Disconnect battery terminal and check charging voltage it should be 13.8volt per 12v if not present then check transformer, diodes, ic 317if faulty replace it

Why red charge light keeps blinking?


Is your battery a LiPo (Lithium?) If so ... These special batteries are charged by a computer circuit that holds the charge amperage constant and adjust upward the charging voltage until the required battery voltage is reached. At this time the charger hold a constant voltage and decreases the amperage as the battery capacity is "topped off". the charger circuit charges the entire battery at once but monitors each cell (cells are about 3.7 volts each) and controls the charge so that all the cells are ballanced.

When one of the cells that makes up the battery starts to go bad, the ballance circuitry prevents over charging the others, so one weak cell hold all the cells back from full charge and better charger circuits will signal you with an led or such that the battery is' going' bad.

Will not charge


This could point to several causes:

1) Accidentally disconnected battery or batteries inside Neato
2) A charger that is not properly assembled (check charging block connections)
3) A dead battery
4) A defective charger
5) Defective charging circuitry on the Neato motherboard

The easiest way to determine the actual cause is to thoroughly research each potential cause on the Neato Robotics forum, found here:

Camera will not turn on


I have had the same problem. Can be of two things.
1) Issue with the charging circuit. When you plug your charger on it should indicate a yellow light. If not, either your charger is not working or your charging circuit is not working. Go to the store and get them checked.
2) Issue with the battery contacts. Simply take out the battery and get a cotton bud and clean the battery contact both on the battery and inside the battery compartment.
3)Issue with the charging circuit and the internal circuitry. You will have to take it to the KoDAK store. I would recommend buying a new one.

I have a coolpix S2550 and i lost the charger for it so the battery was/is completely drained, i have recently found the charger, but now when i turn the camera on it comes up with a white screen and says...


Rechargeable batteries don't like being left in a discharged state for very long and are soon damaged.

If the battery is healthy but discharged it might be demanding more current than the charger and internal circuitry can provide causing the charging process to shut down.

The battery might be so discharged it is effectively open circuit and practically useless though sometimes it is possible to force them to take a charge by applying a much higher voltage (I use a car battery) to the terminals for maybe 2 or 3 seconds. It is a kill or cure thing...

My dell studio 1737 will not charge the battery; however it will run on either the battery or the power supply at leas until the battery dies completely. The power supply is working properly. I have tested...


If the power supply is powering the system without the battery installed, and the battery powers the system without the power supply attached, but the power supply will not charge the battery in the system...chances are very high the charging circuit on the systemboard is not functional. There are a few possibilities as to why but the only real solution would be to replace the systemboard since the charging circuit is integrated. You could run through the charging circuit to locate the exact fault but you will need schematics in order to resolve if you are comfortable with micro-soldering.

To verify, if you can, place the AC adapter and battery into another 1737 and see if you get charging on the battery.

On an E 100 Razor scooter, the battery charger shows charged


We had the same problem that I found to have a very simple fix. It seems all that needed to be done was hold in the reset button a few seconds while the battery charger was plugged in and the light on the charger turned to red and the battery charged again. Seems like too easy of a fix but it worked for my kids scooter.

Rechargeable Battery won't charge


I think this is a general Fuji design fault in the camera circuitry. I have an older F455 which has exactly the same problem and I did the same - bought new batteries only to discover that didn't help. The only solution is to spend even more money for a stand alone battery charger.
