Let's see what Aleksandar was fixing today.
My findings, tips & tricks related to computers, internet, programming and other stuff I was working with.

Fixing power connector on ASUS M6000 (M6N) laptop

Today I got ASUS M6N laptop for repair. It did not want to turn on and also it does not give any sign that it’s charging the battery.

Laptop was previously sent by it's owner to ASUS repair center and paid 70 EUR only for diagnostics. ASUS came up with 600 EUR bill for repair so owner did not accepted the offer. They suggested motherboard and HDD replacement (?!). I did not understand why HDD because HDD works just great.

Anyway, laptop finished at my place and after 1.5h work laptop is working again! It needed some dust cleaning and bit soldering...

First I had to find disassembly or service manual. Bit of Googling and visiting some favorite sites I found the manual here

After laptop is taken apart I made these pictures (click on image for high resolution):

CPU and surrounding covered with dust.

Loose broken power plug and very dirty fan

Again broken plug after I have "shaked" the laptop a bit. Now you can also see the rest of the power connector.

Bigger picture of the open case and power connector location

Here is the "guilty" part

Which came out from here... Good luck that motherbord and othr parts are not affected with accident

After operation it looks like this. Metal part is soldered properly to the motherboard.
I have melted together top part of the connector case to assure better joint.

As you can see everything is clean and neat again.

How to enable AHCI mode after installing Windows

AHCI (Advanced Host Controller Interface) is present on newer Intel chipsets such as 975X (ICH7), P965 (ICH8), and P35 (ICH9). AHCI mode is enabled in the BIOS and 3 settings are commonly available: IDE, AHCI, and RAID. The last two (AHCI and RAID) require a driver floppy and the F6 method when installing Windows XP otherwise the hard disks won't be detected.

AHCI mode brings 3 main advantages:
Supports NCQ (Native Command Queuing) allowing SATA drives to accept more than one command at a time and dynamically reorder the commands for maximum efficiency.
Supports hot plugging of devices
Supports staggered spin ups of multiple hard drives at boot time

However, in the real world the performance difference isn't huge.

The problem is that if you installed Windows in IDE mode (i.e. you didn't use F6 and supply a driver disk), then simply changing the BIOS setting to AHCI mode and rebooting will cause Windows to fail and will require a repair install. Most people have been advising to reinstall Windows if you want AHCI enabled.

Few Notepad trick and tips

How to Use Notepad to Create a Log File

Microsoft Notepad is a word processing tool included with Windows and is installed by default under the Accessories program group. You can use it to create a log-type file that adds the current date and time each time the Notepad file is opened.

To create a log file in Notepad:

  • Click Start, point to Programs, point to Accessories, and then click Notepad.
  • Type .LOG on the first line (case sensitive), and then press ENTER to move to the next line.
  • On the File menu, click Save As, type a descriptive name for your file in the File name box, and then click OK.
  • When you next open the file, note that the date and time have been appended to the end of the log, immediately preceding the place where new text can be added. You can use this functionality to automatically add the current date and time to each log entry.

This cool notepad trick can be used to make daily notes or can be used as a diary also.
You can even press F5 to get the current date and time anywhere between the text.

Want to get rid of default page header oand footer in notepad?
To do this click on file -> page setup, remove the characters in the header and footer textboxes and write whatever you want.

Also, you can print other information at the top of each printed page in the file.
To have Notepad print information in the header, use the letter and character combinations in the following table.

Align the header to the left, center, or right. &l, &c, or &r
