IBM Thinkpad L40 Display Problem

I was asked by a friend to check on an IBM Thinkpad T40. The laptop is owned by an NBI Agent whos complaining about its display problem. Sometimes, it starts well and then the screen “blackens”. When I checked the laptop and perform several test, I encountered beep codes, one long beep and two short beeps. These beep codes means a display error according to Phoenix BIOS codes.

My action then was to dis assemble the laptop and try tohave a visual inspection inside. Since the problem is more on the hardware component. I tried to press the IC’s inside it for a possible “chip creep”, specifically the one that concerned the display problem. As I assemble it back again, I also make sure that it is properly done (i.e. I took my time).

When I turned on the laptop, it works fine. In order to make sure that the problem was solved, I perform several test. The next day returned the laptop for free of service believing on the concept of reciprocation. Anyway, I have an add on on my experience.

reagards,

Samsung Sens R45 Driver Problem

My friend complained about the slowing performance of his Samsung Sens R45 laptop computer so I have to check it out. I used PC wizard to check the system information and I got some details. I use Windows Mini XP loaded from my 8GB flash drive, to see its performance with a minimal system. The PC works fine with so I decided to reformat and reinstall Windows XP SP3. After the installation, I noticed that the laptop does not have drivers loaded for its display, network, and audio components. I tried to download it from the net but the drivers did not work. I also tried reinstalling the system using Windows Vista but still the devices are not supported. With a little bit of patience, finally I found the driver at http://www.samsung.com/ support section. Right now the system works fine with Windows XP SP3 Black Edition.

A Reunion with an "Old Friend"

Hi Guys! I was called by a Law Firm to check on their PC. They told me if that their PC is not working properly and they can't install their newly bought printer.

I just remembered when I was in 2nd year in college when I first have my PC hardware experience and training. I was supposed to apply as a computer laboratory student assistant when the laboratory head asked me if I had knowledge on PC hardware. It was 1997 that time and I have used PCs and Apple II during my high school but just an exposure with WordStar and Turbo Pascal Language. So, when I told the head about my PC exposure, he s...
