Buy a new case. Even though you can get quite a number of motherboards to fit. You will never get the front panel connections on the new motherboard to match up with the custom front panel wires on the Lenovo case.
That's a pretty lengthy answer that would be required. Basically, open up the machine, unscrew the motherboard from the case, disconnect all the wires to the hard drive,CD, power supply, and then lift the motherboard out. Reverse the process to replace it. Pay attention to the wires that go to the motherboard from the front of the case. These need to be put back in the same locations on the new motherboard.
Some times the AC adapter and battery dies and saves your laptop motherboard.
Follow the following steps to check once again. Remove the battery and the defective adapter and check if you can borrow a known good working adapter and see if your system works / turns on just by connecting the power adapter and turning it on (without the battery) if it works then repeat the check with the battery on.
If both the test works then your adapter is the only issue, get it replaced. If both fails, you have to replace or service your motherboard.
are you sure your are exiting the bios saving your changes? if for some reason you are unable to save your changes it is possible that the cmos battery is going bad, replace the battery and test.
another reason why you may not be able to make any changes is because you may not be a supervisor or accessing the bios as a supervisor but as a user. you may have set a bios supervisor password. if you don't remember what that was you may have to reset the password:
to reset your password do the following:
Turn off the computer.
Open the computer case.
Locate the blue J8C2 Flash/PWD jumper block on the motherboard.
Place the jumper on pins 2 and 3 for clearing the passwords.
Turn on the computer. Wait for an audible beep from the
computer. A message appears stating that the NVRAM and password have
been cleared.
Turn off the computer.
Place the jumper back on pins 1 and 2 for normal operation.
those arent seriously important wires anyway
all they do is make it so you can use your front usb and audio jacks
you should have the same ones on the back of your mobo
you can try finding those wires from your case maker
what brand case is it
try going to there web site to see if there available
if not you may have to soldier them together to get them working again...
one more thing
try ebay
maybe someone is selling those wires or just the front part of that case
good luck
Lay case down with the bottom in front of you. Looking straight down at the row nearest the case bottom reading right to left there will be two rows of four pins.
Reading right to left the row closets to the case bottom the first lead is vcc1, next usb1-, next usb1+ and grnd1.
Top row reading right to left is vcc2, next usb2-, next usb2+ and grnd2.
