Common symptoms and solutions for laptop overheating.

One day, Ah Beng tried to turn on his lovely laptop, intended to kick start his multimillion worth business project. After pressing the Power Button on the laptop, as usual CPU starts spinning. Suddenly, after a noise, "tug", the whole machine shut down by itself.

He tried very hard to start up the laptop by pressing the power button again and again, but failed. Frustrated, he brought the laptop to a service centre. Ah Siao attended to him, with his monotone, he gave the standard answer to Ah Beng, "Diagnose charge 80 dollars.. It could be mainboard problem, you might need to change laptop mainboard. "

In Ah Beng's mind, some questions surfaced, "How much damage to my pocket if i change laptop mainboard? ". "How long the service centre takes to repair my laptop?". "!@#$%^&**, i used the laptop not more that once a month, but it still failed!!"

Have you ever experience the disaster as  what Ah Beng experienced? Do you know that overheating could be one of the reasons, and the culprit could be just "DUST"??? Yes, it's just dust. I ever helped my friend to save his laptop by just cleaning the air vents. However, below is the in depth steps to clean your CPU heat sink fan unit for Compaq / HP Series.

中文版：笔记本过于热的征兆及解决方针

某天，阿明要拿他心爱的笔记本来从事重要的工作。他轻轻地启动他的笔记本。忽然间，他听见一小声“嗒”，然后整个笔记本无端端就关机了。

他无数次地重新再启动电脑，可是那笔记本怎么也动不了。在百般无奈之下，他只好拿他笔记本去电脑店修理。店员阿萧看了看他的笔记本，一贯地告诉阿明，“诊断费80新币。这也许是母板的问题，你也许得给它换母板”。

阿明愣呆了。心想“天啊，若真的要换母板那就很大花费了。况且这维修店要花多久才帮我修好？”“去他的！我这笔记本才用不到一个月，就不行了！”

你有过和阿明相同的经验吗？你没有意识到其实这也许只是电脑过热而已。而且也只是灰尘造成的问题。是的，你没看错，只是灰尘造成的小问题。我曾经帮朋友修理过有着一样问题的笔记本。我只是打开他的笔记本，清理一下排气孔，问题就解决了。根本不需要白花80新币去诊断而再花几百块钱去换母板。

以上是本人建议清理笔记本排气孔的步骤（Compaq / HP Series）
