My new 3590 turns off automatically after a few minutes while connected to my PC. The time before shutdown varies. It can be anywhere from 1 minute to 8 or 10 minutes. It doesn't matter how I connect it with the USB cable. I've tried it with the unit on and with it off.
I'm trying to download a full backup of the unit, but it never gets very far into the procedure before it shuts down. The battery is fully charged. It has never shut off by itself when being used away from the PC, either handheld or in the car.
Any suggestions? Or do you think it might be a lemon that needs to go back to the store for a swap?
Thanks for your help.
My first thought is a defective cable issue. Do you have another cable you could try?
Or try a different USB port, one that is wired directly to the motherbaord and not a hub.
After having tried both previous suggestions and if your still having the same issue I would try the following.
I have Windows XP and the computer will shut the usb ports with time to save power. To avoid this
1-Right click on my computer
4-Click device manager
5-Click + next to universal serial bus
6-Double click usb root hub
7-Click on power management
8-UNCHECK setting that allows computer to turn off device to save power
9-Click ok and do the above for the other hubs.
I charged the 3590 overnight out in the car just to be sure the battery really was full, thinking maybe the on screen indicator was not telling me the truth (turned out it was). This morning I started doing a backup of all of the nuvi files. This lasted about 4 minutes and then the nuvi turned itself off again.
I then started trying out the suggestions you guys were kind enough to offer...
CraigW, I ran the job again using my backup cable, but it shut down just as before.
canuk, I then went into the Device Manager Power Management settings and turned off all of the Save Power options, but the results were the same when I ran the nuvi backup again.
muell9k, the next thing I did was what you suggested. IT WORKED!!! I don't know why (and that's the reason I saved it to the last) plugging the USB cable into a port on the front of my PC would do anything different than plugging into my desktop USB bus would, but it did.
Thank you, CraigW, canuk, and muell9k.
You guys are the best.
Glad it worked for you.
You are not the first person that had this issue and was caused by a USB hub.
Ruffrider and thanks for the feedback which will certainly help others who encounter similar problems down the road.
