Bug Description
I have an HP tx2510.
Following instructions on
http://
(which do work on another laptop), it doesn't wake up from sleep.
After giving the commands:
echo 0 > /sys/class/
echo `date '+%s' -d '+ 200 minutes'` > /sys/class/
I can see with
cat /proc/driver/rtc
that the wakeup seems to be set correctly. But I tried to wait a lot of time (6 hours: notice my local time differs only 1 hour from UTC) and it never wakes up.
Notice that:
- in the BIOS there is no option to enable/disable it, but it does work from Windows Vista. In particular, I tried all the programs from http://
- after (the acpi wakeup didn't work and) I manually wake up the computer, in the output of "cat /proc/driver/rtc" I can see that
alrm_date : 2008-12-11
has become
alrm_date : ****-**-**
(while the time line stays unchanged). This is also what happens when I set an alarm in the past, so it seems to me OK.
uname -a says
Linux vousci 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:06 UTC 2008 x86_64 GNU/Linux
I'm attaching the output of "sudo demidecode".
