ACER Travelmate 6592 screen fault
Feb 23rd
Folks, I know I said I would blog more in the new year and I will but in the mean time I just wanted to share an interesting point about my laptop screen.
I have an ACER Travelmate 6592, the power supply blew for it last week and after buying what I thought was a genuine replacement only to find it was a dud, I now have the genuine part (from a different supplier). I have now started having issues with the back-light of the LCD display, it would hiss and flicker before dieing completely. I should say this problem occurred on both Windows vista & 7 and on Ubuntu Linux regardless of kernel version.
Thinking the un-clean power from the dodgie replacement power adapter may have damaged the back light bulb I was all for buying a new one and embarking on the daunting task of changing the back-light, until that is I discovered this blog post by Aral Balkan
Running the laptop on mains with the battery in causes screen flicker / black screen, where as running it with just mains or just battery it works fine.
I should also say that if you are running a laptop on mains all of the time you will shorten the life of your battery, therefore removing the battery from all laptops whilst running on mains for a long period of time is not necessarily a bad thing.
The only question is do I want to pay acer to repair my now out of warranty acer travelmate 6592?
Hope this helps some others out there and a massive thanks to Aral Balkan for his blog post.

Changing your password in Kerio Mailserver
Jun 16th
Changing your passwords is very easy.
Under your Windows computer press Crtl + Alt + Del and select change password.
To Change your email password, simply log into your Web Mail (call us if you don’t know the address)
Then Select change password from the Settings drop down menu as below
settings menu in kerio webmail
And then enter your old and new passwords in the box below.
kerio password change dialog box
Remember to make it something secure that no one will guess, no kids, partners or team names and no dictionary words. Random Numbers and letters, remember capitals and lower case combinations are best, or try a sentence like “Why can 1 never remember 555″ you can use spaces. Remember the best passwords are not necessarily easy to remember but they can be if your clever about it. Hackers offten use a dictionary or password list attack to crack passwords, this is where a system tires every word in the dictionary or in a common password list, things like Rangers, Rang3rs or Celtic, C3lt1c will be near the top of that list.
Security Bulletin – Adobe Reader and Acrobat
May 14th
Below is an update to Security Bulletin – Adobe – April 09
Adobe have published a new Security Bulletin and provided updates for Adobe Reader and Acrobat patches. These updates resolve the previously reported vulnerabilities in Adobe Reader 9.1 and Acrobat 9.1 and earlier versions. This vulnerability (CVE-2009-1492) would cause the application to crash and could potentially allow an attacker to take control of the affected system remotely and install Malicious code.
We have already recommended that user consider using alternatives to Adobe reader, this continues to be our current advice. However users still using Adobe should now update and install these patches as soon as practical.
Adobe recommends users of Adobe Reader 9.1 and Acrobat 9.1 and earlier versions update to Adobe Reader 9.1.1 and Acrobat 9.1.1. Adobe recommends users of Acrobat 8 update to Acrobat 8.1.5, and users of Acrobat 7 update to Acrobat 7.1.2. For Adobe Reader users who can’t update to Adobe Reader 9.1.1, Adobe has provided the Adobe Reader 8.1.5 and Adobe Reader 7.1.2 updates.

Kerio Mail Server – Feedback and Updates
May 14th

Kerio have recently introduced a new update for the Kerio MailServer (KMS), which has fast become krayatec’s favoured mail server.
We have now deployed Kerio MailServer 6.2 to most of our clients and despite a handful of teething problems, most are now seeing advantages over Exchange and their previous IMAP based systems.
Feedback from clients has generally been positive, however for two of our clients the switch has not been as pain free as we would have liked and they are still experiencing several issues:
The release notes for the new Update to Kerio MailServer 6.7 suggests that this upgrade will fix most of these issues. The update has now been deployed to our own Kerio system and we are currently testing this in full prior to deployment to our clients systems. After discussing the updates with the Kerio team, we are very hopeful of resolving the above issues. However, it is indisputable that issues may remain with legacy systems, particularity Windows 2000.
Feedback / comments and suggestions for the above issues are always welcome.
