i have had a few problemes after i bought my sony vaio laptop but this one is the worse and lucky me i didn't get the extended warrenty because of lack of money. I find it funny that this happened so close to my birth day the problem happened a few days ago i was trying to get the password prompt to not show up and i know thats not what made the problem because i restarted a couple of times. i was not running on my battery i was hooked into the wall. but anyway i left it on and went to have a smoke and what do i find when i came back, the computer was off. i thought no biggy and i pushed the power button. hmmm nothing came up at all. i made shure every thing was hooked up (on the outside, i wouln't think something would be unpluged on the inside seeing as i never go in there nor does anyone eles) So i take my laptop to my class computer repair for the teacher to check it out. he had no clue. i dont think that its the hard drive but i'm not totally sure. the motherboard doesn't seem to get power. but i came here to make sure because i dont want to send it to sony corp. unless i really have to. if you got any ideas please reply thanx, oi attack

Did u try to slap it few time?

try to press the power button for 10 seconds or so.... or try to unplug it and remove the battery over night...also check if your AC addapter is working regards Miro

If you are getting absolutely nothing, no lights beeps or whistles, I'd say the internat power supply is bad. Miro . . . even if the AC adapter is bad, unless the battery is stone dead it should do something eh?

If the AC is bad and the computer went into hybernation because of low batery, it will not wake up until connected to a working powersource. Depends from the batery condition you can get a short blip of light on the power lcd. The other posibility, but much less likely(happened on my very old notebook) is that the battery is very old and cant be recharged anyomore. Then it can take all the power from the AC adapter. you would notice that it is getting very warm if plugged in. Then there is not enough power for the computer itself. You can try to remove the batery and to run it only on the AC addapter. Dont do it for long time, the DC from the adapter is not clean and it is not intended to be used without the battery. If the computer works and is still worth more than a new battery then get a new battery, if it is less worth then a new battery get a new computer (that was my case...lol) Regards Miro

either the power supply and battery are cooked or the cpu has committed hari kiri.

i tryed it one the ac and the battery and the battery was fully recharged
