求助：关于系统待机的问题
t23，2003年5月买的，安装的winXp pro
休眠功能（按Fn+F12）一直用的很好，节约了不少开关机时间。但是从上周开始，待机后再启动，就会到最后本该出现用户登陆界面的地方变成一片黑暗，整个键盘其他按键都无效，只有power键还工作，以及Fn+PgUp开小灯的功能还有用。于是只好强行关闭再正常启动使用。
待机功能（Fn+F4）一直都不好用，我每次只要在正常运行状态时候按一下键盘右上角Insert键上方那个小按钮，或者按Fn+F4，系统提示“准备待机”，然后屏幕黑掉，键盘右上方指示灯那个小月亮亮起来。此时再按Insert键或者Fn+F4，可以听到光驱有一下反应，然后就没有任何反应了。此时显示器漆黑一片，整个键盘其他按键都无效，只有power键还工作，以及Fn+PgUp开小灯的功能还有用。于是只好强行关闭再正常启动使用。
Fn+F3的关闭显示器功能倒是一直都很正常。
bios曾经刷成1.17 版本，还是没有解决该问题。于今天将bios刷成1.18版本，解决了以上问题待机后和休眠后可以醒过来了。查看1.18的说明，发现就是专门针对待机后系统挂起问题的。不过刷新bios后系统出现一个新问题，就是挂起系统后再回来，windows系统就会变得不稳定，且无法进入休眠了。
