Well. I've run into a bit of a problem. Having a computer with a damaged screen, I figured there was no way to be able to see until Windows/Ubuntu loads. That's a problem when I want to install Windows 7 over Vista. I can't see at the boot screen. The only way I could is to have the BIOS default to the VGA external monitor. I looked it up and found out that I could take off the screen and if the computer doesn't detect a LCD screen, it should default to the only other choice, the VGA input. Unfortunately, I didn't know that taking off the inverter causes a system to stop working. The machine turns on for about 3 seconds, then dies. Upon attempting to replace it, I learned that the only part that connects to the actual motherboard is two black and white connectors that connect to the wireless card. This is only my second time messing with laptop hardware or computer hardware in general so... before I do any more damage, if I do connect the inverter up again and connect the two wires from the screen back into the WLAN card, would it still cease to register the LCD monitor as a displayable output?

Hello rodax and welcome to Bleepingcomputer.

Just a general question before I go into any other advice or suggestions, have you considered replacing the inverter?

Is the option possible for you to do financially?

Bruce.

Oh, there's nothing wrong with the inverter in the first place. The backlight would light up fine if there wasn't huge hole in the screen. I can still see a small edge of the screen lit up well. I just want to know if plugging the inverter back up would still produce the result of the BIOS defaulting to the external monitor if I don't plug up anything else.

Okay so I take it you are not interested in repairing this screen.

I personally am one of those people who does not like using any electronic devices that has electrical problems.

It is not unheard of for even 'battery' operated devices to over heat and start a fire.

But I will answer your question off the record, but you assume responsibility for the out-come.

I know that sounds absurd in a way, but I have been in the electronics repair field for over 38 years now and I even tinkered with electronics as a hobby when I was a young teenager, so believe me when I say using and operating faulty electronic devices can actually cause a fire, this can happen with battery operated devices as well.

As a professional, it is hard for me to recommend anyone to use faulty electronic equipment, so please understand where I am coming from here.

I do not recommend using the laptop in its current state, however, if you wish, you can reconnect the wiring if you so wish to do so.

If your screen is damaged, and you value this laptop, I would recommend locating another screen for this laptop and replacing your current one, then hook everything up as it is supposed to be.

You can look on line and do price comparisons to find a cheaply priced replacement, this will also allow you to take the laptop away from the house, which is what laptops are intended for.

If you were able to use the laptop with the two wires hooked up and using an external monitor, then please feel free to do so. I can not guarantee safety doing it this way however.

Bruce.

I understand, but I'm not using the screen, really. That's why it was removed. But it might have to be halfway reconnected to get the result I want, which comes to my question, which still has not been answered.

Okay sorry about that I thought I had answered your question, but I'll try answering it a different way.

Because I can not determine through the Internet just how extensive the damage to your screen is, I can only suggest you try and see if it works.

To my understanding you said it did work out the way you wanted it too. I realize you are only experiencing problems when the system is first booting up and it is defaulting to the screen built into the laptop until the BIOS switches the images to your external screen.

If you are comfortable using the laptop this way, then that is fine, but you would have to experiment and go with what works best for you.

Bruce.
