Your battery terminal (or battery post) can undergo corrosion from exposure to the leaking electrolyte solution, vented hydrogen, atmospheric moisture, and so on.Īdditionally, heat generated from your engine can accelerate the corrosion of your battery post or battery terminal.īut how does that affect your car battery?Ī corroded battery terminal or battery post is a poor conductor of electricity. When that occurs, your battery can’t be charged anymore with the broken alternator belt, and the battery warning light turns on. However, with repeated working, this alternator belt or serpentine belt can develop cracks over time and finally break. Run the air conditioning system, power steering, and other vehicle accessories.Spin the alternator which charges your car battery.Reason #3: Broken Alternator BeltĪn alternator belt (aka serpentine belt) uses the power generated by the engine crankshaft to:
And this can negatively affect the proper functioning of your vehicle battery.Īs a result, the battery warning light can turn on to indicate that you’ve got a failing alternator, or worse, a wholly damaged alternator. If your vehicle has a failing alternator (or faulty alternator), it’ll probably produce a voltage outside the optimal range. In many cars, the optimal charging voltage is between 13.6 and 14.6 Volts. If your vehicle’s alternator is malfunctioning, the vehicle battery may not receive sufficient voltage for proper charging, or it may get exposed to excessive voltage. Reason #2: Malfunctioning AlternatorĪn alternator is a component that charges your vehicle’s battery. When either of these happens, your dashboard battery light activates to warn you of a bad battery or dead battery. As a result, the battery voltage (and battery power) generated will decrease.Īnd with a dead battery, the battery voltage would just drop to zero.
#Car battery indicator light stays on plus software
Someone told me it sounded like it could be a software problem, but could it be a hardware problem? I hope someone can help me.maybe give me an estimate of how it'd be to fix it (generally).The battery warning light on your dashboard usually gets activated due to one or more of the following seven reasons: Reason #1: Bad BatteryĪ car’s battery usually lasts between 3 to 5 years.īut, as your car battery ages, the electrodes inside it might break, or the electrolyte contained within the car’s battery may leak. I'm also running Snow Leopard 10.6.8 if that helps. I highly doubt a water spill accident that happened a year or so ago would have anything to do with it now, but could it? Over a little more than a year ago, the laptop did suffer a water spill accident close to the left side with the ports but after it dried out it ran flawlessly since it had happened.like nothing had happened.I'm only having these problems now. Could a power outage have anything to do with it? As long as I can remember I've never had anything electronic suffer due to a power outage and everything still worked afterwards in the house. I can't remember for sure, but around when it started acting up like this I think we had a brief power outage in the house.
Could it still be a faulty battery problem?
I tend to keep it plugged in most of the time. The battery shows only 34 cycles and in "Normal" condition. Now when this happens I usually tap one of my keys instead and eventually I'd get it to where after I wake it up it will stay up and not shut off.Īs for the battery problem, I've tried another adapter and the problem still persists on my laptop so I don't think it's the adapter. I'd wiggle my mouse and it would wake up for a short period of time then go back to sleep mode and if I tried waking it up again it'd eventually do a quick shut off. I've tried SMC a few times and it didn't work.I even tried to reset the PRAM and if anything it just made my laptop worse.and it started having the new problem of falling into sleep mode whenever I'd be in the middle of using it. I had suspected that it recharged while it was sleeping. Then even later, it got to where I hardly see the orange light at all.and the percentage had been sitting at odd numbers (below 95%) but it was clearly discharging and recharging intermittently. Later I disconnected it and replugged and it would turn green to orange every few seconds. Around September I believe I started noticing the problem of my battery showing "Not Charging" on the indicator but the Magsafe adapter still showed a connection and was powering green.
