LED, Speakers, and Keyboard problems

Open the case and turn on. There should be a corresponding led lit inside. That, or you could run Insight Manager. It will tell you exact details.

Isnt your battery drain ?
Have the same behaviour on mine ... I can reflash the system with supply on , but it wont stay long before reboot ..

have you tried the soft reset yet?
take out the battery and let stand in freezer (put in plastic bag to keep out moisture) for 10 mins.
hold down the switch key wich is right above the escape key on the left side of the screen. and hold down the power button till she turns on. once you get the usb symbol in the upper right turn it back off and it should run like normal.

I hope you put the battery in properley or els you can go to this sight for anny help http://www.retrevo.com/support/Nokia-N810-Tablets-manual/id/4357ci062/t/2/

Hi,

Turn the keyboard upside down and look for a small button that will say "connect" next to it.
Also press the connect button on the receiver.
To activate the keyboard just hit the space bar. If your still having problems check the batteries.



Regards.

this site may help but you can ring up nokia phone nomber for the code http://www.retrevo.com/support/Nokia-N810-Tablets-manual/id/4357ci062/t/2/

chances are there have been short circuits on the keyboard controller. better bring it to a service center

Does the navman site say the software supports vista ? It may be trying to use the active sync that windows XP used... Check if their is a software update on the navman website.
