ac adapter serious problem
hello unfortunately, i encountered a bad problem in my laptop (Dell Latitude D600) very frequent on these models: sometimes, the BIOS does not recognize the ac adapter and this seriously prevents the system performance: the CPU works at 600MHz (instead of 2000MHz); if the battery is not at 100% then the ac adapter cannot recharge it and so on... now, since the current can flow inside the pc i'd like to tell Debian to force the CPU working at full speed, without concerns about the adapter i post here this output since it may be helpful: ~$ cat /proc/acpi/processor/CPU0/power active state:C2 default state: C1 bus master activity: states: C1: promotion[C2] demotion[--] latency[000] usage[00198990] *C2: promotion[C3] demotion[C1] latency[050] usage[01315600] C3: promotion[--] demotion[C2] latency[050] usage[] thank you very much -- roberto OS: GNU/Linux, Debian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Please note that /proc/acpi/processor/CPU1/throttling would also be interesting for you. But still a bios upgrade would be the better solution.

This needs to be put on a complaint form over at consumeraffairs.com as soon as possible.
