整个屏幕还亮，就是没有任何反应，风扇还转。
原来以为风扇脏了，清洁后，不行；又以为导热不好，涂了新的AS-5，也不行....最后，随手喷气体冷却剂到GPU，就能运行。但总不能永远这样敞胸露怀的物理降温呀。没办法。

我的是显示器的灯管问题


T40的话可能问题不一样

因为T40很有可能是显卡虚焊的问题，你电脑挂的时候，系统还在工作吗？ 还是连系统，硬盘都挂了？


给你一个论坛，你搜索看看就知道了

thanks for the website you recommended. i just found sth probably useful for my t40:
--------------------------------------------
I just almost fixed my T40 with a loose GPU.

The trick is to get something stocked between the GPU and the keyboard. So when you tighten the keyboard screws under the trackpoint buttons it will make a firm pressure on the GPU.

I added a little aluminum cooling profile on the GPU - and fixed it with some cooling paste. On top of that I added enough post-it stickers to make the pressure on the GPU when then keyboard is back on.

So far it works.
