I have a dell d600 laptop. it won't boot up at all. if you push power button, the caps lock light blinks a few times and then it shuts off

If you want to keep your important data, use some softwares can solve thewindows won't startproblem most quickly, and no data will lose. Besides, it is very easy, even the people who lack of computer knowledge can deal with windows won't boot issue.

Yes this can be a opverheating problem that's why sometimes it boots up, if the processor is not working fine because of overheating you check first the cooling system of your computer liek the fan if they are working fine because if the fan is not working the way it should be working oeverheating may occur and will result to this problem...

Hope that helps.......

hi
maybe you have change the keyboard , it is failure

Remove 1 stick of ram and turn on, if no! take out the second one and put back the first, and power on, if okay you know the 1 stick is bad. Remove main battery and power on, "long shot" if no change chances are it is a motherboard issue.

Replace the Ram with known good sticks. This can cause a startup failure. Hope this helps.

That icon is the indicator for Caps Lock (aka Shift Lock). When in the operating system (Windows), you can turn the icon on (or should be able to) by pressing the CAPS Lock key, and turn it off by pressing the CAPS Lock key again.

I would try clearing the cmos battery. It's located under a small door under the laptop battery. Unhook the wire (laptop unplugged) and let it sit for 20 minutes. Hook it back up and try to power up. If that doesn't work www.pcrepairhelp.net has techs that work on laptops.

The flashing caps lock is an indication of a failed POWER on Self-Test (POST)

Remove the HDD, Battery, AC adapter, RAM and Modem

Press and hold power button for 15 seconds

Connect AC, see if you get any beep codes. If you do, power off, disconnect power, insert RAM, connect AC and reboot. If system boots, power off and add hard drive. If it doesn't, replace the motherboard.

If the system boots with RAM, but fails to boot with HDD, replace HDD 1st.

you can try to replace the motherboard, which is apparently totally UnHappy

the middle one with the A is Caps Lock....

Try removing the Battery from the System.... There is a power indecator on it....... Push the button on the battery Five lights full battery.... No Light Dead.... If Dead Your Power supply might be at fault....

Is the power Supply Light Lit? If No.... Bad Check connections..From Wall to Brick ect.... Still No... PSU Looks Bad....
