Question about HP Compaq Presario C500t Notebook

1 Answer

The power button initially lights up, fans start, then everything stops and the light on the power button blinks continuously. I replaced the cord and the battery. It does the same thing when plugged directly into the wall. Help?

Try pulling the hard drive out. boot the unit if it boots your drive is the problem. if you have replaced the battery and cord . also first try removing the battery and plug into wall and boot unit. if it boots up then you may want to see if anything is fried that connects to the battrery.

Do the fans run? If not the power supply is most likely bad. Hopefully it didn't trash the motherboard, memory and any installed cards. If you can't hear the hard drives spinning up, then it has to be the power supply

I have a fujitsu e8410 which will not start up properly, when i push the start button it shows power but then the fan comes on and the cap num and shift lock leds flash and nothing else. can you help?


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

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.

One bad/faulty lead can cause a computer with lots of problems
replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?

    The purple light is flashing in the front and tries to start and won't turn on. disconnected power cord and held button in for thirty seconds still have same issue what could it be?


    This can be a faulty power supply or a damaged mother board. here's how you can confirm.

    When pressing the power button, inspect the cooling fan that is located on the back of the power unit where the power cord plugs in. if the fan starts then stops immediately, this will confirm a damaged power supply.

    Now, if the fan continues to operate but, the CPU doesn't start to power up and load the OS, thsi will confirm a mother board issue. replace the mother board in this case.

    Hello! Try this:
    1. Unplug the power cord

    2. While pressing the ON button, plug the power cord back in.
    The power light should flash an orange/yellow color.
    Continue pressing the ON button, and press the RESUME button 4 times. The light changes every time you press it.

    3. Release both buttons, and restart the printer.

    The printer should now stop blinking and operate as usual.
    I hope this works for you. OMS
