hello to everyone... all are saying simply change the motherboard if that is dead...but some technical guys are known to repair it..but i didn't know how they do and i still search in net to get details about that...IF ANY ONE KNOW TUTORIAL OR EBOOK PLEASE POST THE LINKS..because some simple short in pin can make motherboard not working and we spend more money to replace..

— a few focused checks will usually tell whether a board is truly dead or just unhappy with a peripheral or setting. Several replies in this thread debate repair vs replace; the short workflow below helps decide which path makes sense and what you can safely try at home before spending money or time.

Quick, noninvasive checklist (10–30 minutes):

  • Remove all drives, USB devices and add-in cards so the board is bare except CPU, one stick of RAM, and PSU/charger. Try to boot and watch LEDs or listen for beep codes.
  • Swap in a known-good power supply or charger if available. A PSU that shows correct rails but still won’t boot points toward the board.
  • Test one RAM stick in each slot and try an alternate stick if you have one. Faulty memory or slots often mimic motherboard failure.
  • Reset BIOS/UEFI settings by removing the coin cell for 30 seconds or using the clear-RTC jumper, then try booting again.
  • Do a careful visual inspection under good light: broken connectors, bent CPU-socket pins, corrosion, or burn marks are meaningful clues.

Simple measurements and next steps:

  • With a multimeter, check the main DC rails from the PSU (3.3V, 5V, 12V) and the standby rail. If you are not confident using a meter on a live board, stop and get help.
  • If the board shows power but no POST, try a POST card or documented BIOS recovery methods for that model. If the system POSTS with minimal parts, add components back one at a time to find the culprit.

When to stop and consider replacement or pro help:

  • If tests show a direct short across a power rail, visible burned areas, or no change after the minimal-boot steps, the fault is at board level and needs shop diagnostics or a compatible replacement board. Match model and revision numbers carefully for laptop boards. Always unplug power and remove the battery before working on any board, and back up drives before any major repair or swap.

Most modern boards are wave soldered, and are heat sensitive. Repairing them (removing, replacing soldered components) requires skill (experience) and specialized soldering tools. It can be done, but not usually by an inexperienced technician. Example - an on-board capacitor has failed and needs to be replaced. Finding the proper replacement part is usually not difficult, but replacing it is not so easy. It takes practice, and as I said, requires the proper soldering tools to do this.

most motherboards are not worth the repair cost ,cheaper to replace it .

Well, if the failed part is simple (not an IC, but just a capacitor or resistor) and you have the equipment and skills, then it can be a lot cheaper to repair. Example: a client needs a mobo for his HP laptop. Replacement w/ exchange is almost $270 USD. If it were a simple cap replacement, the part would be a few bucks (including shipping), and it would take 5 minutes to R&R. However, if the part was an IC (more likely), then the likelihood of a reliable repair goes into the crapper and replacing the mobo is a better option.

You should go to the service center of that your mother board, ask them if they can repair your mother board. :)

Or if you live in California then just drop by the phoenix foundation and Macgyver can fix it for you. I'm sure if you provide him a pin, some duct tape, blue tack and don't steal his Swiss army knife then I'm sure he can fix it in no time. In fact I saw Macgyver fix a motherboard in season three I think it was.
