Motherboard Repair
I had stopped repairing PC motherboard since i left my former computer distributor company back in 1994. Those days the famous motherboard board were the 486sx, 486dx and the Pentium. I was provided with every model of the motherboard schematic diagrams, Chipset (all range of IC’s), SMD desoldering tools, troubleshooting notes and even the POST diagnostic card. Repairing PC motherboards on those days were quite easy but i doubt nowadays it will be easy unless you are working in the motherboard manufacturers or you have the sources for all kind information related to motherboard.
Occasionally i do have motherboard sent for repair by my friend who deal with selling computer systems. Most of the time was the electrolytic capacitors bulged and quite simple to fix it. Nowadays PC motherboard is quite cheap and less people want to repair it and prefer to buy a new board unless if the motherboard is in the higher range (branded). As mentioned, if you can’t source for the parts it would be very difficult to repair the board. Those days the boards were only using normal SMD IC’s (spider IC’s) but most of the motherboard now are using the BGA IC’s which is very difficult to extract unless you have the special equipment to do the job.
It will be very time consuming to do this precision job unless the profit that you gonna make could cover your cost otherwise it would not be economical to repair the motherboard. If any of the readers in my blog repair motherboard i would like to listen to what you have to say about motherboard repairing business-thanks

HI Sachee,
It is not easy to repair motherboard if you can't find the parts. This was one of the reason i do not repair motherboard anymore because of no parts available and the new board is cheap.

To remove the dust you can use a vacuum cleaner with a brush.

Apart changing the buldged capacitors, cleaning the mainboard due to rust etc, loose connection and dry joints there is not much can be done on the mainboard unless you really have the parts (ICs) for replacement.

Hi there. I have a Acer Aspire 5520-5277 that will not power up at all. Only the power LED blinks.(3 secs on, 2 off, 3 on, then rapidly for ever) I am most likely going to trash the Mobo, as all the components are working fine (tested in another unit individually) Batterys good, Charger is good. . Ive scoured the net trying to find somewhere i can get a schematic or info on where to look on the board itself for the issue, but no luck. I seen your ad on Ebay and looks like you guys know your stuff. I don't have money to spend on getting it repaired or a new laptop for that fact. I repair electronics for a hobby, and a Mobo is new to me, but am confident enough to get into it. Would you be willing to give out some advice or solution or help LOL 🙂 If you need any more info from me, please don't hesitate to ask. Thanks for your time, Yan Svenson

HI Pramod,
It depends on the problem of the motherboard in order to troubleshoot it. Communications and Network Riser (CNR) is a interface on a computer motherboard for interfacing a communication device or peripheral.
