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.

Hi,
If you are referring to the green light on the system tower and is blinking the problem could be the system is in stand by mode.

Turn off the computer by pressing on the power button on the system tower for 10 seconds.

Disconnect the black power cord at the back of the system tower and then again press the power button on the tower for 10 seconds. There would be no activity on the tower when you do this.

Reconnect the power cord and then power on the computer to see if the issue is resolved.

My d530 minitower powers off unexpectedly and red lights starts to blink on System's LED//


Hi Kindly let me know how many times the red light blinks
Condition Code Service Actions Processor thermal protection activated. Power LED blinks red twice, once a second, followed by a two second pause.
  1. Make sure the computer air vents are not blocked and that the cooling fan is running.
  2. Open the hood, press the power button, and see if the processor fan spins. If the fan is not spinning, make sure the fan cable is plugged into the cable header on the system board, and that the fan is properly installed and seated.
  3. If the fan is plugged in and seated properly, but is still not spinning, replace the processor fan.
  4. Reseat the processor heatsink and make sure the fan assembly is attached to the heatsink properly.
Processor is not installed. Power LED blinks red three times, once a second, followed by a two second pause.
NOTE: This condition indicates a missing or improperly installed processor, not a defective one.

Make sure there is a processor in the system. Reseat the processor and verify that it is installed properly. Power failure (power supply is overloaded) Power LED blinks red four times, once a second, followed by a two second pause.
  1. Check the voltage selector, located on the rear of the power supply, is set to the correct voltage (the correct setting depends on the region).
  2. Open the hood and make sure the 4-wire power supply cable is fully connected to the power connector on the system board.
  3. Check if a device is causing the problem by removing all attached devices (such as disk drives and expansion cards), then power on the system. If the system enters POST, power off and replace one device at a time, repeating the procedure until the system power failure reoccurs. Replace the device that caused the failure, then replace each of the other devices and confirm that they are functioning properly.
  4. If you cannot isolate the failure to a specific device in the previous step, replace the power supply. **
  5. Replace the system board.*
Pre-video memory error. Power LED blinks red five times, once a second, followed by a two second pause, and five simultaneous beeps are sounded
  1. Reseat the DIMMs in the memory slots on the system board, then power on the system.
  2. Replace the DIMMs one at a time to isolate the faulty module.
  3. Replace 3rd-party memory with HP memory.
  4. Replace the system board.*
Pre-video graphics error. Power LED blinks red six times, once every second, followed by a two second pause, and six simultaneous beeps are sounded. For systems with a graphic card:

  1. Reseat the graphics card and then power on the system.
  2. Replace the graphics card.
  3. Replace the system board.*


For systems with integrated (on-board) graphics, replace the system board. PCA (system board) failure. ROM detected failure prior to video. Power LED blinks red seven times, once a second, followed by a two second pause, and seven simultaneous beeps are sounded. Replace the system board. Invalid ROM based on bad checksum Power LED blinks red eight times, once a second, followed by a two second pause, and eight simultaneous beeps are sounded.
  1. Reflash the ROM using a ROMPaq diskette.
  2. Replace the system board.*
System does not power on. No beeps or blinks since the system is not functioning. Press and hold the power button for less than four seconds. Perform the following steps depending on whether the hard drive LED turns green.

If the hard drive LED turns green, then:

  1. Make sure the voltage selector (which is located on the back of the power supply) is set to the correct voltage for your region.
  2. Remove the expansion cards one at a time until the 3.3V auxiliary light on the system board turns on. If removing a card turns the light on, replace the card and then see if the system works.
  3. Replace the system board.*


If the hard drive LED does not turn green, then:

  1. Make sure the computer is plugged into a functioning AC power outlet.
  2. Open the hood and make sure the power button is securely fastened in the power harness and that the harness is connected properly to the power connector on the system board. In other words, make sure that the power button is making contact with the power circuit.
  3. Make sure the power supply cables are connected properly to the power connectors on the system board.
  4. Check to see if the 3.3V auxiliary light on the system board is not turned on, replace the power supply. **
  5. Replace the system board.*

Add internal bluetooth to a Toshiba portege M400


The review below says bluetooth is built in, please confirm the exact model number.

The Toshiba M400 is the first convertible tablet notebook we've seen to sport a Core Duo processor. And the 1.83GHz Core Duo CPU at the heart of it, backed by 512MB of RAM, powered it to a benchmark score of 0.90. The other specifications are respectable. The Western Digital hard disk has a capacity of 80GB, while the optical drive is a Matsushita model that will write to all formats of disc, including, usefully, DVD-RAM. Elsewhere, Intel's 3945 802.11a/b/g wireless card rounds off the Centrino specification, and Bluetooth is another plus.
