Hello! It seems that you have a problem with the laptop charger connector. It maybe in short circuit. You can try to look for some electronic workshop that works with reballing, BGA solder, etc., that might change it. In Portugal we have some, so I think in other countries you can find them to.
Whenever you need to charge your power chair or scooter get into the habit of charging overnight. The battery level indicator lights will tell you if your chair or scooter needs charging. Whenever the lights are down into the yellow and especially if they are in the red. If you have the off-board charger, plug the charger into the charger port in the front of your joystick and then plug the charger into the wall socket or turn the on/off switch on and let it charge overnight. When you get up in the morning the charger should have a red light(power) and a green light illuminated (indicating fully charged) Always turn the charger off or unplug it from the wall socket before you unplug it from the chair or scooter. Never have the power on to the charger when you plug or unplug it from your chair or scooter. Whenever you get new batteries always give your batteries a full charge before use and then if you use the chair daily charge it every night. If you do not use your chair or scooter daily charge it at least once a week. Never leave the charger plugged in and on for more than 24 hours. Your batteries should last you 3-4 years if you charge them correctly.
If it does not work with the Charger while the battery is out then I would say either your charger is bad, the dc power jack where the charger plugs into the laptop is bad or you've got motherboard issues. Does the charger have a light on it to indicate that it is on when plugged in the wall? Do you see any lights when you plug the charger into the laptop?
Take an ink pen and see if the little pin inside the computer where the charger plugs is loose and moves a bit. If so that is probably your problem. If the pin is tight and the charger works, then you've got motherboard issues.
Janice check your charger it could not be charging the batteries. Now always charge your batteries overnight while you sleep When you get up lights on the charger should be red and green if they are red and yellow then the charger hasn't fully charged the batteries and overnight should be more than enough time to charge fully. This could indicate a bad battery remember new doesn't always mean good. Like they say always charge before use and this goes for new batteries too you need to charge new batteries nightly for 10-15 days before they start operating at 100%. If when you plug in the charger before bed and the lights are red and green then there is a problem with the charger or the batteries or the charger circuit Hope this helps you
Phil the red means battery is low and the green is a speed limit code because of the low battery if you have charged your batteries and you still get the red then you need to check the charger after charging all night does the yellow light on the charger turn green? if when you first plug in the charger if the red light is on and the other light is green then there is a problem with the wiring or connection to the batteries from the charger and you aren't charging the batteries. if when you plug the charger in and you get a red and yellow light then the charger is working but you don't ever ge a green light and the battery level gauge is still showing red then you need to replace the batteries Hope this helps
Carla Under the front bottom of the joystick you will see a charger port its a three pin port that accepts the plug from the charger. Always plug the charger into this port with the charger off or not plugged into the electircal socket. Then plug the charger into the electical socket or turn it on. You should see a red light and a yellow light on the charger. When the tellow light turns green the batteries are charged. You should get into the habit of charging the batteries each night if you use the chair daily. Just plug in the charger when you go to bed and turn it off when you get up. If you only use the chair a little then always store it fully charged and then charge it once a week if it hasn't been used. Hope this helps you
Eduardo After using your chair and the battery level lights are down with yellow or red lights showing just plug the chair into the wall socket and let er rip. Now really after using your chair during the day and you are ready for bed just plug in the charger and let it charge over night. In the morning unplug the charger and you should be set for the day. If you don't use the chair everyday always put it up with a full charge and about once a week plug it in and let it charge overnight. Never leave the chair plugged in all the time and never leave it for more that 24 hours. The charger has two lights on it one red and one yellow or green that are hard to see because they are under the rear cover. When the chair is fully charged the yellow light turns green and you can unplug the charger and you should have a full charge. Hope this helps you
I had the same problem and found a solution on another forum...
Plug the battery into the charger. The yellow and green lights come on. Leave the battery plugged into the charger. Plug and unplug the charger power cord from it's power source a few times until the the red charger light comes on..... problem solved!
I think the "smart" circuit in the charger that is supposed to trickle charge before the regular charge cycle needs at least some battery power to test and start the cycle. If the battery is totally discharged, the test can't deternine the battery status and will not charge.... Plugging and unplugging the charger seems to bypass this teat and charge the battery normally. The charging process should work normally after this method.
Probably the plug on the navman has suffered what we call dry solder joints from inserting and pulling out the charger you need a tech to fix it. soldering is nesessary shouldnt be too expensive I fixed mine its about half an hours work if not too damaged inside
