    Hello Everyone,

    This is my second post so please bear with me.
    Skip the first three paragraphs if you don't have time.


    I bought a T61p in jan-2008. I have sent this thinkpad to service centers for repair a couple of times, once for replacing the motherboard( the bios updater screwedup) and the other time for a broken LCD hinge. The service was excellent (they even sent me spare parts a couple of times like keyboard, touchpad etc).

    A few months ago i spilled some beer on the keyboard, so immediately switched it off, opened the laptop and carefully cleaned everything. Switched it on, TADA it works as good as before.

    A couple of months back i realized my warranty is about to expire so i though i would send the system for a final checkup. Now the guys at the service center tell me that there is a spill and to repair it i need accidental coverage which i don't have and cannot buy after the "accident". To repair it they asked for an advance of $800 - the laptop costs around 1400, it seemed to me that the cost of repair was too high. So they send me back my machine.



    Now when i switch on my machine, i can see that the screen is active (if i look it at an angle i can see even different colors) but it is almost pitch black. I did some research, bought an inverter and lcd connection cords from lenovo and replaced the old one, no difference. Thought it must be the CCFL lamp, so bought a new lcd screen and replaced the existing one, still no difference. Frustrated, i removed the whole lcd from the hinge and connected my machine to an external monitor, this works perfectly.

    My Question: Where is the problem, i replaced lcd, inverter, the connector cords. If there is problem with the graphics card the external monitor shouldn't work(i can even play games on it). Is there anything that can be done (a laptop is better than a converted desktop). Please share your expert thoughts, opinions and comments.

    Thanks,
    Elliot

    since you have replaced the LCD, inverter, cable, etc. Then it suggests the problem is somewhere on your motherboard, also you mentioned spilling some beer, which would usually cause corrosion on the motherboard.

    Your only option is to actually change the motherboard, but i don't know whether this is a worthwhile fix given many aftermarket T61p could have a faulty nvidia GPU, so there is a good chance of you getting a lemon.
