Unit does not boot up - Lowrance Elite-7 Hdi Sonar/Gps Combo, Model 83/200 Ducer

as sonn as you turn on your unit continuously press F12 before the windows logo shows. this will take you to bios where you can change boot options. Make your cd/dvd/ the first pop in disk save settings and exit unit will reboot then tell you to press a key to boot from disk you only have about 3 seconds before pc boots normally

It is not possible to boot.
The unit did not boot up properly

It can not be reset. The unit has to be flashed with a service firmware to access the units flash drive. Then the missing or corrupted files need to be replaced. This is why the unit is crashing on boot-up.

Once the files have been restored then the unit can be reflashed with the factory standard firmware.

The problem you have right now is that the unit can not be found by your PC because its in an endless loop-boot-up and never reaches the main screen to detect that it is connected to a PC.

Hi,

Unfortunately, there isn't an easy solution for the Nuvi owner as it requires a custom piece of firmware to flash the unit to make it at least boot. This problem is often caused during a failed firmware and/or map update.

It sounds like a file was corrupted. Sometimes it is better to connect the unit up to a PC, delete the old map and then proceed to install the new one. There are so many issues with memory space causing failed downloads and corrupted files.

If the map file is missing, the unit will boot-up OK, it will just say "Map data unavailable" but if the map file or associated map files are corrupted, it can cause the unit to crash. Your PC won't recognize the Nuvi because you have the reach the main screen before the data communication mode routines are accessed.

We've had some success in restoring some of these units by flashing a "fix" firmware in "pre-boot mode" that doesn't try to load the map or map associated files. This should then allow the unit to boot. Once the unit boots, Windows will recognize it and then you can copy a map over to it from the PC. Reboot the unit and then flash it with the standard firmware.

If its leaking from the boots then you need to replace the whole unit, the leak is internal, by replacing the boot you will just hide the problem and the fluid will leak inside the boot until it fills the boot and then when you turn the wheel the fluid will blow out the boot ends. hope this helps. good day.

shut down unit...pull power cord...pull the battery out of the unit ...reconnect power cord see if unit will start up... if it does, go to e-bay price a new battery... you have the information on battery...

shut down unit re-install battery see if it starts up...if it does unit was dropped but ok for now.

if unit does not start repeat first part,,,, order battery or bid on one or wait a while till you have the money.. or do battery pwr test...if not replace battery with a known good battery see if computor will boot if it does boot.... bad battery.

Unplug unit!!
Remove outer boot clamp by prying off at bottom. Peel boot back on right side. Remove screws holding latch assembly.
Reach through area exposed by peeling back boot and pull out lock assembly. Unplug unit and install new one. Reinstall boot.

If you have changed the power unit and the computer is still not powering up, then it is quite likely there is a motherboard fault - probably in the power management circuitry, which expects the power_good signal from the power unit at a precise moment in the boot up process. A fault in the power management circuitry would prevent the computer from beginning its boot-up process.

Do the fans in the power unit come on when the computer is switched on? If they don't - this suggests a power unit problem. If the power unit fans do start working but the computer still doesn't boot, this suggests either a faulty or 'dry' connection (easy checked) or a motherboard fault.

If your computer 'works' but nothing is displayed, try pressing Control+Alt+Delete. If it then boots up it suggests a power unit problem. If not .. we come back to the motherboard again.

A low wattage power unit can cause the problem you describe. Every 128 Mb of Ram needs 4 watts of power. Add more for the motherboard (up to 30 watts..) then the floppy/hard drive/dvd etc .. If the power unit can't supply the necessary wattage, it won't boot. The older 250-300 watt power units aren't suitable for modern computers with XP/Vista. Ideally, you should be looking at 400 watts plus -it will tell you on the power unit.

Though to be honest, it does sound like a motherboard fault.

The only other thing that can cause a computer not to boot up (though it will begin the boot up process) are other faults ... When you switch on does it actually display anything on the screen .. and are there any 'beeps'? 1 beep indicates everything is ok .. 3 short beeps and 1 long beep indicate a memory problem (and the computer won't boot..). 8 beeps indicate a video problem (and nothing will be dislayed on your screen). Same with 9 beeps .. which indicates a bios fault - and the computer won't continue the boot process.

If you have nothing .. no power whatsover ... it comes back to the power unit/mainboard. If you're happy that the new power unit you have put in is ok ... suspect the motherboard. If you have access to any unwanted or 2nd hand motherboard ... connect that. If your computer boots up ... its the original motherboard at fault.

Alternatively, rather than replace bits and pieces at random to cure the fault, take your computer along to a computer shop. It will take them minutes to test it for you and identify the fault.
