Halo Bolt 57720 is blinking after 8 hours on charge and not fully charge as yet

I would check the key switch. On some models the ammeter carries the charging wire. Look at the back side of the keyswitch and get a plastic bristled brush and brush the oil/dirt away. . Plastic bristles are very important. Blow the back of the keyswitch and ir's connector off/out. The oil/dirt makes connections fail and short out the switch terminals

you should contact with the seller, or you need buy a new one, Games Gold, Games Items and CD Keys are available on https://www.m8x.com

on the charger there is a red LED that blinks while it is charging when it is fully charged it will not blink usually about 1 hour to charge a DeWalt 18v battery

I opened mine into the on position and the charge light went from blinking to solid red.

On an Archos, battery is fully charge when the CHG LED light is flashing, while that light is ON all the time, the unit is still charging.

Now, in order to charge your Archos you must leave it on Suspended mode, by holding the Power button for about 4-5 seconds until it says "Suspending", DO NOT leave it on completely "Shutdown" mode, or your battery will never charge, and you are also risking the life of your battery by doing so.

So in other words:

1) On a PC via USB it should take around 8 hours to charge, while connected to an Archos mini dock, battery dock, or DVR Station, it should take around 3 hours to fully charge.

2) Leave your unit completely "Shutdown" (hold the Power button and wait 10 secs. or so until it says "Shutting down" and let it go off.

3) Connect it to your power source, either USB on computer, or external charging device as mentioned above, it will come back on, the two LED lights CHG and Power will come on, leave it like that, and after a few minutes the unit will go into Standby/Suspended mode by itself, and there is when you are charging your battery the right way.

3) Wait 8 hours if connected to your PC, or 3 hours if connected to an external power supply (as described above). If still after being in suspended mode (not completely off) your CHG light isn't blinking after the 8 hours on PC, 3 hours on external power supply, then suspect your battery is defective.

In that case, if the unit is still under warranty contact Archos, if it is out of warranty. If it isn't under warranty, you can buy a replacement battery on eBay and either replace it yourself, or find someone with the technical skill to do it for you.

I hope this helped you.

Power green LED light should come on, CHG green LED light should also come on showing the battery is being charged. Leave your unit in Suspend mode while charging it, DO NOT turn it completely off as "Shutting Down.." because it will not charge your battery.

I just purchased an almost new Archos 5 on eBay recently, and the first day I had it, happened to me that I left the unit off and charging on the Mini Dock with external AC power supply, after 13-14 hours the CHG light still wasn't blinking. Then I though maybe I have to leave the unit in Suspend mode rather than completely off, which I did, and in a matter of 3 hours it fully charged the battery.

Again, do not shut down completely the unit, leave it on Suspended mode, or even on, and connected it to your mini dock, after a while the screen will go blank the unit will go into Suspended mode by itself, and after 3 hours on external power supply or 8 hours via USB on PC should be completely charged and your CHG light should be blinking, indicating the battery is charged.

I hope this helped.

battery may need replacing

Make sure the hold switch is not engaged - it will interfere with the charging process. Here is a link to the full user's manual:

the steady red light showing when in charger shows that
it is charging. the blinking red light when taken out of
charger or turned on and off means it is not fully charged.
leave it in charger till red light turns green.
