Laptop LED Blink on Startup
There are many reasons that a computer does not startup or boot into the Windows operating system. If your computer will not start or boot, you will see or hear symptom to indicate the general area of the problem.
Startup Symptom: LEDs blink but does not start
The blinking LED lights on newer computers, or the beep tones on older computers, will help support agent determine what hardware component is not responding properly. The exact meaning of each code varies with the model, and the user cannot change any of the blink or beep codes.
DO THESE FIRST - Perform a hard reset.
If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.
1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery and then press and hold the power button for at least 15 seconds.
3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Identify the number of blinks or beeps
When there is a start-up problem and you see LED lights on the keyboard blink a few times (between 1 and 8 blinks) do the following actions.
Table of Sample Blink Codes
The following table illustrates the meaning of blink codes used on some notebooks. The blink or beep codes on your computer may have different meanings.
Meaning of Sample Blink Codes for some EFI Notebooks:
1) Number of Blink: Continuous Glow, Blinking LED: Battery power LED, Component: Battery,
Error Condition: The AC adapter is attached and the battery is charging, but does not yet have sufficient charge to power the notebook.
2) Number of Blink: 1, Blinking LED: Caps Lock/Num Lock, Component: CPU,
Error Condition: CPU not functional
3) Number of Blink: 2, Blinking LED: Caps Lock/Num Lock, Component: BIOS,
Error Condition: BIOS corruption failure
4) Number of Blink: 3, Blinking LED: Caps Lock/Num Lock, Component: Memory,
Error Condition: Module error not functional
5) Number of Blink: 4, Blinking LED: Caps Lock/Num Lock, Component: Graphics,
Error Condition: Graphics controller not functional.
6) Number of Blink: 5, Blinking LED: Caps Lock/Num Lock, Component: system board,
Error Condition: General system board failure.
7) Number of Blink: 6, Blinking LED: Caps Lock/Num Lock, Component: BIOS,
Error Condition: BIOS authentication failure.
8) Number of Blink: Continuous blink, Blinking LED: AC power adapter LED, Component: Power adapter,
Error Condition: Insufficient power
Common solutions for issues that cause blinking LEDs or beep tones
When the computer can boot into the BIOS, run the memory test to identify other issues.
Check for loose connections and test the memory
Blink codes are often displayed after a user adds memory to the computer but does not seat the module properly. The LEDs may also blink error codes if a hardware component is loose because the computer was dropped or jarred. The problem could be that the stick of memory or one of the memory slots has a bad connection.
Check for loose memory modules
If a memory module is loose or is not making good contact with the memory slots, the computer does not recognize all of the memory. Reseating the memory module may resolve memory failure errors.

Apple has a variety of 'beeps' (sound) and 'blinks' (lights) for both computers and monitors. Your 3 beeps (wild guessing here) could be as noted in this link below ... which will also steer you in the right direction. Note too, that blinking lights - can have a pattern (3 blinks: short-short-long, for example). These also have specific diagnostic meanings and you might make a note before searching.

Link to some ref on blinks and beeps is here (a paste follows this note too):

For future reference:

Power-On Self-Test Beep Definition - Part 1 - http://support.apple.com/kb/TA43884

Power On Self-Test Beep Definition - Part 2 - http://www.info.apple.com/kbnum/n58442

The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).

If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.

1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable

In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.

You can also run Apple Hardware test from your original installer disc. Sometimes with RAM it is just easier to pull units and test them individually.

Computer will not start


It all depends how many beeps there were.
From http://h18000.www1.hp.com/products/quickspecs/12253_div/12253_div.HTML
Diagnostic LED Explanation Table Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode

I have only really come across 4 beeps = order new Power Supply or 5 Beeps = reseat the memory and hope it works

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.*

Ibm thinkpad turn on no work


If you're not getting any external display action then that means it's probably a motherboard issue / hardware issue.

First thing you're gonna want to try is reseating the memory and trying to boot the computer with the battery out.

Second, if that doesn't work next thing you can try is removing the cmos battery (with the battery and power adapter out) and letting it sit for 5 minutes with the cmos battery out.

Also, do you get any led lights or any kind of action from the laptop (fans, beeps, etc.)?
