Flashing cf after carrier ac turns off

My ac turned off by itself and started flashing "CF" on the led display. No matter what buttons are presses on the AC or remote, the AC will not respond. I have to unplug it then plug it again for it to work again. What does the flashing CF mean?

On this air conditioner it's the "Clean Filter" reminder.

Once you've cleaned the filter, you can reset the reminder with the remote (look for a button or a 2nd F labelled Filter Reset).

Laptop hp cq62 not start, black screen. after pluging ac cord he start itself, and after that, it is impossible turn it of.


You can generally only flash a bios if you can get the machine to boot up into some operating system. Do you get ANY on-screen logos or messages when you apply power to the laptop? Can you get into the bios when you power up the laptop and press Esc (or F2 depending on your model)? Do you hear any sequence of 'beeps' when you power up the laptop? A series of short/long beeps when powering up indicates some kind of error detected by the Power On Self Test (POST) routine. Do you have the HP recovery CD for your laptop? Have you put it in your CD Rom drive and tried to boot up? Check the manual at HP Support for a hard reset procedure- you could have a bad power button board or other hardware problem-it is not usually a BIOS problem.

HP DV2036ea i have a blank screen on the computer


Hello there

Description.

When pressing the notebook power button nothing is displayed on the screen or display. The cause of this problem may be a failed AC adapter, the memory modules (RAM) need to be reseated or a failed notebook system board component which will require an HP certified repair.

Below steps will assist in identifying the cause of the problem and suggest the best solution. Test the AC adapter Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board.
  1. Remove the battery and disconnect all external devices from the computer.
  2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
  3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
  4. Press the Power button to start the notebook PC.
If the notebook does not start or the display is blank then check the power indicator light or power socket LED. Check the power indicator light or power socket LED On newer models of notebook PCs, there is an LED or indicator light around the power socket on the notebook. Check to see if this light is on or off, when the notebook is plugged into AC power.The power indicator light or power socket light should turn on when the AC adapter is connected.

  • If the light does not turn on then the problem is most likely related to the AC adapter or the electrical source in your home or office. Go to the Light does not turn on section on this page.
  • If the light does turn on but the notebook does not start or the there is a blank screen then continue to the Light does turn on but the notebook does not start section on this page

The light does not turn on when the AC adapter is connected If the power indicator LED is off, the AC power adapter may need to be replaced. To determine if the AC power adapter needs to be replaced follow the steps below:
  1. Ensure that the AC adapter is plugged directly into a known working wall outlet.
    NOTE: To check the wall outlet, plug in a different known working device like a light, radio etc.
  2. Check all of the following connections:
    • The connection from the power cord to the wall outlet.
    • The connection into the power adapter from the power cord.
    • The connection from the AC adapter to the notebook power socket.
  3. Press the power button again to test the notebook PC.
If the power indicator light still does not turn on, then the AC Adapter needs to be replaced. Contact HP Service and Support for further assistance. Power socket LED or power indicator light is on but the notebook does not start If notebook power indicator light (LED) is on, the AC adapter is working correctly. The problem is a result of a hardware failure in the notebook itself. In some cases, reseating the memory module (RAM) may solve the problem.
