    Hi Tech Support Guys and Gals,
    I was using my Hp laptop and the screen randomly froze. I manually powered off the computer and now when I turn it on, I hear one longer beep followed by two short ones. In addition, the screen doesn't work. If I let the computer keep working and boot up, I eventually hear the welcome screen theme play so it seems like the computer keeps functioning, but the monitor won't work. Any ideas? Thanks in advance

    Do you ever see anything on the monitor at all, like the POST screen or manufacturer's logo before Windows loads?

    If you have a monitor you can use, can you connect it to an external video output on the laptop and switch the laptop to use that output?

    Hi there I do have another monitor and I tried it but the other monitor will not display anything either. And to answer your first question, I never see anything when I turn on the computer, no post screen or manufacturer logo either. I was on Hp's site and they suggested reseating the RAM. I tried but could not locate where the RAM was nor how to pop off the bottom of the laptop where I think the RAM is...thanks for all the help thus far!

    When the screen controller blew on my Acer laptop, the screen went black. However, when I looked carefully from different angles right beside a window, I could just make out the desktop, and I could hear the normal sounds. Mine refused to boot after that, unlike yours, but I'm wondering if it's the same thing.

    From what they tell me, the screen controller is located in the screen casing at the bottom under the screen, and is an inverter module that controls the power to the backlight. I'm thinking if it is this controller that's gone, and it has to go through this controller first, then maybe that's why it's not showing anything on the other monitor as well? Hopefully someone here can confirm if that's how it works.

    My laptop was still under warranty, so they had to replace it for free since this was a hardware issue.
    Hope this isn't leading you on a wild goose chase, but it's something else to look at, anyway. :)

    You can look at Beep codes here-

    http://www.computerhope.com/beep.htm

    It seems with an Award bios that 1 long and 2 short beeps "Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information."

    Could be trouble with your GPU....

    Yea I figured this might be the case. I think I missed my laptop still being under warranty by about a month....super. I'm not as familiar with the components of the laptop and taking it apart but does anyone know any step by step process I could do to fix it myself or is this a new part I need and that I'll have to send the computer back to Hp? On the Hp website it suggested reseating the RAM, but I haven't the foggiest how to do it...

    As you are not familiar with taking apart a laptop it might be best to give the supplier where you got the laptop a phone and if it is only a month out of warranty try and see if they will fix it for you anyway..you never know might be worth a shot!!

    I feel like I could take apart the laptop as long as I had guidance. I've done it in the past to desktops but for some reason the bottom of my laptop is being stubborn. I think I located where the RAM should be, but it's under where my battery is held and I cant' remove the piece that divides the battery and RAM stick...if anyone had a diagram or steps i think I could do it...basically I'm trying to avoid taking it somewhere if I can to avoid it costing an arm and a leg...does anyone have a guess at how much this would cost to bring it somewhere like Best Buy or somewhere similar? And for that matter, what places besides Best Buy would do a repair like this?

    i'm jealous...it didn't work. I'm starting to think I'm going to have to bring it somewhere less someone can give me an in depth step by step to reseating my RAM. Anyone know roughly how much it might cost me to get it repaired by someone like Best Buy assuming it's not covered under warranty?

    well, considering that one of those places just charged a guy I know about $400 to swap a hard drive in his.... Depends on what's wrong with your laptop. I'd probably take it to a small PC repair shop and ask their opinion on it first. It is very hard to diagnose the problem remotely in your case, let alone help you get into the computer :)
