Experience & a good understanding of electronic components with some soldering skills is more what you need not to mention the correct tools for the job. I haven't seen a per say book on 'how to repair motherboards', now there are tons of gearhead articles that people have posted online to help. If you are wanting to actually replace IC's on the motherboard that can be quite complicated cause you need to program the chips & the set of instruction code that the manufacturer programmed the chip with, but some chips can be just as simple as swapping. Anyways if you are instrested in this topic, I recommend just getting a few junk motherboards & just practice with them till you get an understanding of what your trying to acomplish. Hopefully some of these links will help you out.

Its under the optical head. Bye Added after 3 minutes: Hi! The Risk Master Its Sandip Golani.
See parallel port is directly connected to LPC. Stands for Low Pin Count IC, its is generally 128 pin ic Quad Pack. But I Doubt that a decoupling cap. Has shorted therefore the laptop has konged off. Check all decoupling cap. There will be 17 in nos. 8 in data line, 4 in control line and 5 in status line.
Bye Replay what happens. Don't leave your battery unused for long periods of time.
Even if you use AC power most of the time, use the battery regularly to keep it in good condition. Switch off your AC adapter when the laptop is not in use.
This prevents overcharging. To extend battery life, you can try decreasing the LCD brightness while using your notebook. You can activate the `Standby' and `Hibernation' power saving modes, too, for better battery life, you can put off the Wi-Fi when not in use. If you do not use your laptop for extended periods of time-a week or more remove the battery pack from the laptop, but only after discharging it fully. No eating and drinking near or around your laptop. The least bit of water could short-circuit some sensitive laptop circuits, and render it useless. You may sometimes be tempted to turn your laptop off by simply holding down the power button until it powers down.
Although quick, this method is harmful to the laptop and could cause data loss. A hard reboot should only be used as a last resort. Sometimes this is inevitable, for instance, when Windows hangs. But this should not be a regular practice. Don't subject your laptop to jerks and shocks.
This will help avoid damage to your hard drive. Preferably, power the notebook off before moving it from one place to another.
External peripherals and accessories such as external optical drives, PC cards and USB keyboard lights draw power from the notebook. Disconnect such devices when not in use. Booting the notebook when it is not connected to a power source draws a lot of power from the battery. Instead of shutting down your laptop in the middle of a meeting, choose the `Suspend' mode if you wish to use it again after just a short interval.
This will save battery and help you restart your work faster. If you have just shut down your laptop, give it 30 seconds before you start it up again. This ensures that the hard drive has spun down, and is not subjected to sudden switching on and off. Don’t put on the laptop keeping of cloth or bed because generally the air flow is from bottom, regular doing so may reduce the life of laptop circuit. Don’t press very hard the laptop keyboard because, if damaged can cost very high, therefore while playing game use external keyboard.
Hope u readers will like it. Laptop is used to carry from place to placeso people who travel a lot must think of the weight of the laptop. Every battery has a lifetime. So going for a Laptop with hardly any battery backup is not suggested. Minimum of 45 minutes battery backup is very necessary. So while purchasing the secondhand laptop please keep in mind to check the laptop only on battery for minimum 30 minutes and also keep an eye on battery usage indicator. Carry with yourself an audio, video & Blank CD/DVD so that u can check the audio section and video section of the laptop including the CD/DVD read/write test.
Run the scandisk utility available in all versions of windows and check for bad sector in hard disk. Take with yourself any external device like thumb drive to test the USB port.

Take with yourself SD memory card to test Card Reader (If the option is available on the laptop) 7. Take any good floppy to test the floppy drive (Any how current Laptops are not coming with Floppy Drive) 8.
Take an external headphone and microphone to test the external audio port. Attach the laptop to the external monitor to check the external VGA port is working or not. Open any word file and check all the keys are working or not. Check for battery charging for 5 to 10 minutes and see the battery indicator is showing charging.
Press the window and the break keys on the keyboard and see the amount of RAM and CPU details. Further chick the hardware option and then the Device manager to see all driver are installed or not.
There should be no Exclamation mark. Slide the LCD screen slowly on the hinges and check any flicker on the display if so there may be a problem on the connector cable driving the LCD circuit of the laptop. Also check the Modem, Bluetooth & Wi-Fi Port if available on your laptop to be purchased (Do only if you know) I will be writing on these subject next. Check the laptop minimum for 45 minutes to see whether laptop hangs or restarts or shutdowns. See the Laptop User manual and Driver CD are there with the Laptop.
See that u get a laptop carry case, otherwise u have to purchase one. If all the conditions meets out OK and within your budget just go for it. Happy LAPTOPing. Hi, I have messed with my laptop 5 months ago, I was then experimenting on the parallel port barely with some transistors and suddenly these transistors 'feedback' a signal spike to the port and shut off dead my laptop, I was trying to repair it but when I opened it, none of the chips inside is burnt, btw, my laptop model is Compaq Evo N600C what chip should I be focusing on, I have also a repair manual of it, but it doesnt help me I'll be waiting for some response cheers! I have an Inpisron 1500 Dell laptop. It has a DVD compo. It can read DVD only but can bot read CDs.
What is the problem? Hi sant I am 845chip set intel orginal motherboard,which is troubling almost a year.i replaced twice with intel,but problem continues.problem is thermal heating?its shutting down automatically after 15-20 min from boot up.give me solution?I am really fed up with this?help me out? Hi Sandip, I'm not sure if you can help or not, but my PC has been playing up for a while now. A few months ago it started overheating (and shutting down), for no discernable reason, the vents were clear the fans were all working, but the case was quite hot.
This only lasted for a couple of days, and it seemed to be OK, however it is still running quite hot. And when I first boot my PC, the fan monitor (ASUS probe) tells me that my CPU fan is not spinning (which of course it is), for about a minute, then it seems to be able to sense it's speed and the warning goes away.
Apart from the fan warning and the heat, everything seems to be fine. The MB is an ASUS a7n8x v2 delux with a Athlon xp2500. Cheers, Nick.
