Hello
Encounter a strange problem:
hardware is asus eeepc 900 netbook ( celeron 900 mhz, 1 Gb RAM, 16 Gb ssd on ide (internal).
have installed slackware 13.1 on second partition of ssd, and when i close lid, it go to suspend to ram, when i open lid and touch a Fn or F1 key, it wakes up. it all work very good without any problems.
some time ago i purchase 2GB RAM module, and swap (that machine supports max 2 gb, and have only one memory slot). all works without any problems ( until yesterday i do not put netbook to sleep ), but yesterday i close lid -and netbook going to sleep, as always.

but when i open lid and touch a key, "on" and blue "wifi" led switch on, but nothing another changes - screen is absolute black, any indicators not activity, short press on "on / off" switch do nothing. also touching any keys do nothing. i try it many times - always get the same. after that i turn it off only if long press off button - then netbook switched off.
