Hello there, first thing you should do is to check the power cable.You can do that by changing it with PC power supply cable .It is the same. If it turns to be OK then disconnect the VGA cable from monitor and then try to power monitor on.There should be an activity on front power LED. If the power LED is not showing any light at all, then do not go further the unit is not working .Else the power led should blink a couple of times then a window pop up scrolling on the lcd saying :" no video signal" so the unit is OK ..Hope this helps. Cheers.
It'd be a good idea to check if the laptop is actually booting up or not getting anywhere at all. You can check this two ways, fairly accurately.
First of all, the best way to check is to plug your laptop into another external monitor, you should be able to do this with the VGA connector on the left side of your laptop. You can do this with any monitor that's used with a PC. See if the monitor turns on when the laptop starts.
If you don't have an external monitor to try, the numlock, caps lock and scroll lock keys on your keyboard should show that they're active by the LED that shows they're on or not. Turn it on and let it boot up (give it a few seconds or minutes to be sure), then press numlock or caps lock or scroll lock and see if the LEDs for those keys turn on or not.
If the external monitor works, or the LEDs are functioning as normal, it's likely that the monitor has a loose connection inside or that the monitor is entirely broken. Since the monitor is flashing white when you turn the laptop off, it would sound to me that the inbuilt monitor is connected but not working.
If the external monitor doesn't work, and the LEDs for capslock etc don't respond, then it's likely that something else is wrong with the laptop entirely.
It will be helpful to know what happens to narrow down additional help.
fails battery out so leave it out they love to short.
so when it fails test 2 is, hit the F10 or ESC key promptee
went it fails to boot, check BIOS key first, if BIOS fails.
be more clear.
what does it do when it wont turn on.
BIOS dead. screen 100% dead, and not even text
BIOS works even with HDD and DVD drive pulled.
that is the acid test on PCs.
the screen must say, hit F10? or ESC to enter setup, means HP BIOS. it must or power is no good. get a new power pack
the shut down tell me lost power, that can be the power pack 19vdc
or the jack at the mobo if failing to said pack.
try side pressure on that jack if at anytime the power button fails.
it self shuts down, I got that but lets fix , cant boot first.
that is how to fix this.
power on failures, are you saying the power key fails. some times
and the fan does not run every time.?
this old LT uses CCFL back lamps.
that love to fail. so when it shut down did the fan die.
did the HDD stop spinning ear to bottom? if not the CCFL is failing.
using and external monitor proves this every time,
do the flash light trick?
it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.
is the led flashing? if the led isnt flashing but is lit then press the power and menu buttons in together on the front of the set and hold them both in together and see if it flashes a two digit blink code. then let me know what happens. If it blinks constantly let me know that as well
while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.
Occasionally this will not work for me, but if I repeat it it normally works
Hope this helps - my problem is intermitant so it may be different to what u guys have
