HPFOCUS

My 8570w has a strange problem these days. Windows in Ms-windows and Linux lost windows focus accidently. For example, mouse sticks on window A for several minutes. Window A lost its focus. The window title becomes grey. No response as I click mouse left button. but move to window B, everything ok. The problem randomly occurs in window a or window b... Fixing such problem around is pressing alt-del-control, clicking cancel button.

I doubt the video card ASPM has problem. Turn off the ASPM in kernel but problem is not fixed. I also doubt the CPU, motherboard, even led light in my room. Today I disassemble this laptop to replace video card. I found the touch pad connector was damaged. Tear out the touchpad connector, problem is fixed.

I'm sorry in typing in English since the laptop operation system was reinstalled for troubleshoot. The new win7 can not install Simple Chinese patch report system error. It is bad.

更新下BIOS，重装下系统，选择最新的驱动，看看有无改善

已经好了，拆掉触摸板。原因是触摸板排线接触不良，导致故障现象很奇怪。窗口焦点一下有一下没有。鼠标左键有时不反应，很像软件问题，但换不同类型操作系统故障依旧。
