First make sure you have the power wire connected into the post on your fuse box in the motor compartment,then check both fuses(green 30 amps) to make sure they are good.Older vehicles need to have the power wire connected.Newer vehicles will already have them connected into the fuse box.
Becasue the battery stores electrical power. You may get a shock from the battery if you short circuit it, or accidentally turn the laptop on while checking the power adapter. Alternatively, if you are checking to see if the power adapter is working, you will not be able to tell if the battery is in because it will be providing the power.
Probably the battery is discharged. It's possible the battery is not charging because the power adapter is dead. Check the power adapter with a voltmeter.
Yes! you need to use a power adapter as well a plug adapter in Egypt from the UK.
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter. Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.
A power adapter (sometimes also referred to as a power supply) is used to supply power to a range of devices. The power is taking from the mains electricity and transferred using the adapter to the device, such as a laptop.
12v 1.5amp power adapter is 18 Watt, can't load more than 18W power consumption,3amp power adapter can load 36W.
Yes, the power adapter is compatible with the Kindle
Most electronic equipment runs on DC (direct current), while the power supplied at receptacles is AC (alternating current). Some electronic equipment contains a power supply internally that converts AC to the required DC. Other equipment requires an external adapter to convert. When looking at an adapter it is important to get one that is compatible with the requirements of the equipment. The wrong adapter can damage equipment, or overheat. An adapter should be labeled with the following information. 1. check that the adapter input voltage matches your local power (i.e. 110-125VAC in US) 2. check that the adapter output voltage matches the equipment to be powered. 3. be sure the adapter output voltage is DC if the equipment requires DC--some adapters produce AC. 4. check that the adapter can supply at least as much current as the equipment requires. If it can supply more, that is fine. This will be in amps or more typically milliamps (mA) (for example it will say "200mA") 5. check that the connector on the adapter matches the input to the equipment-can it be plugged in? 6. important--even if the connectors mate, check that the polarity is the same. Unfortunately some commonly used power plugs are found wired both ways. For example, on round power connectors, sometimes the center is positive, sometimes it is negative.
You would overload and damage the device and/or the adapter.
You may have blown the circuit. Does the circuit work before you connect the adapter? If so perhaps the adapter is faulty.
Ac adapter (uses regular household power, DC adapter (car adapter), and battery pack
Every laptop is different. If you unplug your AC power adapter from the laptop and it start it up, then your battery is doing the work. If you want to check the opposite, remove the battery and make sure the AC power adapter is plugged in properly and start it up. If your laptop starts up from one form of power but not the other, either your connection is bad or the hardware itself (ex. battery or AC power adapter) is faulty.
