Lately, I've noticed my N800 w/ OS2008 hanging. I've noticed today, that it seemed to be when it is connected to the internet. I've thought about doing a backup, and then reflashing the OS. Any other suggestions?

I've noticed after it hangs/reboots that the battery has gone down considerably. Is this from it getting the CPU locked up?

Also, I've dropped it recently, hard enough for the front cover to pop off. But besides some scratches, nothing seemed broken except that it seems slower.

Rebooting sucks a lot of battery.

I used to have the problem of my N800 randomly rebooting pretty often. I did 2 things, 1 or both of which helped quite a bit (not sure which did the trick since I did them at about the same time).

1. Try reseating your external memory card. Make sure it's ALL the way in. And that the door is completely closed.

2. If you are using your internal memory card as swap space, then try reformatting the internal memory card. Note that to have the N800 format it, it has to be mounted in the external slot at the time.

Hope these help. And yes, any time the device reboots, a huge chunk of battery life appears to be lost. Some of it "comes back" over time, but it seems that it really does drain some of the battery.

I tried the SD cards reformatting and making sure they are seated, but it did not fix. It will run fine until I connect via WiFI, then things slow to a crawl until the machine reboots. I want to do a reflash, but can't find the original Nokia cord.

Any USB data cable with the correct end will suffice. Or at least it did with mine.

I also found that I needed to pack the SD card in my internal slot with a piece of folded up paper. I think that it moved about fractionally when carrying it in my pockets, and momentarily broke contact, thus upsetting the virtual memory I had setup on the card.

How's your battery holding out?

When my battery started to go (consistently reported as full charge after charging, then it would drop to nothing within a few minutes after starting a new task) it would spontaneously reboot every 20 minutes or so when hooked to the charger.

If I opened an Internet connection to a page that updated frequently or ran the media player, the reboots would stop. All this made me think that the reboots perhaps were voltage related and may have been prompted by the system itself.

In any event, in my case this issue went away when I got a new battery.

'k, hangs and reboots - seen these...

What I have noticed is N800 if overly stressed (too many web pages); and subsequently tablet reboots, some strangeness can be seen with settings - eg bluetooth turning on, when previously set to off. Never been an issue - setting change is obvious and easily changed back...

The setting change that seemed to be cause of instability - tablet stopped asking for device lock code on booting - just booted straight in. Stability seems restored by changing device lock code in settings (no need to use new code - reentering current code sufficient). Tablet then begins requiring code on boot as expected.

Perhaps the lack of asking for code on boot would be obvious to everyone else - for some reason it took me a bit of time to notice change. Doh... Thankfully noticed before reflashing tablet - doesn't look like reinstall now needed.

When I updated my two devices to the latest firmware I got battery issues.

Did the new battery fix the problems?

Do you have swap enabled? Either in the OS manually or in the control panel using virtual memory?

Without some swap space reboots will happen from memory leaks more easily.
