After 18 month the computer will not go into POST on a re-start but will start normally when completed turned off.
The computer will have to be restarted after most OS updates, etc. and has worked normally until recently. Now when windows shuts down, some 10 or 15 seconds later the computer begins to start. I shut off the logo to view the screen. The initial black screen with Phoenix BIOS appears with the task bar at the bottom "Del to enter set-up", etc. However the screen is frozen, no memory check etc. Esc, Del, F10, three key boot, nothing will move into POST. It is necessary to shut off power, turn back on again, then press the start button on the computer. POST checks the memory and starts the OS too fast to read the progress. The mother board functioned flawlessly for 18 months. It freezes on hot re-start only. Any help available. Note, all BIOS settings are original except I turned off the WinFast logo to see the screen on start up.
Thank you for the possible solutions. Unfortunately I had an operation on my hand and will not attempt the fix for another week or two. It's hard to work on the computer with one hand wrapped up like a baseball glove.
I'll let you know if the fixes work, asap.Thank you for the possible solutions. Unfortunately I had an operation on my hand and will not attempt the fix for another week or two. It's hard to work on the computer with one hand wrapped up like a baseball glove.

The problem was solved by magic. Tried the above suggestions but the POST freeze on a OS shutdown/restart remained. I cleaned up the inside, vacuum/blow out dust, and wired in a case fan never originally connected 18 months ago. It works without a hitch now.

Re: After 18 month the computer will not go into POST on...
The system in the bios must be set to halt on all errors.
Go into the bios (F2 or Del) on start up and in the standard bios settings, there should be 'halt on all errors enabled.
Set this at off or dissabled.
Next time you boot the pc it will not stop if there is an error and should show you the problem cause in the boot up sequence.
If all else fails follow the previous solution post to clear cmos, to do this locate the 'JBAT1' terminal and put jumper cap from pins 1-2 to pins 2-3 for a few seconds, then back to 1-2.
Start pc reset time and date and if unsure highlight default settings menu enter, save settings then exit and hopefully it will boot into windows.
Re: After 18 month the computer will not go into POST on...
Simple. clear the CMOS by using clear cmos jumper setting or remove the cmos battery and put it again and then change the bios settings as per ur machine configuration.

If I understand correctly, you are referring to a password that is set in the computer's BIOS which comes before the operating system (Windows / Mac / Linux) starts.
Most BIOS passwords can be reset using a jumper on the motherboard. This is where it gets very specific to the motherboard so you should look for documentation on your specific HP model at support.hp.com.
Typically, you move the CMOS jumper to different pins, power on the system and when the POST completes, turn it off, move the jumper back to its original position, and the computer should start without the "power on" password. In short, it removes whatever changes were made to the BIOS.
1. Check n clean battery cables with a battery brush. Look at both ends, if able.
2. Check battery acid level. Add if needed, get a jump.
3. All OK? Then get a battery load-test done free at a parts store.
I have a 2004 Chrysler 300M that makes the ticking noise when first started . . . if you turn the heater control to completely off the noise stops . . .leave it off for about 3 to 5 minutes and then turn it on and it will be gone. . . my chrysler dealer repair service manager can't understand it and didn't believe me when I told him. They tried to tell me it was my motor mounts. My 18 year old daughter figured it out. go figure!!!
Backlight Bulb is out.
You cannot purchase these as a spare part, you must purchase the complete backlight.
Backlight cost is more than or equal to a new TV
You may sell this TV on Ebay (list your exact symptom). Start at 100 you will get about 250. Take this money and buy a new TV.
LCD backlights don't fail often but when they do there are no part available to repair them so you get stuck buying the complete assembly part. This is more expensive than a new TV since LCD prices have dropped so much in recent years.
check to see that it is not overheating. If cpu fan is not blowing (could be frozen up) or if the fan in the power supply is clogged with dust, the computer may be overheating and refusing to some on. If it is dust, arrange to blow it out completely. take off cover and try to start the machine, the fan should turn on the CPU.
maybe your computer has a corrupted file system, memory problems or hard disk failure. I suggest sending your Laptop to Geeks Squad at any best buy location or Firedog at any Circuit city location for evaluation.
I have a Brother HL 4040Cn printer that has stopped working completely with the exception of the side exhaust fan running. This machine has printed low volume of work over it's 18 month period and I have read another post today describing the same problem!! Any ideas? Brother want a minimum of €150 to take a look at it.
