I have a Latitude 600 and when I turn it on, it may take up to 10 minutes or not at all. It will only stay on about 10 minutes or so then has a message saying preparing standby in order to eject.... The battery died just before this started happening. I have been in contact with Dell support 3 times...one said hard drive dying, another said motherboard, another said power supply...so which is it? I tried to do the test by pressing Fn and the power button but that does not work. I doubt this old thing is worth putting a new motherboard. I was also advised to never try working on a laptop myself..is it really that bad? Thanks
