How Do You Take the Battery Out of the Motherboard?
Unplug the computer,('natch), open the computer case. This varies from, computer to computer. (After I open the case, I unplug the cords that will get in the way, then lay the computer on it's side, referring to tower desktop models) Locate the CMOS round nickel size battery. Look at the holder it snaps into. On each side will be metal strips, that lock it into place. Gently use,( I say gently because you can bend the metals strips), a non-metallic object, like say a fingernail,(if they have a little length, call your girlfriend over!), and move one of the 'strips' to the outside a little. If it acts like it doesn't want to move, don't force it, go to the other side. One side will have a spring action of sorts, allowing the battery case to move up on one side. Be sure you have the correct battery number,(like 2032), for your CMOS socket. Oh, by the way, they all go with the + facing up. (That's the Positive end marking) EDIT: Forgot to add. Do this on top of a wooden table,(or fake wood), if you can. DO NOT do this sitting on a carpet floor. Touch the metal sides of the computer case frame, before stickin' your hand/s in there. This will de-static you. Best done sitting on a chair, but that's just personal preference for me. If you get up, to get the battery from somewhere, touch the case frame again. STATIC kills computer parts!!
What are the ways to replace a built-in battery in my Lenovo IdeaPad P400?
**EDIT**Here is a teardown of one This person makes the common mistake of not undoing the flat screws I mentioned in my walk through so watch to the end before undertaking work. *close edit* I haven't disassembled one before but I'd be fairly certain it would require the following in similar order:Disconnect any cables, Unscrew all screws on bottom of laptop paying attention to the sizes of the screws incase some differ. Of there's any hatches (i dont think there is) , open them and check for more screws.One of the screws, should be labelled and should release the DVD drive (this may be a different size screw), so pull the drive out. You may have up to 3 very short screws with large flat heads screwed into the case where the DVD drive used to be so ensure they are undone. Once you are sure all screws are out (especially ones marked for keyboard), flip it open and carefully remove the keyboard. This probably gets clipped out by 3 or 4 points at the top of the keyboard, a plastic prising tool (or 2 together) should be used. Now check if there are any screws that are under where the keyboard was screwed into the Base of the laptop. They are usually marked with an arrow and sometimes the size of screw eg. 2.5 or 6.5mmOnce this is done ensure nothing is left sticking out and close the lid and flip upside down again. It should be safe to prise apart both halves of the laptop case, again do this slowly and methodically, try starting from the DVD drive 'gap' (A warm environment is usually better as there's less chance of any plastic clips snapping) Now you should have the internals exposed so you should get a good idea on where the battery is, take usual precautions when handling sensitive components.
What do you do if your computer won't turn on after a power outage?
I think you should start with some of the basics that possibly you might not have considered.Is your computer plugged into a surge protector, and if so, does it have a circuit breaker? If so has it been tripped by a surge when the power was cut off or brought back. If the surge protector doesn't have a breaker, has the surge protector "burnt out" by a surge. Reset the breaker or replace the surge protector. It has done its job.Does your computer's power supply have a breaker? Is it tripped? If so reset it.When you attempt to turn the computer on, does the fan on the power supply turn? If it doesn't there's a chance the power supply isn't working and may need replacing. That could be cured by replacing the power supply or replacing the whole case and power supply.If you have the case open and start the computer does the cooling fan on the CPU run? If it doesn't there may be problems with power to the board. You might be looking at replacing the motherboard, CPU, or both.Do the drives run even if the CPU isn't running? The motherboard, CPU, or other important components may have been harmed by surges.If your computer can not be restarted and you can't figure out what has failed. Remember, in truth your computer is not the computer itself but what is on the hard drives. You can take those drives out and place them in another computer... but you might want a tech to do that who knows what they are doing with regards to re-registering the operating system.If your computer has a built in speaker... I know that might be archaic technology, but... computers have something called a POST test. The POST test will play a series of beeps on start-up and the pattern will tell you what has failed. If all is well, that is what produces the beep you hear when starting a computer.When I last had a problem like this... I came home after an extended absence and there had been a substantial spike on the power-lines due to a power-line tower collapsing into the Fraser River. Even though my electronics were Off, and protected by surge protectors the surge got through to the CPU of one of my desktop computers, gateway router, a printer, and a scanner. I cured the computer problem by transplanting the drives into another computer case that had a working motherboard and CPU in it.I am a bit rusty in my computer repair skills, but I hope some of this may help.
Is it possible to fix a motherboard with bent pins?
Yes, a motherboard with bent pins can be repaired if it's not too damaged.Depending on how skilled you are it might a lot of time though.You will need a good pair of tweezers with sharp tips, a bright lamp toilluminate the motherboard while you're reshaping the pins, and a lot ofpatience. If you're not careful, a pin might break off, and then yourmotherboard is definitely beyond repair.I have had a LGA2011 motherboard with bent pins (due to a botched CPU installby myself) and carefully restoring the pins to their proper place with tweezersmade it work again.

How can I remove the Bios password on my Dell D430?
There are two passwords in BIOS. One is start up password, the other is BIOS setting password. If you have forgotten the start up password that means you cannot open computer at all. Then the first method is the only thing you can do. Other methods can use to clear setting password.
