ActiveSync atau Windows Mobile Device Center Gagal Terkoneksi

Saturday 5 February 2011 | Comments (4)

Postingan untuk dokumentasi pribadi :razz:

6520Hal ini terjadi pada Samsung Omnia Pro 5 B6520 (Windows Mobile) saya. Setelah habis di-oprek-oprek tiba-tiba device ngambek tidak bisa terhubung via Windows Mobile Device Center (OS Win7). Sementara, anomali terjadi jika menggunakan Activesync (OS WinXP), device tetap terhubung dengan baik.

Btw biar kata smartphone dengan OS WinMo 6 ini terbilang lawas ( bahkan ditinggalkan developernya :roll: ), fitur didalamnya masih sangat ajib dan mengikuti perkembangan zaman (WiFi – 3G – Qwerty – GPS). pengen ngikut ngandroid yg lagi ngetrend, berhubung duidnya ga kesampaian, terlebih-lebih ngarep make iPhone.

A little review from me. Well, seems you must buy USB to VGA peripheral to connect this netbook to a projector. If you weren’t familiar with Windows CE OS, maybe it’s difficult to add some desktop application, or becoming an open source revolusiner by using Android OS (yai). The small storage and memory device must be considered since this netbook general purpose for office and browse internet. You can upgrade it by buying another bigger peripheral.

Jangan Beli Axioo Neon MLC-2222, Jika Anda Pengguna Linux

Atas rekomendasi saya dan temen saya, saya menyuruh teman saya yg lain untuk membeli Axioo. Pertimbangannya, after salesnya Axioo bagus dan barang juga tidak begitu mengecewakan, walau brand-nya tidak sekuat Dell atau HP (sory, Toshiba gw kagak maen). Sebenarnya bagus atau tidak after salesnya relatif juga, berhubung saya di Jakarta, dan pemerintah kita masih picik soal pemerataan pembangunan (terlihat dari kebijakan mobil dinasnya). Mungkin saja stok spare part di sini sangat mudah, ketimbang di daerah2 yang musti indent dulu beberapa selang waktu.

Extending Battery Duration on Ubuntu Jaunty

Thursday 20 August 2009 | Comments (9)

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.
