Itz may b caused frm many internal hardware cause, like the battery(main/cmos); ram; sm section of the system board; ccfl; inverter circuit; or even the lcd....

howevr, before proceeding to complex test to verify the current status of ur laptop, at 1st all u need is to put on the laptop to charge for atleast 4hrs..(the gauge status may show u a pseudo process)..
if u r a professional, remove the ram(s) from itz slot(s), gently rub itz connector teeth using a rubber to remove carbon or oxide formed if any..
connect it to a external monitor n see if display is coming..
check the internal system battery to b above +3v..

so itz always better to hv supervision..frm ur system admin/vendor/good or authorized service center....

Hi,

Take out the battery and try booting the machine on AC power only. If the machine boots up then let the operating system load up, the shut it down. Remove the AC jack and put the battery back in again, then power it up.

If it boots all is well if it doesn't then there could be a problem with the battery.

Please let me know how you get on and good luck.

    Hi,
    If the laptop won't start on AC power only then there is no point in charging the battery as you will be wasting your time.

    What you could do is remove the system memory, clean the brass pins and the slots and then re-seat them/it.

    Then try to turn the machine on.

    If you still don't have no luck and your not computer savvy i recommend taking the laptop to a reputable repair store and ask them if they can clear the CMOS.

    Regards.

How do i fix my LCD?


Hi,
I have got a hp pavilion dv5000, when I turn on it the screen goes blank.

Power led glows, I hear for a few time the fan, disk led flashes intermittently and also I feel that the DVD player tries to load.

If I try to click on caps lock or num lock, leds don't respond to commands. I tried the hard reset pressing the power button for 30 seconds with the battery and the power removed. Nothing to be done by connecting an external monitor....

What can I do ?qqb002.gif

Thank you

I have black screen


If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

It seems there is no booting as the memory is not responding or the hard disc is not booting up. Please check on the back up CMOS button cell battery on the back side of the laptop. replace if the voltage is low.
Also remove and reset the memory, if not you need to take consensus to know if this can be the hard disc, memory or the motherboard.

Boot up beep and blanck screen


The beep patterns always tell you what the problem is, but it depends on what kind of BIOS is in your computer. You can take a look here, maybe you find what is the problem with your machine: http://www.pchell.com/hardware/beepcodes.shtml

Laptop not booting up and nothing showing up on the screen


What leds you can see blinking on laptop? Can you hear any bootup sounds? Sometimes my laptop hangs on standby or hibernat, then screen is black and some leds may blink. Usually i need to take charger and battery off for 10 seconds and boot up again. If that dont help then there must be some hardware damage.
