To ajkula66,
I have not tested using external monitor.
The problem is a bit complicate:
There are actually 4 phenomenons:
1.
Sometimes, it can even enter the system while the screen is alwasys black since start. I have the fingerprint reader installed, and after I turn on or reboot my laptop for a while, I just swipe my fingerprint to allow enter into the windows system. And at this time, I can see nothing on the screen. But after I swiped my finger, I can hear the sound of entering the system. But I can see nothing on screen from the beginning to end.
2.
This happens much more frequently. After I turn on the laptop, the screen shows some vertical lines, and that's it. I can not see the "Thinkpad" logo. The brightness of the vertical lines may change sometime, but nothing else showed up.
3.
This just starts recently. After I turn on the laptop, I can see "Thinkpad" logo. But there're some black dots on the white letters "Thinkpad". And then when the screen shows the boot picture of windows xp, the screen also shows some weird color change in the XP logo. And before the system let me input the password, it starts to reboot. However, after reboot, the problem is still there.
4.
There's still a small chance that I can enter the system. Usually I have to turn off - turn on around 10 times or even more to get a chance to enter the system without problem.
Based on the experience 1 & 4, I think the parts of my computer (either Graphic card or motherboard) shoud be fine, or at least should work sometimes. Maybe it is not stable. But what I really think is the connection somewhere is kind of loose, and I just did not find it.
