Question:



Would love to know how you diagnose motherboards on a component level. What tools do you use?


Answer:



I find it is very hard to explain this. actually, it is very simple and can be described in two words: current and singal. read the current change during booting tells you where the machine stopped. check the singals on the different part of motherboard tells what is wrong or what may missing.

Tools are: smd rework station, bga rework station, power supply has current meter. all the rest tools you can find in any radio tv repair shop.of course all the datasheets for the components, especially the schematic diagram, you will find it much difficult without it.


Question:



What are common faults on mainboards?

Do certain components fail? Is there a trend as to which parts fail quite often?


Answer:



Different maker/model has different common fault. Toshiba S1 is vga chip, and can't be repaired(well, almost can't be repaired because the pcb quality is not very good so successful rate is very low).
HP DV2000, 6000, 9000, compaq v3000, v6000, dell 1210, all those use nvidia chips have problem on vga chip or north bridge. easy to repair but have to make fan keep spinning after repaired, otherwise will break down in 1 or 2 week again.

hp nx5000, cpu pwm chip dry joint. acer 290, cpu pwm dry joint.
hp dv1000, compaq m2000 protection circuit easy to blow up.
ibm t40 vga dry joint problem.
These are just few of them. every machine has its own common fault. but dry joint is the common problem for all machines. Motherboard repair is not as difficult as people thought, i think much easer than repair a tv.


Question:



Dell 1525 Inspiron that says system does not recognize the installed battery this system will not charge the battery.


Answer:

Charging battery in Dell laptop involves two major chips: EC(or someone call it super IO), PWM chip for battery charging. BIOS has no part of charging. Battery communicate with EC through SMB(system management bus??) and EC controls charging PWM. Fix charging problem is very hard in laptop repair, you must fully understand schematics, where all the signals come from and where to go.
Today's laptops are less and less with programmed EC, Dell 1525 has no programmed EC so it can be replaced with same model.


Question:



 How i fix a DV6 with power problem. The problem of machine is it cannot power up at all.


Answer:



Doing routine check:
1. system power: 3V, 5V all presented - ok

2. NBSWON signal: 3.3V presented - ok

3. press power button, NBSWON pull down to 0V, ok

4. check DNBSWON while press power button, no response. - problem.

in here I made a mistake, I didn't pay attention of the voltage of DNBSWON, this mistake waste me the next few days time. It should be 3.3V, but only about 1V.

Change EC as usual, because I thought the EC has problem. Then the big trouble comes - it auto power up once I plug in the power but stop in 0.04A current. Check and find no S5_ON signal, which indicate south bridge has problem, so change south bridge. But still same problem and still no S5_ON. I find that the EC I change is kb3926A rather than kb3926C. In most case, this is no problem but in very rare occation...
So I find a 3926C and put on. Now the motherboard is back to the same problem while I first start to check! So I change a wrong EC and this time I change a correct one, and also EC has no problem!

Because EC will start to read bios once the power plug in(not as people think, once you press power button). I check BIOS chip, BIOS_CS should have a countinue wave form but it just one stright line. BIOS chip is faulty, I replace the BIOS chip and it works perfect.

Screen Corruption

Laptop display problems are also caused by a faulty screen or VGA chip on the motherboard, which can affect the display. 80% of the time its a fault with your onboard Graphics Card. These graphics chips are BGA form factor, Ball Grid Array chips cannot be resoldered using convention soldering irons.

Common Symptoms are:
+ Multi Colours
+ Multi unknown alphanumeric characters

Virus Removal

Hands down our most popular phone calls are about computer trojans and viruses. Today virus authors are releasing malware at an alarming rate. Anti-virus companies like McAfee and Symantec are detecting 5000 new viruses per day. This means it’s getting harder for the anti-virus vendors to keep up with all the new detections and ultimately means they cannot stop all the viruses that come out on a daily basis. This leads to home users getting infected even if they have up-to-date anti-virus protection. Since your current anti-virus product can’t help you, manual intervention is required by our live technical experts. Here are some common symptoms of infection:

    Strange Messages from Windows
    Anti-Virus Software is disabled or inactive
    Very slow computer when performing common tasks
    Redirection to fake websites when working
    Random reboots while working on your PC
    Very slow Internet access while browsing
    Pop up windows telling you to pay money to fix your PC
    Pop up windows trying to sell you software or services
    Degrading performance as time goes on
