The battery light on my Samsung laptop blinking orange. Is it dangerous? What can I do?

On my Toshiba, blinking orange means the battery is charging up. When fully charged it turns steady green. If your battery is worn out, it will continue to blink orange.

As Larry says, all questions here need full make and model to assist you better, and Larry like the service tag number from the bottom as well. Larry (Anonymous) is our top Expert on Computers.

Goes through charging process Red light blinks then green light blinks like it is charging then after a few seconds solid green as if fully charged but it is still dead

I had the same problem. Your battery sounds like it got drained too much. The voltage on the battery is too low for the charger to charge. I looked on YouTube (how to charge battery that won't charge). I actually tried this today. I had a battery attached to one of those flashlights from a combo pack and the battery was drained down to 0.64v. The video I watched said take a higher voltage batter and boost it. Like a 20v to boost your 18v. Attach wires from one to the other. + to + and - to - I didn't have any. So what I did was stick 9v batteries together + to - in series I had 5 laying around. I taped a wire to the exposed terminals on the two end batteries and tapped the wire on the battery, which only brought it up to about 2.3volts. Then I just held the two wire on the battery for about a minute. It went up to about 6.3 volts I plugged it in the charger and it finally started charging. I don't know how well it will keep a charge. The batter is 10 or 12 years old. Hope this helps. And check YouTube. There is a lot of videos there.

Could be.Those batteries leak charge even when not in use.I would let it go for 24-48 hours just to be sure.Unless the batteries or charger becomes very hot.

What are the three wires on the back of the alternator for and what color does what o2 ford escape

It depends on which system you have. In both cases, there is a black and yellow wire that goes to the fuse box and a 15 amp fuse. This wire provides stator current to run the alternator. There is also a yellow and white wire that goes to the fuse box that provides the charge current to the battery. Now depending on the system, there may be only one additional wire (light green/red) to the instrument panel battery light or there are 2 wires (brown/white and grey/orange) that go to the PCM. In the latter case, the PCM monitors the charge current and then turns on the instrument panel light when the charge current is insufficient. In the former case, the alternator has circuitry to determine when the batter light should turn on. OK? Is there a problem we can help you with?

My Sony Vaio battery light remains orange

If the laptop 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.

Seems to charge but then wont come on

Sounds like you bought a defective battery
You can test for this by removing the battery and holding the power button for 15 seconds. This will restart the charging cycle as if the battery were new. If it still goes red get a refund and a new one.

Dell 9400 wont show AC power icon

If the computer is connected to an electrical outlet, the about10.jpg light operates as follows:
  • Solid green: The battery is charging.

  • Flashing green: The battery is almost fully charged.

If the computer is running on a battery, the about41.jpg light operates as follows:
  • Off: The battery is adequately charged (or the computer is turned off).

  • Flashing orange: The battery charge is low.

  • Solid orange: The battery charge is critically low.
Looks like the AC adaptor is faulty.
