Hello,
I am working on my friend's laptop, which is an HP Pavillion dv8210us. The laptop is booting up, but the screen remains black. The optical drive also flashes Amber color and makes a winding noise every 2-3 seconds.
Here are the steps I have taken so far from what I've researched.
- Remove the battery, unplug the power cable, and hold down the power button for 15-30-60+ seconds, plug in the power cable and try rebooting.
- Remove the optical drive and try booting.
- Test RAM Modules: Removed top module first attempt, removed second module second attempt, tried swapping the RAM modules third attempt.
- Use a second monitor with a VGA cable, plug it into the laptop, boot up and press Fn+F4 to switch Display (failure).
- Turn off lights and hold a flashlight to the screen to see if there is a dim display (black screen).
The hard drive doesn't make any irregular sounds when booting, CPU fan is fine, and all blue icon LEDs light-up on boot. I have ordered a new dv8210us single-lamp LCD inverter, but the second monitor via VGA not turning on leads me to believe it might not be inverter.
I'm not sure where to go from here.
EDIT: I copied and pasted this from the HP forums since I have gotten 0 responses in 2 weeks. I have replaced the LCD Inverter and that did not fix the problem (assumed it wouldn't since External Monitor did not display either). My friend had stated he replaced the RAM Modules with Used modules a few months ago when he was having issues. This leads me to believe it is indeed a RAM issue, but I also think it may be a bad PC Assembly/ExpressPC.
Thanks in advance for any tips or suggestions.
