customer service, but I don’t expect them to do much . They are asking me to send them pictures to diagnose the problem!! Pictures of a dead laptop that doesn’t power up to help diagnose a hardware issue left me dumbfounded !!!

Update 08 Feb.2019: I finally opened the tablet to do the heatsink mod, an old Xbox gift card was the tool of choice. Teclast gets a BIG FAIL on my unit (see attached pics). There was no cooling paste on the CPU/GPU, just a super cheap paper thin 1/2″ thick cooling pad was on top of the CPU. I guess quality control must have been sleeping on the line on that day. I have some 1″ pad and they were definitely twice as thick as the factory one, which would explain why my X6 Pro would get to 90C zone . After the mod, stress test would only bring my unit as high as 55C, so a good 35C difference, so worth the mod. Playing games or Netflix, having multiple tabs opened while multi-tasking, keeps it at around 45C. WARNING*** When opening up the tablet, please make sure that you remove the screw holding the SSD to the back cover or else you will brake it. Also when re-assembling the unit, the keyboard connector has to be at a slight angle so it can fit properly******

thank you! please share the after pic when you applied the new pad.

Sorry for my lack of clarification. I did use 1 copper shim+pad on top of the CPU/GPU and a larger pad on top of the OEM heatsink to distribute more heat. The result being the back cover is hotter to the touch but nothing excessive. I took pics of the stress test post heatsink mod and they are attached in my other post.

<!–more–>I agreed with you Chris I’m also confused either to go with teclast x6 or ubook

For what it’s worth coming from an average techy person, this tablet will never be a Surface Pro. Teclast has some ways to go before calling it a Surface Pro killer. I have compared it to a friend’s M3 Surface Pro and I don’t think it is a bad deal at all for what you are paying for ! When compared to other Chinese manufacturer 2in1 tablets out there, I think this 7th Gen core M3 from Teclast is a winner for me and better than the rest so far when comparing apples to apples!

Today I had a chance to do some stress tests using XTU to get some quantifying numbers. To start my set up is the following in the BIOS;  PL2 @ 9w and 12W, system is undervolted to -70mv as well as the GPU at -70mv. So far the system has been stable with no crashes or freezes during or after the stress tests.

During the GPU stress test, system experienced some power limits throttling and temp went as high as 81C, but no thermal throttling.

During the CPU test, there was no power limits throttling or thermal throttling. Temp went as high as 75C.

When the system is not being pushed, thermals go back to 45C

Attached are the results for the X6 Pro and I would assume that will hold true as well for the F6 Pro. Since I have an F6, I will try those numbers on it later.

So my conclusion is for my needs, the heatsink mod is well worth it for the X6 Pro.

I ordered mine from Geekbuying as well and it took 3 weeks from date of order from their warehouse to get it in my hands in Canada.

Overall I’m happy with it. Things I’ve noticed so far;

• Some light bleeding around the screen edges
• Speakers could be better
• Thermals might become an issue  when pushed hard. With some moderate multi-tasking temp can go up to 90• C.
• Battery is worse than the F6. With screen brightness at 35% and a lower resolution, I’m getting 4-5hrs at best! That is disappointing!
• BIOS is unlocked like the F6

Like my F6 pro it is undervolted and OC with throttlestop. I’m also running CPU Core Parking as well .

I’m tempted to open it up like my F6 to see if a copper mod might be in order.

Thanks for the X86 info, I’ll give it a try later this weekend.

Tres apprécié. Merci pour avoir pris le temps pour expliquer

Can we try to use translate please?

I was asking “Pipolitoto” to post a how-to/link on how he managed to dual-boot Android7 and Win10 on the F6 Pro.

[Winston]

J’ai la même question que “Seeb”. Peux-tu mètre la procédure pour opérer en multi-boot? Ce serais super de pouvoir opérer Windows et Android 7 sur le F6 Pro.
