14 You don't provide a lot of details. The first thing you should confirm
15 is whether or not the laptop is actually locking up or just some process
16 (like X) is using 100% cpu. To check this you can try a couple of
17 things:
18
19 1) try to access the laptop from a remote computer. Of course, make sure
20 you can access the machine remotely before the machine locks up. I
21 normally have ssh running on my machines, but you could use telnet, rsh
22 or possibly ftp or http. Just make sure you have the appropriate service
23 running on the laptop.
24
25 2) Use <CTRL>+<ALT>+<F1> to try and switch from X to a virtual console
26 window.
27
28 3) If you have ACPI properly setup and responding to the power button,
29 you could try pressing the power button < 3 seconds. This should shut
30 down the laptop.
31
32 If any of these above work when the screen is blank, than the system is
33 not locked up. It's likely X or some application is causing X to stop
34 responding. If this is the case, you need to figure out what is causing
35 the problem. The first thing would be to log in (either through VC or
36 ssh) and run the "top" command. This will show what the system is doing
37 and how much CPU time each process is using. What to do from here
38 depends on whether or not something is using 100% CPU.
39
40 If you can not log in or shutdown, then it's possible the machine
41 did lock up. Then next steps would be to look in the logs (/var/log) for
42 any clues to what may be happening before the system crashes.
43
44
45 Is this a new install on new hardware, or was it working fine and just
46 started locking up?
47
48 It may also be a heat problem. You may want to look in to getting
49 lm_sensors or some other tool installed to monitor the system
50 temperatures. If could be the CPU or GPU is over heating and either
51 stops responding or shuts the system down.
