Winbook TW700 is not turning on at all

my Tablet was working fine by several days but today is not turning on. I requested support via chat and after some tests, they suggested me bring it to a store for replacement. but now I am outside USA, so I decided open it with my nails it the borders (very easy to open) then I removed the battery and after 1 minute I reconnect it and now it is working fine again.
I write this in case anyone else has a similar problem. :)

You probably did a "reset" by disconnecting the battery. On the TW100 there is a reset "button" that you activate using a pin or un-bent paper clip. My wife's TW100 sometimes won't turn on and that "fixes" the problem. I have not had the same problem with mine.

Took me a bit to figure out where to start with trying to open the case, but this worked for me as well.

I used my fingernail along the long edge of the tablet. There is a very thin line that separates the front and back of the case (for reference, the power / volume buttons are part of the front of the case, the rear is on the other side of the thin line); by running your nail down the middle of the edge and applying some pressure you should be able to feel a space between some clips. Insert your nail carefully and then slide it in either direction and you should be able to get the clips to pop. Work your way along the entire side you started on, along the bottom of the tablet, and then up the other long side leaving the top for last. Once the two sides and bottom are released, open the back cover using the top like a hinge and swing the back cover away from the usb/audio ports.

You will see a thin foil like heat sink and the battery is underneath. You don't need to pull the battery itself out, just disconnect it from the main board. There is a single connector with 5 wires along one side with a couple of red / white / and black wires. Just gently pull up on that connection and it should release without too much effort. Wait a minute, re-seat the connection, and hopefully your tablet will come back to life (mine did). You can test the power button to see if it comes to life while the back is still open but I HIGHLY recommend AGAINST that for fear something else could drop into it and short something out.

Reattach the back cover by fit-ting (for some reason the MC forum sees "f i t t i n g" as a dirty "w o r d" (really, "w o r d" gets replaced too?)) the back panel over the ports on the top of the tablet first, close it like a hinge, make sure it is fairly well lined up, and gently squeeze the cover back together.

Thank you guys so much for posting this. This is the only place on the web that has any info about opening the TW700...I just opened mine because I was getting a black screen and couldnt boot. I unplugged the battery and the LCD ribbon and now my tablet is in working order.

Thanks!

This is super helpful! Had the same issue, but did not open the tablet. Basically, the tablet was sitting uncharged for a couple of days, and then it started right back up! The battery was fully discharged. I may have installed some software that may have freezed up the tablet. I think they should include this troubleshooting in the manual in case anyone else has the same issue.

Ref comments by CalBear on reset switch on TW100

I just posted a request for where that switch was, and exactly what it did. Only response was one that said I was wrong, there was no such switch.

I think its the small hole on top next to the Volume Controls (to put a paper clip in). Is this right? ... and what other than resetting battery(?) do you think it does?

Please answer here or in that post directly on the Reset subject. Thanks, Ev Merritt

I always thought that was a microphone. Do we not have a microphone? I don't see any other holes other than the speaker ones on the back.

Ref: othercents

Its TINY. Only big enough for a paper clip. That's why I thought it might be a reset "button". That's what some other electronic devices have. Mine has a real mic socket on right edge below SD card slot.

Greetings,

My USB connector had a contact pealed back inside the connector housing. It needs a new USB connector. I am now off to find a proper replacement.

Since my TW700 won't turn on now either. I figured I would open it up and disconnect/connect the battery. After opening the case, I was looking around with an eye loop and saw that one of the contacts in the USB connector (power in) was peeled back. Now I know why it wasn't turning on. The battery would charge for a bit then it would loose connection and never really charge the battery.

Best regards,
Fred
