Some versions of the TravelMate 7720 come with a ATI graphics chip. This model does not have one so it wasn't tested.

The microphone input does not seem to work at the moment. Hopefully a future ALSA update will fix this problem.

BTW, one of the killer advantages of this laptop is if you open the HD compartment you will find a second bay for a SATA 2.5” drive!!I have two 160GB drives in mine with the original drive untouched and the second one has Debian on it. It does use more power, though so two hours on battery is a stretch. checking the box in power management/on battery for 'spin down hard drives when possible' helps.

I have been running Debian sid/squeeze for several months on an Aspire 7720 (same computer?) and have one very serious problem and a few minor ones. The worst is that the latest kernel - 2.6.32-?? and I think 2.6.31 as well has an ACPI problem. The thermal zone for the processor is not accurate. It leaves a bogus 0c or 40c value in /proc/acpi/thermal_zone/TZ01/temperature. This keeps the fan from coming on and the processor overheats quickly to the point of shutdown. If I 'suspend' and reactivate, it starts putting accurate information into the file mentioned above. I have been unable to find any bug reports or even comments about this critical bug. As to the minor bugs, suspend sometimes (seems random so far) will blank the screen and not recover. I can blindly reboot the computer so it is still alive, but even the tty screens are blank.
The other bugs are very minor and not worth mentioning here. The ACPI bug needs to be addressed by someone with more programming skills and time than me.

Tom~the BIOS dsdt does not describe the fan; that is, the fan description is missing so when the kernel boots, it doesn't know where to talk to it to control it. This still has not been corrected as of V1.45 of the BIOS.

The fan turns on when the machine is powered up, and runs until the boot process transfers control from the BIOS to whatever is next. The fan normally stops running at that point, but if the machine was within a certain temperature range, it will continue to run, allowing the machine to operate normally. If the fan stops, it will run until the processor reaches its critical temp at which time it shuts down. You can confirm this is the problem, as the keyboard becomes quite warm to the touch in the vicinity of the “F” and “V” keys: right over the processor on the motherboard.

So far I have not found a solution, which ideally would be for Acer to correct the BIOS, or for a rewritten DSDT.DSL file that included a fan description (device PNP0C0B).

Due to two hard discs (one windows Vista , one Linux) I run until very hot, then Linux starts fan and is ok. Thanks for comments I appreciate the reason being stated. I have two of these I want to turn over to OpenSuse full time but now it seems they will always have the fan problem. They work well on OpenSuse 13.2
