Re: suspend/resume friendly laptop

Thanks, folks. I will write you more precisely, however, TP X61
running 6.99.43 suspends successfully. However, when I open the lid
again after a while, it doesn't resume well; the screen is black and
small underlined cursor appears in two locations. When I type
something on the keyboard, the characters displayed in two locations,
but nothing more. No command is accepted; No network is working.
I also guess that vesa mode is a suspect. I will let you know if
I got more detailed status.

The other purpose of my last posting was to know about laptop models
currently available in the market. Even if TP X61 works fine, nobody
can purchase it in brend new status any more. I'm also happy if recent
models such as TP X240 (I know Intel 7260 wireless is not supported at
this moment), Dell Latitude 14 5000 (Intel 7260 must be replaced with
Intel 6250, for example), HP ???, ASUS ???, ..., works well.
