  1. I have satellite L645, I have used it for year and suddenly comes out pop up message, system warning, about cooling system. Any solution to this? It's really annoying. Pop up repeatedly for many times.

    Your computer is telling you that it's hot and may need to shut down. If your computer continues to warn you that it's hot you will want to make cleaning out the dust a priority because the extra heat can break your computer.

    Well it seems that over the years your laptop has collected dust in the heat sink and fan and is now overheating or beginning to overheat. You can buy a can of compressed air, and while the computer is turned off you can shoot some of that air into the intake vents to see if the accumulated dust will come out of the exhaust vents.

    If your overheating condition doesn't improve, your second option would be to take your laptop apart and reuse the compressed air directly on the accumulated dust in the heat sink and fan. The second option isn't recommended for the inexperienced because you'll more than likely need a moderate level of skill to disassemble and reassemble the laptop, and you'll need to clean the processor of the old thermal paste, and reapply new thermal paste to the processor before you reattach its heat sink. :)

    All of those steps can be a bit scary for the first timer.

    most good computer shops will do a deep clean/system clean for around £25. or just £15 for dust clean.
