Same CPU spec ?

Before disassembling the computer, you did take the battery out and ground yourself, right? And I assume you made sure to ground yourself before touching the CPU and/or motherboard, right?
As long as you didn't static shock anything, the only other worries could be that you didn't install the CPU firmly into the socket, you didn't close the socket properly, you failed to reconnect one of the flex cables (jumper films) inside the computer, or one of the circuit boards wasn't firmly seated into its socket.
In some laptops, replacing the CPU will require removing the CMOS battery and waiting 30 minutes or so, or else it won't boot. Furthermore, some manufacturers (especially Dell) will disable certain CPU's in the BIOS, preventing startup with those processors installed. Usually, it will display an error message such as "Incompatible CPU detected, system halted" or "Unsupported processor installed, press F1 to continue".
One thing that you should be aware of is that most laptops use a thermal pad on the heatsink, which can only be used once. If you read the service manual, you will see than anytime the heatsink/fan assembly is removed for any reason, you are supposed to replace it with a new one.
The way I get around that is to scrape off the thermal pad and sand down the bottom of the heatsink, then clean the heatsink and processor with rubbing alcohol, and then apply thermal grease to the top of the processor die. Remember that you should only use white grease (silicone-type grease) in a laptop, NEVER use Arctic Silver or any other type of metal particle grease.

Make sure that the new processor has the same socket number as the new processor. Ex. 743, S1. Also, make sure your notebook has BIOS support for the processor. If you made the jump from a 32-bit or 64-bit, Single-Core to Core Duo... etc. I think that's the problem, find out if your BIOS is compatible with the new CPU. If you are able to see the BIOS, try turning down the CPU Voltage to see if that helps.

did you close the lockscrew?
System may not boot, lights may not come on
Is the CPU > 30% faster than previous CPU
If the ram is too slow, it won't startup.
What Laptop and Model
What old cpu speed & new cpu speed?

Run your pc with your adapter. Then, come out your battery and wait a minute and then positioned it back in. try besides it up and notice if that facilitates. from time to time my pc gets locked up on me and that does the trick.
