Issues

Device will not turn on

1.) Is it charged?

I know this sounds silly, but most modern devices require a lot of battery power, and if they are not charged well enough they may not even turn on. Just plugging it in may not help, because the wall charger doesn’t provide as much amperage as the battery.

So firstly make sure your device is properly charged. Plug it in for a minimum of two hours before trying to even power it on. Especially if it has been a few weeks since the last time you have used it.

2.) Are you using the correct charger?

Remember Modern devices require a lot of power, and not all USB power supplies are created equal. If you have misplaced or do not have your school issued charger, please check the wattage rating, voltage, and amperage output of your USB charger.
If it is capable of charging your USB device, it should run a minimum of 10watts; that’s 5.1 Volts (V) and 2 Amps (A) although some newer devices actually do require higher.
This however is a minimum requirement suggestion.
If the charger has Amps listed in milliamps (mA), know that it does not have enough power to charge your device.
Always use the proper charger for your device.

3.) Are Your Cables in optimal condition?

Is your cable frayed or are the contacts charred?
If so, acquire a replacement.

Device ‘not charging’

Check the light by the charging port.

If your  battery meter  indicates  no charge, not  charging, or  doesn't seem to have as much  life (percentage) as you think it should; but the charging light is lit up (red), then the laptop is charging. The issue is that the software just doesn’t know exactly where the battery stands… It has to take the voltage of the battery based on graphed information and then apply that to a human readable percentage. Therefore, if the computer has not been allowed to fully discharge recently, then the software does not know what the percentage is. The simplest way to solve this, is to allow the computer to use up all its battery power.
Then while it is off, fully charge the device.

  You can tell if your HP Stream is fully charged when the charging light changes from red to white [HP Stream G4,& G5].

If you plug in your HP Stream and the light does not come on, this could indicate one of two problems.


1.) Your charger is bad and needs to be replaced.

2.) Your motherboard has experienced a short and needs to be reset.

For either of these problems you will need to turn your laptop into the Kingsland tech department for repair/replacement.


As for the Dell Latitude 3120 its charging light is a bit more enigmatic... 

as it is white while charging and turns off when fully charged. The Dells only shows red for error states. I find this approach to be much less helpful overall.



If all else fails, please take your computer to the High School office,
turn it over to Brandy Lusk and fill out the paperwork.

In this way the Kingsland Technology Department can quickly obtain and repair your PC, with as little turnover as possible.
