    I have a Sony Vaio model PCG-4A1L notebook computer. Today when I went to power up absolutely nothing happened. The power lights are on but nothing is operating. I removed the battery and tried to run it off of AC power and also unplugged the AC and tried to run it off of battery power. Still nothing. I went to Sony's website and they didn't even recognize the model number. Any help would be appreciated.

    Thank you.

    Hi there :cool:,

    I have a few questions, answers to which will help figure out what the problem is.

    When you turn on your computer does your screen turn a different shade of black as if power is running through it or does nothing at all happen on the screen?

    If you put your ear up to the machine can you hear something like a cd being read? Note the sound is different to a fan being on. This is to tell if your harddrive is spinning.

    I have solved this problem before by replacing the RAM. If you have two RAM modules installed, try switching their spots, or only using one at a time in different slots. If it is faulty RAM (if switching them worked) you'll have to test the modules with a program such as memtest or any other boottime tester (or the Universal Boot CD) and replace the one that is faulty.

    Other possibilities are a blown LCD inverter, which needs to be replaced by a technician but is inexpensive, or there might be something wrong on the motherboard/onboardvideo/videocard all of which require expensive repairs in which case it might be cheaper to buy a new system. (that is... if you dont have warranty on the system... but you wouldn't be here if that was the case.)

    There is no noise whatsoever. The green power light is lit and the battery light is lit. When I push the power button nothing happens at all.

    Have you a monitor you can connect externally? It sounds like the main board has gone south, but maybe an external monitor may show something. Probably not, but it may be worth a shot.

    I can try to connect an exterior monitor. I think I have what I need.

    Have you tried my suggestion about switching out the RAM sticks?
