Hello.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

What causes red led on starting?


Remove Power Cord then press and hold the power button for 30 seconds, then put the cord back in and try to start it.

When you press the Power Button are you hearing the fans run, the disk drive running, the cd drive click and the light on it comes on for a second or two?

Anything shows up on the LCD Screen?

If you press the power button and absolutely nothing is happening then you most likely have a bad power supply.

If you press the power button and you start hearing beep sounds or blinking lights in a continuous pattern (ex. 1 long followed by 2 short) then you have a motherboard issue. Those beep sounds and blinking lights tells the technician what is going on with the computer.

Toshiba satellite L305-s5955 power turns Problem with the PC Laptops Toshiba satellite L305-s5955 power turns on, fan turns on. screen stays black. Will not power off with button. Power supply working....


Hello Kristi,

I'm not sure if this will work, but worth a try. It appears that your power up settings have got messed up somehow.

Put it all back together, batteries and charger. It will try to boot after a fashion. Just give it a couple of minutes to try and do what it should. If it still hasn't come on properly, press and keep pressed the on/off button until the laptop turns off (about 5 seconds). Leave it a couple of minutes then try and turn it on again normally.

After this, I'd need to be able to look at what's happening to help any more.

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.

My Python will start the truck and it will run for around 20-3- seconds then shut down. Then start back up then shut back down. It does this three or so time and then stops. What can I do? I have a 2000...


it sounds like the tach needs to be relearned.....if it's still connected. find your valet button, start the truck with the key, then push the valet button down for at least five seconds, the led should light up solid if the tach is learned, once the led lights up you can release the valet button and turn off the truck. it should remote start fine. hope that helps

HP Media Vault - Power on / fan on / front panel indicators off


I read a bunch of material found on the web. Primarily this led me to believe that the Lynix flash OS has some issues (to say the least). After carefully testing out the mom board voltages I decided that there was probably a software boot issue.

I read this at k0lee.com/mediavault/
"The MV1 has a hard reset which severs the tie to the startup.sh script that calls any of the installed software." The material on this site also indicated that the stored files would not be affected by a hard reset. So what the heck... nothing to lose. I unplugged the power, pressed the reset button and then applied power. Held the reset button for > 5 seconds. Held my breath for 30 seconds and the disk light started to flash on the front indicator panel. After a minute or two of that, the OK light came on. I pressed the power button on the front panel and the it responded. Another miracle? Hmmm. The MV shut down. I connected to the LAN and powered back on. Every thing worked fine.

I guess... there was a space issue / startup parameter corruption / enemy electron in the mix that was passed over with the hard reset at start up. Since there is on access to the OS boot process, (or source code) this is pure speculation. Although, it is reasonable speculation. Chao!
