Toshiba NB200 Netbook won't boot up

My Toshiba NB200 netbook freezes on BIOS splash screen. Looks like the netbook was shipped with a faulty motherboard. Unfortunately I can't do BIOS update as suggest in this post. Removing the Hard drive, RAM has no effect.

Am not ready to throw away the laptop. Wonder if anyone has a better solution.

Ubuntu On ARM : Changing Game Plan

My friend Tim Denny believes that ARM powered devices will drive the future of netbook and tablet computer technology. I agree with him, ARM delivers great performance and its low power usage makes it ideal. Perhaps the lightweight Ubuntu Netbook desktop would be a choice distribution for ARM powered devices.

The new release of Ubuntu 10.10 has all the right ingredients. There is better support for ARM, the Ubuntu netbook desktop is lightweight and Unity bring fresh design thinking for small screens. And now there is multi touch support as well. Here are some of the stories that that deal with this trend.

Ubuntu Gives Maverick a shot in the ARM

Excuse the dodgy pun but Ubuntu 10.10 is going to be a fantastic release for many reasons, not least of which is improved ARM architecture support.

Toshiba AC100 hacked to run Ubuntu 10.10 RC

The Toshiba AC100 is one of the first netbook-style devices to ship with Google Android installed. The operating system is typically installed on smartphones or tablets with touchscreen devices — not computers with keyboards and touchpads. The Toshiba AC100, on the other hand, looks like a netbook, with a 10 inch. 1024 x 600 pixel display, a keyboard and touchpad, and no touchscreen.

Is not it amazing when you see these power-sipping ARM processors running a powerful operating system so smooth? Here is an ARM processor, the Marvell Armada 510 running Ubuntu 10.04 Netbook Edition.

Unity and uTouch

One of the most exciting things about the Ubuntu 10.10 release has been the delivery of the Unity ‘shell’ in Ubuntu Netbook Edition. For the uninitiated, this delivers a very different user experience to that in the main desktop edition.

Ubuntu 10.10 Multi-touch

As many are aware, we released our maverick Maverick a few days ago. Part of what comes with Ubuntu 10.10 is the new uTouch stack.

Multitouch And Qt

Until recently, there has been no Multitouch stack for Linux. The great news is that the folks at Qt are very interested in getting Qt to work with uTouch.

Ralink Wireless support in Puppy Linux

Gecko Edubook
My Gecko Edubook has a Ralink wireless USB adapter. Later models of this ultra-cheap netbook shipped with more ubiquitous wireless cards from Realtech. You have to get the download the firmware and blacklist few modules to be able to use Ralinux wifi wireless card in puppy linux 5.1.

Download the firmware for RT28XX/RT30XX USB series (RT2870/RT2770/RT3572/RT3070) zip file and extract the rt2870.bin file to /lib/firmware.

Next use the BootManager configure bootup program to blacklist rt2800usb kernel module and enable rt2800sta module instead. These steps should enable Ralink usb wireless card support in puppylinux.

Acer Aspire One BIOS Reflashing

Few hours before flying out of Nepal the Acer Aspire One netbook died. The BIOS got screwed, netbook won't even complete Power On Self Test(POST). Competent computer hardware technicians I hear are as rare as the famed Himalayan Yeti. Wiping my tears and picking up the thousand pieces of shared ego from the floor, I set about reflashing the BIOS. Thankfully, the relief was quick.

How to reflash a Acer Aspire One BIOS

Please be careful, you might end up bricking your netbook. :)

  1. Download the latest BIOS and extract the v.3114.zipcontent to USB pendrive
  2. Rename the ZG5_3114.fd to 'ZG5IA32.FD'.
  3. Power on the netbook the with pendrive connected while holding down Fn + Esc keys. Make sure the power cable is attached.
  4. After a few seconds the power light blinks, press power button once and wait till the netbook reboots.
It took few minutes for new BIOS to be flashed and the computer automatically rebooted.

Acer Aspire One Battery Charging Problem

If you believe amnesia is a malady that effects humans, think again. Recently a Acer Aspire One netbook landed on my table with a similar problem. It refused to charge the battery, perhaps it always thinks the its battery already full. The only way you can use this machine was by connecting it the power outlet.

A quick search on the Internet will turn up a lot of Acer Aspire One (AOA) owners reporting similar problems. Quite often people update the Bios to fix this problem. However there is similar solution.

The Problem

The Amber (Orange) battery light blinks constantly and netbook works only on AC power.

The Solution

Follow the steps given below. (Please be careful when handling computer electrical components like batteries and AC Adapters)

  • Remove the battery and hold down the power button for few seconds (to drain all remaining power)
  • Power up the computer without the battery with the A/C adapter plugged in.
  • Wait for few seconds and plug the battery back in

After a few tries the computer should start charging normally. The amber battery stops blinking and turn green when fully charged.
