810 keeps rebooting, wont go past white nokia screen
 

Ok guys, was just using my nokia last night. Went to turn it on today, and wham, cycles the white nokia splash screen, doesnt even go into the hands, just goes black and cycles again?

Any ideas?

How about...search the forum?

Hi There,
I have the same problem with my Nokia N810 keep re booting.
Any body have a fix, please share. Thanks.

The easiest and most common fix, I believe, is to reflash the tablet and start fresh.

It also does this if the battery is dead. buy a cheap battery charger or battery on ebay. here is a good deal for instance.

Agreed--if the battery is very low or damaged, it will boot for a moment and then immediately power-off to protect the battery.

If you HAVE plugged it in and left it charging for a few hours and it's STILL doing this, it could be that something corrupted the apps/data and ruined the boot process/drivers/etc. In that case, you will want to re-flash the N810 to get it back to a sane state.

The battery management system in N810 is also unable to safely charge very degraded (50 - 60% of original capacity remaining) batteries when supplied by the strong charger included with N810. A weaker charger would perhaps be able to charge a degraded battery, but the power consumption from rebooting would draw more power than is being put in, so it'd probably never reach net positive charge rate.

tl;dr: Yes, try a new battery

I've recently let the battery go down on my n810, it was sitting around for a month or two (I know, shame for neglecting the device). Of course, same issue -- white screen, reboot, white screen, etc.

My fix -- take out the 3.6 volt battery from my cell phone, hook wires to the battery terminals and jumper them to the n810 battery. Sort of like jump-starting it. Had to hold it in place for about 5 - 10 minutes till I had enough charge, put battery back in n810, which was just enough to get it to boot into the charging program. Now it is fully functional again. Whew.

Disclaimer: I am not recommending this to anyone, as charging a lithium battery from an unregulated source can be hazardous and may cause an explosion. In my case I was constantly monitoring both batteries temperature, but I could see the potential for a problem.

Oh, and for extra geek points, I didn't have any wire with me at the camper. Did have aluminum foil though, which made for some nice and dangerous uninsulated conductors. Sometimes I'm surprised I still have all 10 fingers.

Battery -
Look for my thread -
Got a good battery for $9 shipped.

I had the same problem, I tried with some different nokia chargers and N810 was always rebooting at the nokia white screen.

After that I decided to try with other chargers, and I used one from a Palm device 5,2V an 0.5A (I need to cut the wire and change the connector), and the N810 started to charge.

Conclusion: You can try with a bit more of voltage, maybe it isn't the perfect solution but it is a solution.

Re: 810 keeps rebooting, wont go past white nokia screen
 

Well there are 2 type of electric current... AC and DC
AC currents should be safe when touch as they would need a strong conductor and need a direct connection to their reversed side... + to - while direct currents should shock you as long as you have at least a conduction to it... Like power outlet to your homes and your grounded to the soil or any other conductive materials. :D

Re: 810 keeps rebooting, wont go past white nokia screen
 

That is probably one of the most misguided and unclear things I've read about electricity in a long time. AC doesn't need any stronger conductors than DC, if anything it's the opposite...

Both DC and AC need two conductors. The powergrid is grounded to the earth, so anything with a low resistance path to ground can serve as one conductor.

As for danger, it's all about current through your body, and that depends on the voltage. For a given voltage, AC is probably more dangerous. The battery's 3 - 4.2V poses no electrocution danger.

The danger in the above case of the battery is not that you'd electrocute yourself, the danger is when using uninsulated wires that you'll accidentally let them touch eachother, which will lead to a short circuit, which can make the battery explode.

As for dapenzerg the lower voltage of 5.2V (compared to Nokia chargers' 6V or so) and the lower current of 500mA is probably what helped. The reason it reboots with a crap battery is that the hardware can't regulate the charge current low enough, which results in overvoltage on the battery. which makes the charger software abort, which makes dsme reboot the device.

shadowjk my N800 and N810 old chargers were 5V, and I did the opposite to your method, that is I increased the voltage.

Re: 810 keeps rebooting, wont go past white nokia screen
 

A N810 will actually reject 5.00V. it accepts 4.2V - 4.8V and 5.2V - 10V or so, with varying current profiles (a 10V 1A charger is rejected but 10V 0.1A might be accepted).

The dc adapters are labeled 5V, but they actually give out somewhere between 5.2 and 8V. 5.8-6 is the most common I've seen.

Re: 810 keeps rebooting, wont go past white nokia screen
 

Good info, I will check my chargers with a voltimeter, because I was trusting in the labeled voltage.

How do you check the output voltage? when the charger is connected to the Nokia device?
