I am currently working on a Dell Studio 1555 for a customer. They asked me to remove the screen and turn it into a laptop they can use on a tv hookup. Upon doing some research online, I realized once removed the computer will beep consecutively until the problem is fixed. Now my question is can I do anything to remove the beeping used for techs to diagnose a problem so he can use this setup on his tv. I have tried removing the CMOS battery and resetting the computer to factory settings. I'm at a loss as what to do. Any help would be much appreciated. :)

wouldnt hurt to find out what the beep code is specifically, and fix the problem. chances are, it actually needs a screen plugged in to boot up. . .

the 8 beep is a broken lcd code. I removed the lcd but customer wont pay for a new one.... so i was interested in the notion of disabling the beeping all together, but i havent the bugger of a clue as how to.

Well with the strap disconnected from the lcd screen this is causing a open loop for the sensor or bios thinking there is a problem with the monitor and no power/signal is going to the VGA or HDMI ports. Hmm I wonder if there is  plug you can get to hook to the strap and close that loop and trick it. Yeah, I don't think that will work because the vga and hdmi ports aren't going to work till the OS is booted. I could be wrong though UEFI bios has come a long ways in development. By the way don't mess with the circuit board inside the LCD itself. That's a power inverter with upwards of 2Kvolts and would happily kill you if you get electrocuted from it.

Well I have a old dell 610 XP on it and I would boot the system and from there hook svid or vga external port up to the tv. Then in order to get it to output to tv I would press the FN (function key) and one of the F keys that has a monitor icon on it. After that I can close the lid and use a external mouse/keyboard, use the DVD player etc.
