Karoo 2 Won't Turn On
Answered
I've used my Karoo 2 a handful of times. Today I've tried to turn it on and it's completely blank, no sign of life. I have changed charger and cable and same issue. I tried a hard reset and the Hammerhead logo screen pops up for about a quarter of a second and then disappears. Advice please?

Hey Patrick,
Could you confirm if you were using a charger that supplies 5V at 2.5A? I would like you to also try to perform a hard reset on the Karoo : Hard reset
If the above issue still persists, please do drop us a mail at support@hammerhead.io and we will ensure to resolve this :)

Hi Hammerhead -- I have a Karoo2 and am a newbie user having done perhaps 4 or 5 rides with it. The unit has now gone dead, no signs of life. I have charged it using a brick and also directly into USB port, still no dice when I press and hold the B button. Guidance appreciated. Thank you.

Hi, this has happened to my brand new Karoo 2. Used it on a few rides while the battery lasted from initial set-up and charge. Went to recharge it using the provided Karoo 2 charging cable, plugged into my laptop. It then did not turn on and was completely unresponsive. Factory reset, which rebooted it, and had to go through the entire set-up process again. Tried to charge it again as it was still low and the same thing happened. Now it shows a 0% battery screen sporadically but is still not working and is completely unresponsive.
Have a support ticket in for +24 hrs but still no response. Please help.

I'm sure support will be back with you soon. Try the supplied cable together with a good quality wall adapter like for an iPad and leave it charging for a few hours. Karoo 2 seems picky about charging source and does not like fast chargers. Since I started to use the supplied cable with an iPad adapter everything has been good. Not an ideal scenario.

Thanks for the reply and tip, Rob. I have just plugged it into a wall adapter with their cable. Going to leave it a few hours like you suggest. Perhaps it didn't like being charged from my laptop (?). Although it worked fine being charged the first time straight out the box.
It's a shame because it's an excellent product when it works.

Hi, same problem. I have had my Karro 2 for quite a while, but I though Hammerhead would be able to solve this through updates.
My Karro 2 have never been able to charge unless already powered on!
After the latest update 1.212.1045.12 this still persists. However yesterday the Karoo drained the battery completely in approx 3 hours. As it was not switched off, I could not charge it. Only solution - like many times before - is a hard reset, which requires an effort with restoring settings.
Add to the list of problems that the sensor connection is a as bad as EVER. It loses and reconnects sensors like all the time! -
Hi Hammerhead -- I have a Karoo2 and am a new-ish to using it and have done perhaps 4 or 5 rides with it. The unit has now gone dead, no signs of life. I have tried charging it directly into USB port, but still no dice when I press and hold the B button. Guidance appreciated. Thank you.

I have this problem too and would like to have clear guidance on both the causes, problem and resolution.
- What are different scenarios and recommendations around various types of charging? (This is important when out on the road and charging options are limited)
- How exactly is "fast charging" causing the problem?
- What is causing the brick mode? Is it completely our of power or has it crashed/frozen? (The troubleshooting steps are very different with or without power)

I have also had this problem. I've only used my Karoo 2 a few times, but it seems incredibly fickle about whether it will charge or not. I found it wouldn't charge from a USB port at the back of my desktop computer... so I tried a plug into the wall with a USB socket. That worked. Then tried to charge it up at the wall again after a ride, and when I came to switch it on, there was zero charge, it wouldn't power up. I had done the latest software update in the meantime... has that affected things? So I then tried my desktop computer again... and it seems to be charging.
This really isn't acceptable, can Hammerhead please explain what is going on, if they have identified a problem and fixed it in the latest software (e.g. so that it only charges from a low power computer?) then please tell us!

Try the supplied cable together with a good quality wall adapter like for an iPad and leave it charging for a few hours. Doing a hard reset usually solves this after is charged. Karoo 2 seems picky about charging source and does not like fast chargers. Since I started to use the supplied cable with an iPad adapter everything has been good; never had the issue again.

Hammerhead support: can you please respond on this question of what charger output should be.Looking at the range of Apple chargers, you can see that there are 4 different types for different iPads..

So the information 'an iPad charger' doesn't really help....

I don't work for Hammerhead, just trying to help a bit. Try looking here...

Hi Rob
Thanks for all your help. I worked out that you were a super-helpful user, rather than Hammerhead. Thanks for the link, not sure why I couldn't find this myself... Now I just have to work out what volts/amps different plugs and computers are outputting...
Cheers and thanks again
Peter
