Well guys, it sounds like motherboard trouble with your laptops.
Try this, try to press the power key and hold for about 30 seconds (after removing the battery). That'll clear the bios to regular settings.
If that doesn't work (which means bigger trouble), then you need to do the following. If your laptop is under warranty (since I don't suggest opening it up unless you know what you are doing) you are going to need to send it back to them, or contact the company you got it from. Next, you'll need some basic info. the motherboard is able to tell you stuff even if it can't boot.
Now the three lights seems and appropriate signal, but let's try pressing the Fn key (the function key which provides things like increasing the brightness and such when held and pressed with another button), and THEN while holding it, turning on your machine. It should give you some beeps, and some flashing lights. These are things you're going to need to record, feel free to turn the laptop off and on again if you can't catch it all. This is info you will need to tell the laptop company involved.

You could also try reseating the RAM chips, which simply involves using a jewelers screwdriver and flipping your laptop over and unscrewing a cover protecting the ram (it usually has vents and is somewhere in the center bottom of the laptop on newer models). If your laptop only has one slot down there we may need to check the top, tell me if it does and I'll walk you through it. Checking your Ram does NOT void your warranty, it's easy to replace. Once it's open, take the two plastic bits holding the chip in place and press outwards away from the chip on them until the chip magically pops up. Then, take the chip out, and put it back in the same way it came out (angle and everything), once in and snug, press it down until it magically snaps back into place, replace the ram cover, screw it down, and try turning the lappy on.

Hopefully this helps. Stay spicy and happy lappying!

If you remove the power adapter and battery, press the power button to discharge any latent power. Plug the power adapter back in press power. If it still shows flashing Caps lock light, it has overheated and requires a GPU rework/repair.

Toshiba Sattlite, boots but black screen. Caps Lock light is on and F10& F11 key is okay.


Corrupted operating system. Start over with a restore disc and if you do not have one buy one you will need it from the factory. Re-install the whole system over again. Insert the disc in the slot and power it on select boot from DVD or CD-Rom which ever you have. Follow the onscreen instructions. John

That is a security configuration on HP Laptops, depending on the way they blink is the problem your machine has.

Here is the web page where this info is posted, in case you need more info, hope this helps you to determain.

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008. On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes. The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved. Battery power LED blinks The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition. Battery Power LED Component Tested Error Condition Battery power LED off, and Caps Lock/Num Lock off Battery or AC Adapter AC adapter not connected or failure

Battery low charge or failure Battery power LED blinking Battery Insufficient charge on the battery When new computer is used for first time, the white LED light for the AC power connector blinks. Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.

To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer. LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

My laptop when I power on, shows a blank black screen and the caps and num lock lights are blinking and the fan is running.


Your hard drive has probably gone bad and it does not have a bootable device to use on start-up.

What do the activity lights on the keyboard of the Dell Laptop C640 represent?


To the right of the power button and below the Dell AccessDirect button are three lights. These have a lock synbol below them. The first one from left to right is signified by a number 9, this light is turned on when the numberical keypad is enables. The center light is signified by a letter A, it is on when the uppercase letter function (Caps Lock) is enabled. the third one, far right, signified by a down arrow, is on when the scroll lock function is enabled.

The device status lights on the far right side near the front of the laptop case. The top light is the power status light, the middle light is the Hard drive activity light, the bottom light is the status light for power management, battery, AC etc.

Start up


yr problem should be from the screen to really confirm if yr laptop is truly on cos u dont just gudge by seing the power led on. to check if yr system is on press the caps lock key or press the fn+num lock key if the indicator led comes on then yr system os on now troubleshoot yr screen by checking the module,connector n fuses. if the caps lock led doesnt come on then yr system just powered on because it saw a power source in that case try to replace the memory(ram) next the processor.
guess this helps
