Display not illuminate

[Henrik Rintala]

Just got today the Cube Thinker I ordered for my daughter for school. It didn’t seem to turn on. I charged it (red light until it turned green). So looks like battery charging works. When turning it on (without power cable attached) the led blinks very shortly in green and nothing happens. Manual says to press power button for three seconds to turn on the machine (with help of google translate). If I hold the power button pressed for a long time after maybe 20 seconds there is a brief red flash of the led (reset?) but machine is still not turning on.

If the power cable is attached then the left USB port is getting power (charging my bluetooth headset works there) but right USB port is not getting power.

Could anyone with a working one see if the right port is getting power?

Could there be any loose cable inside? Opened up the back lid but didn’t see anything looking loose. If the other USB socket should give power when charging then that might be the place to look…

Update: left USB port is only charging my bluetooth headset, my iPhone 5S does not get any power so there is some voltage at the USB port when charging but not enough to charge a phone. (Obviously the notebook is turned off since it will not power on).

Disconnected battery power cable from mainboard and plugged back in – didn’t help. Now thinking whether to return it for replacement (not ideal) or trying to reattach all cables to see if it would solve anything…

I think I have the same issue. You have to be patient. After pressing the power button for 3 seconds, it may take up to 20 seconds for the logo to appear. Then it will reboot again and takes again a long time, but eventually it will boot into Windows.

If you don’t turn the laptop off, but only in Windows sleep mode, it turns on immediately (obvious), but of course drains the battery…

Really wondering what’s going on.

Thanks for the tip. I tried it again with power cable connected and without it. Pressed power key for 3-4 seconds and then waited. Unfortunately nothing happens even after about 2 minutes. Without power cable connected the LED next to the power port just flashes (about 0,5 s) immediately when pressing the power button. After that, nothing else happens.

I bought it from GearBest and sent an email to their support. Included pictures and a video clip of nothing happening. Got an answer where they asked to have pictures and video of the problem… Sent them again the pictures (via their support web page) and the video clip as email (as they ask if the size is >5 MB). They asked again to get the video clip… So I recompressed the video clip so it fits under 5 MB so I could upload it via the web page. Now waiting for their answer.

Video of the problem attached in case anyone has any idea of what to try next (in addition to trying to get some real answer from customer support…)

That sounds alot like what happens on the first startup after flashing the bios (takes long as its sorting out all the configurations). But after the first boot the others should turn the screen on almost instantly.

Gearbest is hopeless when it comes to customer service. watch what will happen, they will offer you “coins” as reimbursement! and you will have to fight them to be refunded. i hope you paid by paypal so you can use their buyer protection service.

Well, a week ago my Thinker completely died.

Same thing as you: Just a brief flash of the LED but no powering on.

So my husband said: I’ll try a solder reflow. He took the motherboard out, removed all plastic and rubbers, and put it in a pre-heated oven at 200C for 3 minutes. After that, he opened the oven door and let it cool.

He assembled it back and…. IT WORKS again! It also starts at once now, no more reboot the first time! 😀

Hey friends! I was waiting for my winter tires to be changed in Regina and saw a brochure for Fortis Gaintra Canada https://fortisgaintra.org/ in the waiting room. I was bored, so I signed up on my phone. I’ve been looking for a way to grow my savings faster than the bank allows. The trading bot here is excellent. It’s generated steady returns, helping me pay for the car maintenance and a bit more.
