The problem is caused by the inverter board, "just below the screen" is more than likely the problem, or it is the backlight behind the LCD display, "built in" less likely.

SOURCE: where does the sim go

Hi tefordgal12,
I see you have a SIM that you want to use on your compaq system, I checked in you system specs online and it does not show that it has a 3g modem on it on the issue.

  • On all Laptops the 3g modem can be found inside the system, if you remove the battery you may see a slot for a sim card in the battery bay.
  • All Laptops have the 3g modem in the battery but not all Laptops have a 3g modem installed on it some may have sim slots but does not have the 3g modem installed in it
  • Call HP regarding this concern since they can answer our question most accurately if you give them the serial number of your Compaq Laptop.

I hope that the information I provided helps.
Thanks, have a great day.

Have you tested this laptop using an external monitor? If your laptop works good with an external monitor, it means your laptop screen is dead and needs to be replaced. If the external monitor displays black screen , it means there is something wrong with the GPU and or motherboard.

Thanks. Compaq Presario F761 US: When I hit the power button, it comes on for a split second. That's it. Help.........


I'll give you something to try :
using a bright light florescent ,lcd, etc. shine it right on the screen. Look in the center of the screen for the windows logo (might be barely visible).
If this is the case, you either have a bad inverter or the CCFL in your lcd panel is bad. If it is, re-post and we can walk you through troubleshooting or replacement.

My Brand New Compaq CQ56 power light is on, wireless light is orange cap light is on, but the screen is blacked out??


I would suggest returning it to the store if its brand new, as this could be a problem with the video card or screen both of witch can be costly and complicated to fix. If it is new the store is legally obligated to exchange the laptop for a new one or refund your money.
