How do I access the BIOS settings for the P5LP-LE motherboard. The startup key says to press F1, but pressing F1 does nothing.


The instructions say:
"Hold down the F1 key during the startup process and enter BIOS setup to re-enter/reset any custom BIOS settings." I would also try hitting the F1 key multiple times from the very turn on of the computer because the key may have to register at some point after turning on.

Try clearing the CMOS settings as explained on this page, it should clear out any passwords and will set the BIOS settings back to factory settings.

As for "The CPU fan runs normally on boot, but as soon as the Windows flash screen comes up, the CPU fan slows way down."
This is quite normal. On start-up the temperature of the CPU is not being read, when the flash screen comes up just happens to be the same time that the computer recognizes that the CPU is cold and doesn't need to be cooled.

On the "Then the installation program starts running and the CPU Fan speed starts fluctuating wildly from slow to extremely fast."
This could be normal as when files are read from a DVD the CPU doesn't work hard, but when it unpacks the files or does calculations it does work hard. Or it could be that the thermal paste between the CPU and the heat sink is not correct. Either dry , not making contact, or even too much. If the heat is not being transferred that would also explain the shut-down.

My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


It is helpful to have the sequence of the blinking red light. This may help:

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



Note: The front panel buttons must be used, NOT those on the Remote Control.



• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2 second.

• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.



Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

WHAT IS FAN FAILURE


fan failure is when the fan that cools the machine stops working.the error always tells u which fan is not working,usually the c.p.u fan or the system fan mounted on the casing,simply check which one is not rotating and change it.or(not recommended) if it is the system fan,just go to bios settings and dissable it.hope it helps

Does not boot up, fans start, internet plugs light, clicks on and off.....seems this is a common problem for these machines, what is the fix?


Instructions
  1. When you press the Power button to start the boot process, the LED lights glow while the computer verifies that there is sufficient electrical power to activate the hardware.

    Effect & Solution: When you press the power button, the LED lights on the computer do not glow or the LEDs blink briefly and then stop. There is no sound of the fan or hard drive spinning, and the screen remains blank. The computer will not start if there is insufficient battery or AC adapter power.
  2. The BIOS queries various hardware components used for the startup boot process.

    Effect & Solution: When you press the power button, the LEDs glow but there is no fan or hard drive sound. The LEDs may glow briefly and then go out.

    Or

    The LED lights blink, stop, and then blink a second or third time, but there is no sound from the computer and the screen remains blank. The sequence of the blinking lights indicates a specific error code.

    Or

    A series of beeping tones is heard. The sequence of beeping tones indicate a specific error code.

    If a hardware component has recently been replaced, or if the PC has been jarred or shaken, there may be a loose connection to the memory chips or hard drive which prevents the computer from starting.
  3. The BIOS loads the basic input (keyboard) and output (advanced LEDs / display screen / boot drives) devices into memory.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, but then the boot process stops and a black screen - with an error message - displays.

    The boot check has detected a communication error or conflict with a hardware component that must be corrected.
  4. The BIOS loads the Windows operating system and starts the services that allow low-level control of all of the background operations.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, the HP or Compaq Logo displays on a black screen, but then the boot process stops and a blue screen - with an error message - displays.

    The boot check has detected a hardware driver error or a software conflict that must be corrected.
  5. Control is transferred to the Windows loader to initiate the display of the advanced settings in the Windows environment.

    The Windows logo displays during this step.

    Effect & Solution: When you press the power button, the computer performs all the steps in the boot process, but after the Windows Logo displays, the moving Windows progress bar or the rotating cursor stops moving and the boot process stops.

    An error message may display on a screen with the Windows logo. In some instances, there is no specific error message.

    Or

    A black screen appears and the computer attempts to restart.

    The Windows self-check has detected a software conflict that must be corrected.

WHEN I BOOT UP COMPUTER, I GET A BIOS MENU SHOWING A POWER ERROR. THE POWER MENU SHOWS CPU POWER FAN AT 1467RPM, AND N/A FOR THE POWER FAN. THE "GEEK SQUAD" SAID I HAVE A BAD FAN, BUT DID NOT KNOW WHICH...


The bad fan is the Processor fan, you can see it into your motherboard, you need to replace with a new one, or better check it first there might be some wires that stopped the fan to work, or simply the fan is defective.

Pc sht down stating thermal error. suppose processr fan not working. can this be the cause of the eror?


Most of the time you'll never hear the CPU fan. If you don't hear the normal fan sounds coming from your computer, it is most likely the power supply cooling fan. Hold you hand at the back of the computer where the power chord plugs in, while the computer is running, and test if you feel air blowing on your hand. If you don't, then replace your power supply. Make sure, when checking for a new PS that you get the correct pin count. Best to order from Dell since proprietary systems usually use proprietary parts and a generic PS won't fit in the opening at the back of the computer (alignment of the plug and the fan with the opening, etc.)

I have a Mitsubishi WD-62525. This morning my TV would not turn on so I pressed the rest button. After the Timer light stopped blinking I pressed power. I could hear the fans start than a somewhat loud...


the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note:
The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.


and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure

Re: t40 ibm fan error


Are you talking about the original fan being good or the replacement? If it's the original, then your problem may lie with the processor or mainboard. Try the download first, you will need to access another computer to make a bootable disc for the download to clear it. I believe with IBM you can make a bootable floppy or CD. If you have a floppy for your machine, some don't. Once you've made the disc or floppy, you will need to enter the boot menu, and boot from the proper drive. I'm out for the night, but I'll be back in the morning. Let me know.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
