Notes

The computer might lock up, especially if running heavy applications or stuffing the air duct. The ACPI support is rudimentary, linux can barely read temperature and it is not clear whether it is even correct (it is not changing when CPU is overloaded).

Note2: The fact that the hard disk can not be replaced without voiding your warranty or visiting Dell service center might complicate laptop replacement and disappoint some Linux users.
