My remote is red light is flashing. I changed the batter and the battery in the unit is working. I can turn on the fireplace manually


  • The usual indication for a flashing light is a low battery. Suggest checking the remote again. Especially for corrosion at the battery terminals.
  • When you operate the remote will the receiver flash its LED indicator confirming that the command has been received.
  • The manual operation of the receiver located at the fireplace likely does not require batteries. For remote control operation good batteries are required.
  • If the red LED on the receiver is flashing the batteries need to be replaced.
  • If the LED at the receiver indicated that the command is received check the wires to the control valve from the receiver. The voltage is a very very low a millivolt signal.

first check the battery or replace with new one. if the batteries are ok try to check the transmitter of your remote ( IR led) . you can check it by focusing camera or cellphone camera into the IR led of your remote then press any button on the remote if bright light shows your remote is working good. if no light you had to replace the IR led.marmeto12_0.jpgmarmeto12.jpg

2001 VW GOLF. battery draining over night, a friend of mine who's a mecanic put a light tester to the battery and checked all the fuses no leak there, disconnected the glove compart light switch...


Hi there?
You need to test the battery itself. It could be faulty battery. Some batteries have a little LED bult in them, green led good battery, amber led battery needs charging, red led battery needs replacing.
You could allways disconnect the battery after the use of the car. if the battery still goes flat then you need to replace that battery.

I have no led light on my e1705 when i press it and nothing comes on


Things to check:
1. AC adapter cord, esp close to the brick. Does the green light come on the brick? If not, replace the adapter.
2. Reseat battery. Check the battery charge by depressing the battery indicator button on the battery. Does it have a good charge? If so, then it could be the connection to the mother board causing the issue. If not, then replace the battery.
3. If both the battery is good and the AC adapter is good then you are looking at a mother board issue.

When you press the start button nothing happen not light or start up


First remove the battery and put it back in, you want to make sure it has a good connection.

Next you want to check the power adapter. If it has a built in LED light, it should turn green when plugged into the wall. If it does have a light and the light will not turn on or it blinks, replace the adapter. Next, plug the adapter into the computer, does the LED light change? Example, the LED light was a solid green, when you plug it into the computer it blinks. If the light does something along those lines, then there is a problem with the laptop itself.

If the power adapter does not have an LED light, then you need to use a Multimeter to check if the adapter outputs the right amount of power...which should be around 12 volts.

If the battery and power adapter pass the tests, then you are looking at a hardware issue in the laptop. From your description of the problem, I would guess the motherboard has died or that the charging jack on the motherboard came loose and needs to be replaced or re-soldered.

Two things that would stop the light from coming on, No Power or Motherboard is broken.

I have already changed the the power supply, but the computer don´t start no beep, only the the red led on the mother board light


The motherboards green LED light sends 5volt to the bios battery to keep it charged. It is normally called, standby LED.
Pull you're bios battery and check its current voltage. Use a volt meater. It should read 3 volt DC. See page 30 in you're manual. If you don't have you're manual you can download it from the link provided;
ftp://ftp.aopen.com/pub/manual/mb/ax4speun/ax4sgul-ol-e.pdf
You'll need Adobe reader installed to view the manual link. You're bios battery may need to be replaced. On the other hand the relay as shown on page 30 may be defective. If this is so, you will not be able recharge the bios battery. There is no fix for this other than replacing the motherboard.

Good luck!
Mike

Battery light 4 times is red and one time green in all the time


the battery LED is indicating an internal battery failure. While the battery may still work, the LED indication will not change until you replace the failing battery. It can be an indication of a Failed Cell, low voltage etc. Something in the battery is no longer meeting specification and that triggers the LED indication.

Remote control won't work. Have put in new batteries.


We have to CHK to see if the remote is functioning, Do u have a camera phone, if so look to see if the Infra red beam is flashing when you press the button, through the camera you should see a light if the remote is working. If not CHK infra red LED if read open change it. IF light flashes continuously change transistor. If the LED dont light but the LED is good CHK the XTAL.... Another way to check beam is a little transistor radio with the am band press remote while tuning until you hear a beeping sound. If the remote is working the sensor on the player itself is bad and need to be replace.......
