Hello , I have a navigator HK GPS-500WE who didn't power on at all. I don't know the history of it . First suspected to be a battery failure but it's good. I leave it to charge over 6 hours. When the battery is empty when i plugged into charger the lcd was illuminated a second white also when plugged into USB. When battery is charged this behaviour doesn't appear only if I push reset button. I can't put into boot mode because I don't know how , the computer doesn't recongnize at all.
Please welcome with any sugestions.
This behavior has happened with my 300. To fix it I will take it apart remove the battery connector for a minute then reconnect it put it back together and is was working until next time. This thing was happening on a regular basis but not very often. The battery looked good and I don't know what the problem is. I still suspect that is the battery but it is not worth to replace it. So from time to time I just open it do the battery connector stuff, put it back and go on. Hope this helps.
