Samsung NC10, a 6 cell battery & Windows 7

samsung-nc10-battery I’ve had my NC10 for a few days now and you can read about some of the things I've done to maintain the battery runtime XP delivered, but with Windows 7 in my previous posts.

I got my 6-cell batter delivered and wanted to let you guys know how I got on. With the three cell battery I managed to reproduce XP’s 2.5 hour life on Windows 7 after a bit poking around with services and drivers etc.

I charged up the new battery and run it from fully charged, just browsing the web. until it switched itself off. 7.25 hours it lasted. I was impressed. This battery had not been conditioned properly and it was already producing comparable run times to the advertised life.

The interesting thing here is that the batter life achieved with a 3-cell battery is not anywhere near half of what you get with a 6-cell battery. I’m sure there’ll be a scientific explanation about why this is, due to load sharing etc, but for now, I’m just happy that I’ve got a very portable machine that can last a full work day.

One other thing I wasn’t expecting was the battery sticks out of the case at the bottom. I wasn’t expecting this, as people only talk about how much the 9-cell battery sticks out of the body. Perhaps this is because most NC10’s come with a 6-Cell battery in the first place.

I can’t think of any other interesting things to say about my NC10, so this may be my last post about it. Well at least until Google Chrome OS is released :-).

Convert Linked Mailboxes to User Mailboxes in Bulk

My organisation has gone through a massive migration project to unify Active Directories and Exchange organisations. As a result of these migrations a lot of mailbox migrations have resulted in a lot of mailboxes ending up as linked mailboxes even though their not.The official TechNet article on this explains how to disconnect the mailbox and re-attach it to the user account correctly as a user mailbox. http://technet.microsoft.com/en-us/library/bb201749(EXCHG.80).aspxAnother way to make this appear to be corrected is to manually change the “Recipient Type” AD property on the affected mailboxes. This though, is unsupported.Using the official method from Microsoft results in the loss of any specific mailbox information such as SMTP, x400 & x500 addresses, mailbox sizes and any other individual mailbox settings.Only e-mail addresses and mailbox sizes were important to me (I must admit, I forgot about mailbox sizes at first). I came up with the script below that would properly conver…

Creating a Windows PE 3 Bootable USB device

I’ve used Windows PE for a long time. And I’ve grown to love it. It’s an extremely useful tool, not just for OS installation, but for diagnostics.Since there’s a version of WinPe for x64 & x86 (& itanium) I like to keep both x64 & x86 on my USB stick. Essentially copying the each version to the root of the USB stick as needed. Meaning at any one time I have three copies of WinPE on my USB stick. Other applications I copy directly to my USB stick, so that I don’t have to remount the image every time i need another application added.Shortly after Windows 7 was released came a new version of WinPE, WinPE 3.0 on the Windows Automated Installation Kit.Preparing the USB stick. You’ll need to prepare the USB stick. To do this open a command prompt using Run As Administrator and use the following commands.diskpart
list disk
select disk 7
clean
create partition primary
select partition 1
active
format quick fs=fat32
assign
exitMake sure…

Upgrading Exchange 2007 Clusters to SP2 – Workaround

I posted last month about a problem delegating installs of Exchange 2007 SP2. Delegated Admins will receive an error message stating the following…You must be a member of the 'Exchange Organization Administrators' or 'Enterprise Administrators' group to continue.Have been looking into the issue and have had a case open with Microsoft. Turns out that you only get this issue on a fully patched server. If you try upgrading or installing as a delegated admin on a fresh install of either server 2008 or 2003 you don’t see the problem either with Exchange SP1 or SP2. I haven’t had time to identify exactly what patch causes this yet, if I’ll bother at all.If you have patched your server though, MS came up with this workaround.Disable update checking for the BPA by heading into the registry and HKCU\Software\Microsoft\Exchange\ExBPA and either creating or modifying a DWORD named “VersionCheckAlways” and set it to ‘0’Copy the installation files to a local drive and replace Setup…
