That is a security configuration on HP Laptops, depending on the way they blink is the problem your machine has.

Here is the web page where this info is posted, in case you need more info, hope this helps you to determain.

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008. On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes. The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved. Battery power LED blinks The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition. Battery Power LED Component Tested Error Condition Battery power LED off, and Caps Lock/Num Lock off Battery or AC Adapter AC adapter not connected or failure

Battery low charge or failure Battery power LED blinking Battery Insufficient charge on the battery When new computer is used for first time, the white LED light for the AC power connector blinks. Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.

To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer. LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

While watching my sony KDL-46NX810 TV its suddenly shut off and starts blinking 3 times red standby light. Please have me inform, what this error means and how to repair or what to replace on my...


Hi Gerard,
3 flashes of the led light on most KDL series is a power supply malfunction. To confirm the error code, lets access the self diagnostic screen by following the steps below.

Unplug the unit from the outlet for 30 minutes and then plug it back in and check if the symptoms remain the same. Wait until the led light stops from flashing and then press in rapid sequence the "Display", "Channel 5", "Volume (-)", "Power" button key on the remote control. Self diagnostic screen will be display. Let me know the result.

BLINKING GREEN LIGHT AND WILL NOT POWER UP


You can check the Error code by doing the following.

On the Front panel hold down the Device and Menu Button for 5 seconds. The LED light will then start flashing the first set of flashing lights is for the "1"5 part of the code it will then pause for about a half second and start the ones place 1"5". The code will repeat 5 times before going off.

The Error Codes: 12 - Normal Operation; 21 - X-Ray Protect; 22 - Short Protect; 23 - Loss of Horizontal Deflection; 24 - Loss of Vertical Deflection.

The problem may also be in the power supply when you first plug the device in check how many times the Led blinks if it blinks for just over a minute the power supply is working fine. If the Led blinks repeatedly and does not stop the DM is not running.

Ok 7 red blinking led, remove the back cover of the TV. Looking at the power supply in the upper left of power supply. If everything is working fine you will see a solid green led if there is an error, you will see this light blinking also. Right below this led on the power board you will see a list of numbers 1-13 this will give u the problems that this led flashing problems are. More and likely u will have a problem with VSET or VSCAN. Which is connected to the Y-Main and Y-buffers,( the board that is too the left of the power supply if u look on the small print on this board you will see that it reads. 42HDV4 Ymain and the 2 small boards connected to it are Y buffers. To be sure that this board is bad if the TV keeps going into error protection. unplug the power supply and wait for the led to stop flashing. Disconnect the cable that plugs into Y-Main from the Power Supply. It should stay running. If u remove this board and look underneath u should be able to see where this board is getting hot. Easiest fix is to order a replacement. Y-main assembly.

Green led light flashing on 700p proview flat panel and no picture


Any high switching power supply of the same voltage and amperage rating will work for you. You may have to cut the end off of your old one and wire it to the new one to make it work but don't waste your money buying a specific power supply.
Good Luck!

Presario 6350CA won't boot


I don't know that I'm going to be a great deal of help, but here is the link to the support site for you Presario:

http://h10025.www1.hp.com/ewfrf/wc/product?product=390426&lc=en&cc=us&dlc=en&lang=en&cc=us

Here's a link to another page on the Compaq site that specifically talks about power supply problems:

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph06788&lc=en&cc=us&dlc=en&product=390426&lang=en#N514

They discuss a flashing power led on this site, but I believe they are referring to an led on the power supply itself. Perhaps the led on the keyboard and the led on the power supply are both flashing...

Good luck. I hope this helps.

Flashing Lights when powered down


The flashing LED is because your system is in "sleep" mode. By default windows Vista puts your computer in sleep. What this means is it doesn't shutdown the power completely it leaves a little going through certain computer components (more specifically the ram) to speed up the boot time when the power button is pressed again.

In XP a the default shutdown scheme is a complete shutdown where power is turned off after the shutdown process is done. If you are using XP you are putting your computer to sleep when shutting down.

As for the boot problem. Newer motherboards have an LED on the actual board to indicate that it is receiving power. If it is of either the power supply switch (at the back of the case) if off or the motherboard connection is loose and the shaking makes it fall into place. (Shaking is usually not necessary and indicates a problem...)

There are a few possibilities I can deduct from your description:
  • the connection from your power supply to your motherboard isn't properly seated and is causing this
  • the power supply switch (not the case switch) is being  turned off and results in the computer taking a few seconds before the internal LED become solid
  • ... the dreaded sign that the power supply is failing and is on it's last legs...
My suggestion is to check all connections and if that doesn't work borrow a power supply from a friend and swap them to see if it boots properly.

(If a friends with a spare power supply isn't an option a local PC repair shop should be able to help you out... but probably for a fee...)

The flashing power switch and power supply LED on the rear in conjunction with a power failure or surge indicates that there is a defective component; typically the power supply, motherboard, memory, processor or modem. -Disconnect all the power supply leads, drives, and motherboard as well as any USB, firewire and other external devices. -Plug in the 115v power supply cable and look at he LED on the back of the power supply. If it is still flashing the power supply is bad and needs to be replaced. -If it isn?t flashing then unplug the power supply plug in one device, plug in the power cord and watch for the flashing LED again. If it?s flashing you?ve found your culprit, if not move on to the next component and repeat the process until you?ve found it. Don?t forget your plug in cards could also be the problem. Good luck and let us know if you have any other questions. As always please don?t forget to rate this posting.
