This Sony Vaio PCG-K23 over the last year would have good days and bad days. Sometimes it would boot up on the first or second start. Other days, it would take 20-30 starts to get it to boot. Other days it won't boot at all. When I say boot, I mean the monitor powers on and the logo appears.

If it makes it that far, it's usually good to go. The XP operating system never crashes and in that respect, it's very reliable. Getting back to the boot problem, on several occasions it will hang at the logo and you will not be able to enter the bios. When this happens, I remove the cmos battery, wait a while, and reboot.

Whether or not that has any direct effect other than clearing out the bios settings is difficult to figure out because this isn't an instant fix. Sometimes it takes another 20 times or an hour warm up period before it will start normally again. Another clue is that if you're shutting down Windows with a 'restart,' 99.9% of the time it will restart perfectly. There has only been two occasions over the past year where the monitor would not power up after a restart. What happens presently when the power button is pressed is the power led comes on and the three green led's blink on and off (for caps lock, num lock, and scroll lock) the yellow power light comes on, and that's about it. If left on for a while, the internal fans will crank up to a normal operating speed. I am wondering if the startup circuit in the monitor is flaky.

Of course the only way I would know if it were booting up without being able to see a display would be to see the hard drive activity light blinking and that doesn't happen when it doesn't boot. I've had the mother board out of the case more times than I can remember looking for cold solder joints, loose sockets, or anything that would point to this kind of trouble. I also removed the dvd drive and modem board to try and limit some of the hardware affecting the start.

That doesn't seem to matter either. I've tried different ram sticks but that doesn't make any difference. This last time it came on, the bios was reading only one stick of ram and despite this, XP still ran smoothly. I have two 512mb sticks installed. This problem is more seldom but it has mysteriously cleared itself up over time.

I've seen motherboards for sale on ebay but I hesitate to replace it if I really can't pinpoint the trouble. I'd really like to replace the bios chip but it's not a plug-in type and who knows if it's even available or if it would even correct the problem. And finally, it doesn't matter whether you use the AC power supply (which is the original) or run it from the battery. Thanks for any input you might have about this. This may be of no use to you at all, but I'll tell you anyway. I tried to upgrade my Vaios hard drive to a larger capacity model.
