Punca keyboard laptop rosak

Jika kerosakan keyboard laptop boleh dilihat dengan mata kasar seperti salah satu butang tercabut biasanya berpunca daripada kelalaian kita sendiri seperti membiarkan anak kecil bermain dengannya.
Akan tetapi, kerosakan keyboard yang tidak boleh dilihat dengan mata kasar inilah yang sentiasa menjadi tanda tanya kebanyakan pengguna. Apakah punca secara tiba-tiba salah satu butang tidak berfungsi?
Tiga punca kerosakan keyboard laptop berdasarkan pengalaman kami ialah:
  1. Bermain permainan komputer dengan menggunakan keyboard laptop. Tidak kiralah permainan komputer jenis apa pun kerana semuanya akan melibatkan emosi dan secara tidak sengaja kita akan menekan butang keyboard juga dengan penuh emosi sehingga menyebabkan kerosakan. Jika ingin bermain game boleh bunakan external keyboard yang murah sebagai pencegahan.
  2. Biasa juga terjadi ialah air tertumpah atas laptop. Walaupun laptop telah dibiarkan kering untuk seketika tetapi litar elektronik di keyboard mungkin tidak terselamat kerana tempat mula-mula akan terkena apabila air tertumpah atas laptop ialah papan kekunci. JIka anda mahu mencegahnya boleh cuba pasang pelindung keyboard (keyboard protector) yang berupa getah lembut.
  3. Laptop yang terlampau panas juga boleh mengakibatkan kerosakan keyboard seperti yang pernah terjadi kepada seorang pelanggan kami. Panas melampau ini boleh jadi akibat pengedaran haba yang tidak baik seperti habuk banyak di kipas processor atau memang processor dan motherboard itu ada masalah seperti kebanyakan laptop yang guna AMD. Untuk pencegahan anda boleh guna Cooler Pad.

FLUX for UBUNTU

F.

F.lux for Ubuntu is an indicator applet (like the new Messaging Menu), so it works very nicely on Ubuntu 10.04 and 10.10. Michael improved the commandline application by leaps and bounds. There are a bunch of new configuration options (all available in the GUI), the night/daytime cycle is now much more accurate, and it even takes daylight savings into account.F.lux is a small but very useful application: It fades your screens to a warmer color temperature in the evening. This is pleasant for your eyes and won’t leave you wide awake at 2am because your computer monitors are so bright. There are mac and windows versions, but only a commandline app for Linux. Together with Michael Herf, the author of F.lux, I made a version for Ubuntu.
The F.lux indicator applet automatically manages the color temperature of your screen based on your latitude and longitude, or if you are in the US, your zipcode. In the preferences panel, you can set your preferred nighttime colortemperature and see a preview, as well as seeing the current color temperature.

Installation

Installation is easily done by adding the PPA for f.lux, simply type the following into your terminal:
  1. sudo add-apt-repository ppa:kilian/f.lux
  2. sudo apt-get update
  3. sudo apt-get install fluxgui
When you first launch the application (via ‘accessories’ in the menu, or by pressing alt+f2 and opening “fluxgui”) you will be asked to fill in either your latitude and langitude, or your zipcode. If you want f.lux to autostart at the next startup, select the “autostart” option. Close the preferences panel and you’re all set!
There is a bug in the current version of Fluxgui that’s preventing it from running correctly the first time it’s started. I wrote a fix that’ll be available in the PPA shortly (version 1.1.4). If you can’t start because fluxgui claims it’s already running, remove “fluxgui.pid” from the /tmp folder. After the update, it should work as advertised!

On Developing F.Lux For Ubuntu

As I mentioned, F.lux for Ubuntu is built using GTK+. This isn’t by choice, but needed because I wanted to built an indicator applet.
Coming from Python + Qt (for Trimage) , GTK+ feels like a serious step back. The Glade interface builder is clunky and quirky, and surprisingly, modules such as python-gconf and python-appindicator are virtually undocumented. There is a massive amount of time spent on figuring out what-goes-where-and-how.
Nevertheless, I like Python more each time I use it, and going back to JavaScript often feels weird (“Oh, yes, parentheses!”) so I think it’s time to start doing more with Coffeescript in the future.

Official Announcement

Michael posted an official announcement on the F.lux website with these instructions as well: f.lux for linux, so be sure to go there and leave nice comments for us and tell us what we can improve! :)

Future Versions

The currently released version is 1.1.1, For version 1.2 we will be adding a “pause for an hour” function, as well as an indication of how long until sunset/sunrise. Feel free to suggest other new features or fork the project on Github. It’s build using Python and GTK+, and the GUI is MIT licenced.
