As TM5520, classfied into hardware & software : 1.Software : Vista or VistaSP1 & Acer's empowering 2.My Config : TL-58,ATI 2400 , 3 G ram ( over 6 months )
From beginning , just use Vista ,not XP, so not talking "XP" ,Due to Vista,so many complaining so updated to SP1,after changed new M/B & SP1, everything is fine,except Adobe Photoshop CS3.... ( Licensed ? )
suggesting to updated to SP1,if you have same problems, it is something to do with your M/B ,it was same problems for me , 無法進入睡眠 , 進入休眠 , 無法開機 , 電腦無法關機.......... 最後無法開機 . first trouble shooting , I thought Vista's problems , ...................... but It is my M/B .
At the time being, Vista home premium with ATI 2400 , high resolution ,offer good entertainment ,so no desire to change to "XP"
Suggesting send to Acer service, it is a good idea , From my points ,it is offer very good service .
