If your laptop won't turn on, you could have any number of problems. The problem might be a genuine power issue derived from either battery failure or simply a loose AC adapter. Conversely, it may only appear to be a power failure, and the problem may lie with another component. Errors in brightness settings and LCD display malfunctions can both make a laptop appear to be powered off, and all these problems will need to be corrected. Look at the battery indicator light on your computer. Is it on? If so, check your brightness settings. If your laptop appears that it is not on, it may in actuality have lowered brightness settings. If the brightness setting is at its lowest setting, the laptop screen will be completely dark, and the laptop will appear to be powered off, even though it is not. Try cranking up the brightness settings. Check your AC power adapter. Is it snugly plugged into the wall or surge protector? Make sure the connection is made and it is not loose. Also, try connecting the power adapter into a different wall outlet. Check the status of your laptop battery by considering how long you have had the same battery. Most modern batteries are only good for about 1,000 full charges. After that point, the battery can and eventually will greatly deteriorate. Replace your battery if necessary. Replace your battery by powering off your laptop and then flipping it over and locating the battery cover outline, which will be near the bottom back of your laptop. Remove any screws with a Phillips screwdriver and pop off the battery cover. Slide out the old battery. Put in the new battery by sliding it in until it clicks, and then replace the cover. Consider replacing your laptop monitor. Your laptop may power on, but if the monitor display does not work, it will appear to be off and you will not be able to operate the machine. Check to see if your current LCD display works by plugging your laptop up to an external monitor using a VGA cable. If the external monitor displays your computer contents, your computer motherboard and underlying systems are still working, but your display will need to be replaced. Replace an LCD display by removing the screws around the bezel of your current display with a Phillips screwdriver. Pop off the bezel carefully and remove it. Then, locate the screws on the two metal brackets beneath the bezel and on either side of the display, and remove these too. Disconnect the inverter cable, which is plugged into the inverter. The inverter is located just beneath the display, at the bottom-center of the laptop. Then, pull back and slide out the old display, and replace it with the new. Put the metal bracket screws back in place, reconnect the inverter cable, and then pop the bezel in place. Replace the bezel screws. Hope this helps.

My battery light has been coming on and off for a couple of weeks now and saying "Service Battery Charging System".


Have your charging system tested. The battery light is turned on when there is a charging system problem causing an over/under charge condition. You may possibly have an alternator problem. If the battery is not being charged properly, the computer will start shutting down electrical components for protection and to keep enough voltage supply to enable the vehicle to continue running

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

2012 Grand Caravan. How do I turn the battery light off after installing a new battery?


Test the alternator. The battery light is for the charging system. Once the charging system is working with the engine running, the light should go off. If your light stays on with engine running, the alternator may need service or replacement.

To test the charging system, just put a voltmeter on the battery with engine running. The voltmeter should register at least 13.5 volts- alternator is charging. If you only show battery voltage with engine running, like 12.2-12.8 volts, the alternator or charging system is not working. The battery light should be on to signify this.

I have no power charged battery was ok before now no power check the fuses there ok can you tell me why i have no power please


it seems that the battery is not charged or not connected. When you open any door the light inside must turn on. When not, the battery is not charged. Charge the battery and try again.
When the battery goes again out of the power, it indicate that the charging system or alternator are not working properly.
Start your vehicle turn the headlamps on and check the voltage on battery. It must be higher than the voltage when engine is off.
If the voltage with engine on is about 14,5 V charging and alternator are ok. Maybe the battery is dead.
When the voltage with engine on is higher than with engine off but not 14,5 V, there is problem with charging system. When the volage is the same, it can be alternator or charging system.

Battery keeps going flat on gilera runner 125vx 4stroke


Three possible issues: Bad battery won't hold a charge or rapidly loses a charge. Bad charging system/ alternator. Current draw on the battery when turned off. Use a multimeter to check voltage on battery terminals when it is running. You should see at least 13 volts. Fully charge the battery for about 6 hours, unplug it from the charging system, and then check the battery voltage. It should be at least 12.0 volts, actually a bit higher. If your ammeter can handle it, you could test for current when it is turned off. You want the reading to be 0 or very close to zero,

Why doesn't it charge at idle?


It depends if the system is RVC/regulated voltage control. If so, there are about six modes of operation. One is, "fuel economy mode". In that mode, the targeted generator out-put is 13 volts and battery state of charge is greater than 80%. There are two other conditions.
Is there a battery discharge problem? Does the instrument cluster give charging system message or warning lamp?
Any charging system trouble codes? My info on your charging system is limited.

My dell inspiron 1501 will charge the battery but as soon as i unplug the laptop turns off.


It's either the battery or charging circuit on the system board. If you have replaced the battery with a new one then it's probably the system board. A new system board could run between $150 to $300. Then there's the coat of labor.
