Re: Power won't stay on.
There should be Two power wires connected one to constint power and One should be hooked to the power for ignition I also believe that there is a saftey that turns its off after so many seconds, There should be a way to disable that function in the owners manual, I sure Hope that helps you out Happy Holidays If not Lets fix it somehow just write back and let me know if that works..

Hello, The flashing power light and very slow display is an indication that the internal power supply board is failing. This is usually caused by bad filter capacitors on the board. You should be able to repair the unit by replacing the bad capacitors.
You are encountering a "POST" (Power-on self test) problem on your laptop. Here are the steps that you can try.
- Remove the battery and the ac adapter then press the power button for about 15 seconds. Try to power on the unit using just the ac adapter. - If you have an external monitor, kindly hook it up and check if you will get any display on the external monitor. If you do, the LCD needs to be checked, if not, then you may be having a problem with the motherboard. - If you can reseat the memory module and the hard disk drive of your laptop then that can help as well.
I hope this helps, please inform me if this solution works or not. Thanks.
What you are experiencing with your laptop is "POST" (Power-on self test) issue. Here are some steps which you can try.
- Remove the battery and ac adapter (as well as external peripherals attached), press the power button for atleast 15 seconds, try to power on your computer again.
- If you have external monitor, hook it up. Display on the external monitor would mean that you have a LCD issue (check LCD cable, LCD inverter and LCD backlight in this case). No display on the external monitor would mean that you need to replace the video card (if dedicated) or replace the whole system board (if integrated).
- Try to reseat or replace the memory module as well, it might help.
This sounds like the power inverter is failed.. It's what pumps up the power for the light in the monitor.
You could try unplug the sound bar from the back of monitor if you have the sound bar installed. Just a maybe..
To fix the inverter (replace) is usually better to buy newmonitor unless you do it your self.
The defective LCD Backlight inverter will cause the following symptoms:
No Display, but Power Indicate light stay on green (Or Blue).
Screen flash on and off and the power indicate light stays on green (or Blue).
has to do with power i can get myin to stay some times but then the same thing hapens to me u have to buy a new power board wich is esy to replace and i have had min as a second screen for like 4 or 5 years now with no probloms so its just from over use..
you have problem wit the lamp just plug in another once you removed the back cover and if the lamp stays on the it is 100%. you do not need original lamp. Any 15" lcd lamp that fits will do the job. HA HA well done
IT IS TIME TO BUY A NEW MONITOR. I KNOW ALOT OF OF US CANNOT AFFORD A NEW MONITOR EVERY TIME ONE BRAKES, I HAVE FOUND THAT SECOND HAND STORES SALE THERE MINITORS FROM 1-2 DOLLARS PER INCH, I PICKED UP IBM FLAT SCREEN 20" AROUND 20.00 USD. AND IT STILL RUNNING AND I HAVE HAD IT FOR A YEAR OR MORE NOW.
The only troubleshooting step I can offer here, is unplug it, and press the power button down for about 15-20 seconds, to flush any trickle power remaining in the unit. Then plug it back in, hook it up and try turning it on again. If this solves it, great! If it doesn't though, then I would check either with HP directly or with your place of purchase to see if your issue can be covered under limited/extended warranty. If you are out of warranty though, LCD repairs tend to jump pretty high, and usually end up being more than what the monitor is worth, so it may be more economical to replace it at that stage.
Rarely does a monitor go out due to drivers. Try another monitor and verify that it isn't the computer (it isn't). If the power light goes out it is the power supply (usually inside) the monitor. If the light stays on, it will most likely be the backlight power unit. Browse the internet for the model and parts. Newer units are difficult to find.
