Why won't it turn on?

did You find a fix? i just recieved mine and updated the firmware...now it wont turn on.

I fixed mine. Hope this helps. https://www.reddit.com/r/OP1users/commen...

I'm not sure if others have had exactly the same problem but this has happened a couple of times now with mine. I suspect that not using for varying periods perhaps corrupts some sort of EEPROM and/or whatever media the os is stored on. In any case, the solution seems to be to charge the unit for a couple of days ( even though it appears foobared ) and then attach the usb cable to a computer. Turn on the OP1 while holding the com button ( second down from the top rhs ) and you should then find the OP1 entering a bios screen. From here you can select an option to flash the firmware. You can download the latest firmware from the TE website and follow the instructions on the OP1 screen to do the firmware upgrade.

I'm pretty sure this second time with mine I already had the latest firmware so it isn't a matter of just upgrading the os, it's reflashing/formatting/writing it completely.

There was a useful Redit thread about this too, as mentioned by Justin above.

It's a pretty nerve wracking experience having this happen, but there is every hope this will bring it back to life.

I have to flash my firmware every couple weeks now because it won't turn on normally and the far right key is glitchy. very frustrating anyone know where to get this serviced in Seattle?

I will have to try some of these tips too, my op1 has been laying around for three years now. I can get it to run the Diagnostics and test which all run ok but it just won’t power up or allow me to do anything else. I too sent numerous mails to no avail. Just received the same same RMA request form mail for a Repair up north somewhere. Kinda gave up on it all together.

Most expensive paperweight ever.

Replacing the connector port fixed my issues:

After 6 years or so, my OP-1 pretty much required to be plugged in to work.

Then one day it stopped turning on all together. I was bummed.

It started acting strange over the last year - randomly turning on while the power switch was turned to the off position. Sometimes it wouldn’t turn on, other times it would.

I figured it was the battery but reading a couple other posts led me to believe it was the connector board. Totally worth the ~80$ to get it and it was super easy to install.

The microphone went out after a few years too, and since thats part of the connector board - it was fixed as well! Hurray!

This is for everyone who has had this problem….. I had this problem. For about 4 months I was confused as !&&*.

One day I decided I would bite the bullet and take a look inside. All that had happened is the flex connector had come loose inside the device, probably when I pulled out the usb. I clicked it back in place it worked.

Take a look at this link at how to access it.
