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.

Sharp PC-MC30F Mebius Laptop Power Problem
Hello Guys!
Here’s another problem on PC and Laptop Repair. This time, a cellphone technician was referred to me by a friend check his Sharp PC-MC30F Mebius for a power problem. He is complaining on an unpredictable power failure on his laptop. When I checked and turned on the laptop, It doesn’t turn on with the battery on it. So I tried to plug it in without the battery, and it powered up.
I tried to enter the BIOS setup and see some specification of the laptop. I was also to enter the Windows XP system and run dxdiag and device manager. After a short while the laptop shut down. I also notice that if I put some pressure on the keyboard or the palm rest the same thing happens. The laptop specification is shown below.
DXDIAG Results:
System Model: PC-CL/MC
Processor: Mobile AMD Athlon XP-M 2000+, 1.7 GHz
Memory: 1 GB DDR400 RAM
Video: S3 Graphics Pro Savage DDR, 32MB
Audio: C-Media Wave Device
The symptoms, i guess, maybe a shorted power circuit. So I decided my first action to disassemble the laptop and perform visual inspection inside. I recorded my steps and photographed the FRU’s as I perform the procedure. Just making sure that I will be doing the right thing because I can’t find any manual of the said laptop model.
Right now I’m still continuing my test and diagnostic procedure… and I willjust edit this last line as soon as there is a progress.
Good Luck to ME,
