Question about Compaq 100GB Laptop for Presario 900 & 1500 Series Refurbished (GPOHDC1500100R) Hard Drive

1 Answer

No screen power

When I turn on my laptop, it powers up but the screen is black. I can quickly see the "Compaq" logo but nothing else. I know the laptop works because I hooked up a monitor and I can see the screen.

Any suggestions?

Look a the screen real close, if you see a faint dark version of the image, this could be a backlight issue, otherwise a screen cable or a logic board issue. Backlight repairs are somewhat difficult. As much as I would like to be able to tell you a quickfix that will solve backlight the problem, it's a pretty arduous repair that requires 1-2 hours for a trained person. It's feasible to do it yourself if you're tech savy, but you'll most likely have to google for guides that show you exactly how to replace the backlight step by step. Check on how to take the screen apart and make sure inverter is still connected properly. If the inverter is connected and you still don't have light, then you have a backlight issue. I work for Computer Repair NYC and i have to fix this problem a lot, it's so easy to break the lightbulb in the process.

Laptop black screen


You turned on your laptop and horrors upon horrors, the screen is BLACK! You see that the laptop has power but besides that nothing is happening.
I want you to know that there is a very good chance you can get out of this situation quickly and without any cost. This fix works on all brands of laptops:


• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS
That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen.
After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.
Replace your battery.
or if wont start
Here are the fix steps:
1. Turn off your computer
2. Disconnect every wire from it (including power)
3. Disconnect the battery from the bottom of the computer.
There will be two tabs labeled 1 and 2.
4. Re-plug in the power wire. (the battery should not be in the computer)
5. Turn on the power. The screen will work. Choose start windows normally. (if you get that screen)
6. Go to Control Panel -> (Mobile PC) -> Power Options -> Under Balanced choose change plan settings
7. Choose Change advanced power settings
8. Find Processor power management and change the minimum processor state from 5% to 100% for each On battery and Plugged in.
9. Click Apply then OK
10. Shut down you computer.
11. Disconnect the power cord.
12. Re-install the battery on the bottom of the laptop, plug in the power cord, and restart the computer.

Hi i have a compaq presario laptop and after it stars up the screen just goes blank


Hi there,
do you still see the compaq logo and does it show you the windows boot up screen before it goes blank?
OR
do you see anything on the screen at all after pressing the power button?
Check if the laptop is receiving power. If it has power and you can't see anything on the screen it could mean that the LCD assembly or the Video card of your laptop is bad.
If it goes to the compaq screen and then to windows logo before going out, try booting into safe mode and once there uninstall the video driver from the device manager because that means the resolution was set to something higher than the display could handle.
If it restarts after showing the compaq screen try reseating the memory, hard drive and wireless card of your computer put them one by one and try turning the compter on after each part you put back to check which component is point of failure.
Otherwise you have a bad motherboard and it may have to be replaced.
Hope this helps!

My screen is completely black when i turn on my power button, the light comes on and the fan runs but thats it.


This sounds like a motherboard problem, remove main battery and power supply, now press power and hold for 40 seconds, release and install power supply and battery, any change, if not! remove hard drive to see if screen logo will come up, if no! swap out the ram one at a time. If none of this works, it points to motherboard issues.

When I turn it on sometimes it comes right up other times I get nothing but black screen. I bought it used the seller says it was working fine but I downloaded some upgrades and it has been funky ever...


Hello sir, hi the compaq pro signia is a good laptop, but im not sure if you had a good deal with it, as I see it, your laptop system board has serious problems with its system board and power supply board. The failure of the unit to respond quickly on power up is already a sign of system board defects, You may need to thoroughly check the system board for faulty capacitors. which would cost you extra for repairs. Try to bring it on a laptop service center for diagnostics.

Laptop won't start up


It sounds like your laptop is using it's external VGA adapter for its main display. Try holding down the Function (FN) on your keyboard located on the bottom left hand side and pressing F4 at the same time.

Usb ports not working


You may need to turn on USB emulation in the system BIOS. To do that you'll need to power the system down. When it first turns on you'll see the Compaq logo with instructions to enter setup somewhere on the screen (I can't remember if that model asks you to hit F1 or F2, try both). Once in the "setup" you'll want to look for USB support. More than likely it's going to be in the peripherals screen.

Also, I recommend downloading and updating the BIOS to the newest version. You can get all the downloads for your system on the HP/Compaq website.
