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.
The engine will have a generator under the flywheel, this should charge the battery when the engine is running, you can use a negative shunt on the battary terminal to check what if any power is going to the battery from the engine.
If the rechargeable battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.
When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.

Your battery is probably shot. The batteries for the Worx trimmers are terrible. They sell replacement batteries on ebay, but if you can afford it i highly recommend buying a quality trimmer from your local hardware store, either plug in or gas.
Green is charged, Orange is Charging and Red indicates a low charge or a possible weak or defective battery. All modern batteries are controlled by a microprocessor that monitors the health of the cells. Even if the battery is holding a workable charge, it can still be deemed "bad"
If the battery is fairly new you might get a replacement from Dell, if its a year or more old, it could be dying an early but not abnormal death. If more than 1.5 years old, be sure to check the Dell battery recall list as some of these are recalled and you'll get a free battery replacement if its on the list!
Charging LED Red LED is on = Being charged Red LED is blinking = Charging error Green LED is on = Charging is complete
● If the charge indicator blinks as red, it indicates a battery charging error. - The battery is not properly inserted - The terminals of battery are dirty or damaged If the battery is inserted properly and the charge indicator continues to blink, contact the nearest Samsung Camera Service Center.
If the charging LED doesn't turn to green could mean a signal that the battery is bad or can't charge 100% anymore = too old, needs a new battery. Hope this helps.
