The battery was so discharged that it was too low to turn the system on. Leaving it plugged in and plugging it in and out 10 times just cumulatively added up to enough charge time to exceed the 3.2V threshold the PMIC needs to leave the pre-charge state. This confirms it here which is nice...

Hmmn, and did these returns start shortly after that overclock/overvolting app showed up? ;)

Some keymats shipped with this white powdery substance on the bottom of them. I don't know what it is but usually it was just around the rubber and not on the carbon pads and it was never very much. I would wipe it away whenever I noticed it. Perhaps a dusting of this stuff has gotten down to...

It shouldn't be like that. There's a strategy that I use to put the battery in to make sure it is as well lined up as possible. Stick the battery into the door facing the right way and then lower it into the compartment without letting it fall out of the door. The batteries themselves have...

That's a good point. I think I wrote a little quicker than I thought the problem through. I could see it going down one percent during the load time but several percent seems like a lot. I can look into the programming of the gauge and thankfully it is something any customer can update if I...

The reserve is not going to be much if you set it to shut down at 0%. I believe the current setting is 3%. Your gauge shows a battery life representative of what it is doing at the moment. Booting the board takes a fair bit of current since lots of stuff is running and the gauge will show a...

The actual algorithms for calibrating and reading the nubs is proprietary. They sent me an object file for that and an open source project package for the rest. The HAL, power management and I2C communication stuff is open source since it is basically all pulled right out of Atmel's free...

I just want to comment that 10 minutes wasn't a rule. Sometimes it could be 20 minutes, sometimes 30+ minutes. It depends on each individual battery and how long it takes them to pop back up from the fully discharged state to the minimum level the power management chips decides is enough to...

I'll just add one more reply to your questions naples. You will never, ever get the system to run on USB only. The power chip is designed to ignore USB charging if a battery is not detected. USB isn't designed to ever be sure it can provide enough power to keep the system up under any...

No, that's it. There's no extra glue. The speakers have an adhesive ring around the edge to keep them in the lid front when putting it together too. The real problem is that the lid front was designed with a bazillion clips that hold it into the back and we can't pull it apart without...

The battery doesn't catch fire, it just gets charged with a 0.5C load which didn't change the temperature of the battery but since it is not controlled, it could be an issue potentially. I think some people are still missing the fact that running without a battery is an UNOFFICIAL feature. The...

When no battery is found on AC adapter insertion, the unit goes into constant voltage mode which provides a constant 4.0V on the battery net. It doesn't like it if you put a battery in at this point because the TI chip doesn't appear to be designed to jump back to normal mode without a power...

Every board is completely tested and given a 24-48 hour burn in test before being shipped to Craig. It's part of the reason why they aren't making them as fast as they first promised. They are trying to help us guarantee a 100% success rate other than damage that could happen in shipping or...

Ah, a short film. <rimshot> ;) That video was hilarious!

That's not what I meant. It panics because it is running on newer hardware and it is the old, very first kernel to ever touch Pandora. It was the only one to ever have voltage control. It requires the code to be modified to match newer board revisions and I don't know where to look and didn't...

Well if the flash updater setup for customers fails (battery drain, act of God, accidental reset), then you will just have to do the flash update again as it will tell you it failed and fall back to the uboot menu. If the bootloader gets wiped, then you will have to do it like we do in...

The boards are flashed via SD cards with a bootable image that does everything automatically. It calculates check sums, flashes all the NAND partitions with kernels and uboots and file systems (DJ built in extra redundancy for future wear where some blocks might give out). It even flashes the...

Actually, it's the other way around. Rev1's were the slowest technically. It had nothing to do with the PCB, but the newer batch of chips that went on rev2 and beyond. Rev1 did 625MHz at OPP3 before losing stability (well crashed at 650 for sure). They did 900MHz at OPP5. Rev2 and later do...

Not too far off from the real conversations there Wootson. :(

There aren't. It's too risky for any mainstream company and the Chinese clones are cheap and underpowered so that doesn't count either. People who think something better is right around the corner and will be just like this are completely kidding themselves and I'm sick of reading it. The...
