I can confirm that something similar is happening in my laptop (Acer Ferrari 3400). Here is a typical sequence in my case: 1. Power on with the AC adapter connected. ACPI correctly says that the adapter is on. 2. Unplug the AC adapter: The battery reading reports a discharging state for a few seconds (as expected) but soon it gets stuck in a particular value. 3. The battery may die, the laptop would then automatically shut down, but ACPI would never notice. I'm running the kernel 2.6.10 with AMD64 support, straight from kernel.org, with no vendor patches. So, this is not just an issue for the HP Pavillon computer. -- Pedro On Sun, 2005-01-02 at 21:44 +0000, Matthew East wrote: > I have now submitted a bug report on this issue, but so far haven't > had any bites either from my original message to this list or the bug > report, so I thought I would try again and see if someone has any > advice for me. > > Many thanks, Matt > > ---------- Forwarded message ---------- > From: Matthew East <mat...@gm...> > Date: Wed, 29 Dec 2004 11:11:36 +0000 > Subject: battery state on Compaq Presario > To: acp...@li... > > > Hi there, > > Since 2.6.9 kernel I have experienced problems with the battery state > on my Compaq Presario 2104EA laptop.
