Ini bukan postingan paid review 😮

Have you ever in this situation, you have a job who’s very urgent and need to be finished soon as possible? Your job is very related to computer, and you really need a reliable computer system to support your job. Suddenly, at that time, your computer went down and displaying a black screen with blinking underscore character on top, without CPU light activity.  Or sometimes, it displaying a blue screen with some alphabet character which you don’t understand about it at all.

Tidak Memakai Windows, Uang Anda Kembali.

Thursday 12 November 2009 | post a comment

Seseorang bernama Graeme Cobbett melakukan komplain kepada Microsoft. Dia meminta uang kembali kepada perusahaan atas lisensi sistem operasi Windows Vista yang tidak terpakai di notebook yang baru ia beli (satu paket terbundled di dalam). Sebagaimana kita ketahui sekarang ini, banyak laptop yang dijual rata-rata sudah dilengkapi dengan sistem operasi Windows. Graeme lebih memilih untuk memasang Linux Mint di laptopnya.

Extending Battery Duration on Ubuntu Jaunty

Thursday 20 August 2009 | post a comment

I admit that Ubuntu Jaunty running well on my Compaq CQ40-337TU, except a small problem for sound device (already fixed). All devices work properly, VGA with 3D effects, WiFi device, webcam, optical drive, synaptic pointer, etc. But I notice one thing, the battery consumption with Jaunty is very bad.

I search in “Mbah Google” about this problem, and found many solution to extending battery life duration.

  • Adjust your desktop appearance without sophisticated effect (include 3d effect, which also have a same problem on Vista). This effect is cool, but it consuming too much electricity on VGA card.
  • Decreasing your display brightness into lowest level. I can still have a clear view on laptop LCD using the lowest level brightness.
  • Adjust CPU voltage into power save mode. If you hate to edit any script configuration, you can install kpowersave to easily adjust this configuration (monitor brightness also can be adjusted with this tools). Put kpowersave to always run when Ubuntu started first time.
  • Install powertop apps. This app will suggest you about the best way to lowering voltage consumption based on your hardware usage.

After doing those tweak, I got 3 hour battery life (before doing it, I only got 2 hour). Kpowersave and powertop are available on Ubuntu repository. Btw, Ubuntu has it default power management tools (gnome power manager), so I disabling it before installing kpowersave. I prefers to choose kpowersave since it had more integrated configuration setting.

I’m waiting for your response. Please give me another suggestion to tweak battery consumption on Linux, I still find another great way about doing this. Go green Indonesia.

HP Compaq Presario CQ40-337TU on Ubuntu 9.04 (2)

Friday 3 July 2009 | post a comment

This the update information of my previous post. Overall, I feel satisfied with Ubuntu Jaunty on my CQ40-337TU. The 3D desktop running smoothly and sophisticated. All device work well, such Wi-Fi, optical drive, and webcam.

But, there is other problem which is very annoying. I read the manual about my laptop. It’s say that the battery life can reach about 4 hours 15 minutes. When I’m running Ubuntu on it, battery life can only reach about 2 hours (using 3D desktop effect, browsing activity, and USB wire modem attached).

I’ve try tweaking the power consumption. First, I adjusting display brightness into lowest level. Then, switch the processor volt into power save mode. I also turn of the desktop effect (same problem with Vista on Aero mode) and WiFi device. And I got about 3 hours.

Where’s another 1 hour? Any suggest for my laptop, or should I back to Vista the P1r4t3s 3d1t1on?

HP Compaq Presario CQ40-337TU on Ubuntu 9.04

Saturday 27 June 2009 | post a comment

On computer exhibition in Jakarta (Pekan Raya Jakarta 2009), about 5 days ago (23 June 2009), I was buying a notebook. I buy a CQ series of HP-Compaq, the Presario CQ40-337TU exactly. I choose this type because it’s have a balance between the price (540$) and the quality (HP-COMPACT).

I have a plan to install dual OS (XP and Linux) on it. But, I’m facing some problem. When installing XP, the installer can not found my HDD device ( I think it’s using the AHCI mode). I check my driver CD, and it’s only provide driver for VISTA. The official site also didn’t provide the driver for XP.
