My dear Laptop, looking for new Owner :/

Update: SOLD
With heavy heart, I have decided to part with my 3 year old ultra portable, fun to have and absolute bliss to use laptop for travels (1.6 kgs only!).
We’re talking about ‘Shenron’ (Shenron, is the name of my laptop derived wish granting dragon of Dragon Ball Series;  Yes, I name my gadgets, problem? :D).

The Cheezy Stuff:

Shenron is an HP DM1-Z, which I bought jumping with joy when the AMD APU Fusion Zacate platform blasted performance without eating battery life was released, 3 years ago.

It was and is still the best 11.6 inch laptop available, other than well MacBook Air… or it probably beats air in few areas easily (unless if you’re an apple fanboy).

This is a special model of dm1-z, which is equipped with a 7200 rpm speed hard drive (no other models of dm1-z or even other 11.6 laptops came with 7200 rpm to reduce cost.) Even my new 14” laptop has only a 5400 rpm harddrive, imagine that! 🙂

What’s EXTRA for you!

I have a NEW original battery on this(the battery cover is still on), which I purchased for INR 6500 after the stock one died.

I have only discharged the battery to 10% less than 25-30 times and just for keeping it maintained or calibrated. So basically you have ton of life left on it. (Unless you don’t know how to maintain a laptop battery that is 😉 )

DM1 has been known for its long battery life. The 6 cell battery, 65 W adapter .. this has got juice to give you 9+ hr of idle backup time and usage time of about 5.5 hrs (I’ve tested this with both the stock and this new battery).

It also has a RAM upgrade by another 4GB stick, so that makes it a 6GB RAM fucking awesome machine! 🙂  [ Extra chargeable for the 4GB stick, read at bottom of the post ]

Also I am meticulous about stuff, so I maintained the laptop pretty well, including I’ve got it cleaned twice inside out for dust, cleaned heat sinks, the bridges, the keyboard, replaced thermal paste with new improved ones so that it contributes to cooler running and better throughput.

The Tech Specs:

With AMD APU E-350 Zacate, integrated ATI Radeon 6310M, 2GB 1333Mhz memory (one slot free to expand.. and can upto 8GB), 320GB HDD (7200 rpm), Altec Lansing speakers – Dolby Advanced Audio, HD LED HP BrightView display, this laptop was making waves when it came in.

And I haven’t still seen a 11.6” that comes close to this. 🙂

For buying my laptop, you get the new battery (so you’re not buying old battery which doesn’t have life left), and can opt to buy the extra 4GB of RAM at lower than market price from me. (Else I can totally use the extra ram on my new laptop)

Oh look, I love the almost 180 deg tilt!

 

Why I’m being cruel :

The laptop certainly didn’t deserve to go away from me so soon. I love it, it’s beautiful, thin, super portable and I’ve used it for my game design, made video games on it for almost 1.5 yrs now, running VMWare, Virtualbox, playing HD videos, playing games, editing videos.

I could still happily keep using it. It’s got the power I need, it feels very happy to carry around while travelling, and its got long battery life.

However, I have a new 14” laptop which I bought for one of my programmers and unfortunately we decided he should leave.

Now that leaves me with 2 laptops, and the new one has been lying in shelf. It has way less battery life (3 cell) when compared to the one I’m selling away. And keeping it in shelf means unused battery, means screwing it up.

The only +ve of it above this laptop is that it has 14” screen and I thought, for someone who writes games for a living I do need a bigger screen.

 

 

Shut Up and Take my money!

I am currently living in Hyderabad, India and I’m here still for the next 20 days.
So if you live here, or even if you live in another state but have the means to get this laptop to you (I’m not delivering/posting) and want this baby to be yours, then do email me at
das (dot) srikrishna (at) gmail (dot) com
You’ll have to give me 2 days time to back up my data to the other machine. I’m still using this, and infact writing this blog post from it.

It came preloaded with Win 7 home, but I’ve used Linux on it for 2.5 yrs and using Windows 8.1 since 0.5 yrs.
I can either install ubuntu linux for you or give you without OS (since the windows 8.1 is licensed to my company), however if you have a windows 7, you can happily use the product key which is written underneath the battery compartment… so you have a genuine windows license. 🙂

I spent INR 26,000 on laptop, and INR 6500 on new battery, INR 500 for matt finish screen protector.
Monetarily that brings the price of this beautiful machine to INR 33,000
Not to forget tons of time for careful handling and love!

I’d like to let go of this lovely hardware for just INR 15,000 only. (that’s less price than your 10.1 inch slow netbooks of these days)

The extra stick of 4GB RAM, 1333 Mhz costed me INR 3100 which you can opt to buy for INR 2,200, if not I can give it away to someone else or just use it in my other laptop.

So there 🙂

Wi-Fi on HP dm1

Filed under: GNU/Linux — krish @ 8:56 am
Tags: , , , , , , , ,

Alright guys, so I got the HP dm1(AMD Fusion) and cancelled the Lenovo Thinkpad x120e that was ordered in US, for many strong reasons that I’ll blog up later.

The HP dm1 comes with Ralink wi-fi card which most of the current Linux distros do not identify out of the box as of now / end up probing the wrong driver.

This is how to get your wi-fi up on the hp dm1
(as well as other new laptops with Ralink cards; just get the correct driver that matches your card )
Note: This was done on Ubuntu 10.04 – 64bit

1. Update your distro. 10.04 needed update to newer kernel 2.6.30 and headers for drivers to compile
krish@shenron:~$ sudo apt-get upgrade

2. Check the model of your ralink card (Mine shows 539x series which is a Wi-Fi, Bluetooth Combo)
krish@shenron:~$ sudo lspci | grep -i 'network'
02:00.0 Network controller: RaLink Device 539f

3. Go to ralink website http://www.ralinktech.com -> Sofware -> Linux and Download the driver that matches your card version.

4. Unzip the package
krish@shenron:~/Downloads$ unzip 2010_1217_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO.zip

5. Change configuration
krish@shenron:~/Downloads$ cd 2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO/os/linux/

krish@shenron:~/Downloads/2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO/os/linux$ sed -i 's/HAS_ANTENNA_DIVERSITY_SUPPORT=n/HAS_ANTENNA_DIVERSITY_SUPPORT=y/' config.mk

krish@shenron:~/Downloads/2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO/os/linux$ grep ANTENNA_DIVERSITY config.mk
HAS_ANTENNA_DIVERSITY_SUPPORT=y
ifeq ($(HAS_ANTENNA_DIVERSITY_SUPPORT),y)

6. Build
krish@shenron:~/Downloads/2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO/os/linux$ cd ../../

krish@shenron:~/Downloads/2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO$ sudo make

7. Install if Step 6 was successful with no errors; else start fixing your config again 🙂
krish@shenron:~/Downloads/2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO$ sudo make install

8. Make your correct card number to be probed ( Use your card model here, mine is rt5390sta )
krish@shenron:~$ sudo echo "rt5390sta" >> /etc/modules

9. Blacklist wrongly probed ralink drivers – Ubuntu 10.04 probed this bluetooth module
krish@shenron:~$ sudo echo "blacklist rt2800pci" >> /etc/modprobe.d/blacklist.conf

10. Reboot
krish@shenron:~$ sudo shutdown -r now "Yay!"

11. After the machine is up again, check for ra0 interface
krish@shenron:~$ sudo ifconfig ra0 | head -n2
[sudo] password for krish:
ra0 Link encap:Ethernet HWaddr 90:00:4e:1a:76:e6
inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0

Wolah, you’re connected and free to move away from the computer table on to the couch for some lazy working style 😉
