If you want to sync your iPhone notes directly with your IMAP account (not a GMail account) and not through iTunes, you may encounter some issues like i did.
First, a little info about this feature introduced with iOS 4. You can sync your notes in multiple ways :
– with iTunes, and from there with GMail.
– directly with GMail if you configure your mail account from Settings – > Mail, Contacts, Calendars -> Add account -> GMail.
– with an IMAP account on a different server, other than Google. Continue reading

It seems that the BIOS reverts to its defaults values on certain situations (loss of battery power, BSOD, etc).
One setting is the SATA native mode : AHCI mode instead of IDE.
Because XP was installed with BIOS set to IDE, this keeps Windows from loading, resulting in a BSOD.
Also, using AHCI should improve battery life and HDD response. Continue reading

I had a Lenovo IdeaPad U350 downgraded to Windows XP. In order to make the wireless card work, you must install first Lenovo Energy Management utility, in order to make Fn+F5 buttons work. Also dont’t forget about the wireless switch located in the left corner of the laptop.
You will also see the third LED on, under your touchpad.

Wireless adapter type : Broadcom 802.11g Network Adapter
Hardware ID for Broadcom 802.11g Network Adapter : PCI\VEN_14E4&DEV_4315&CC_0280

The image below is from a computer with issues on it’s motherboard and also a faulty RAM. If memtest is started for the first time it shows the RAM having an error around 399MB address. If I choose to restart memtest this is what i get :
Memtest red line
The board has problems powering, even if all other components are changed (including PSU). I can only power the board only by keeping the power switch on and plugging the power cord. I’ve changed the power switch too.

After upgrading to ESXi 5.0 from ESXi 4.1 Update 1 because I could not install it on my LSI 1064E hardware RAID, my IBM x3250 4364 server showed poor I/O performance when downloading stuff. In the logs the message was :
Device xxyyzz performance has deteriorated. I/O latency increased from average value of 80631 microseconds to 3395272 microseconds.
You can see the screenshot with the error logged below.
ESXi 5 problem on LSI 1064E
My solutions are : try another pair of HDD’s, try another controller model (i only have this one), or try VMWare ESXi 3.5 U3, according to this post.
The RAID Bios version is the latest : 6.22.00
The firmware version is : 1.18.86.
It seems that there are 2 versions of LSI 1064E controller : 1 MB and 2 MB.
My IBM x3250 4364 has the 1 MB version. For those who have the 2 MB version (newer servers), here is a link.
I will update this post as soon as I find the best solution.
Update 1 – 23.11.2011: Leaving only one HDD made the ESXi 5 unable to boot. I’ve used the other HDD and i had the same result. So RAID1 in my case didn’t work for booting, but the data was there.
I used only one HDD, and installed ESXi on a USB stick. But the “performance has deteriorated” warning it’s still present.
Update 2 – 3.01.2012: Write caching was disabled for the LSI 1064E card . I enabled it, but i still have the same message.
