Hi, i have a sony vaio fx140, and a week ago it shut down unexpectedly, then i restarted it after turning it off for a while and it worked, but now it doesn't. it only starts in safe mode but only with the battery (without the plug), if i use the plug it gives me a dialog box asking to restart normally, safe mode, safe mode networking, etc. If a choose start normally, it tries to run windows, but then the screen goes blank, the power light is on, i hear the computer running ( i think) but nothing happens. If i use the battery to restart normally, it can't do it. If anyone has any idea what this could be, please let me know. thank you in advance for your time!. eugeia.
