There are several ways on which you can reset the cmos in your pc, most common ways are removing the battery (like what you did) or doing a short circuit on the battery or reset pins. However there are some manufacturers now that use a different method, I had a dell PC before where the reset pins are already shorted, to reset it, I had to remove the jumper, power the device for 10sec, power it off then put the jumper back, kinda odd but I guess that how dell wants it, you can try that method as well. there are some that requires a key or before it could be reset like what I heard on some HP brand computers, the use has to call HP, then they ask for the serial or something then give ot generate a key. The best advise is to consult the documentation or vendor of your laptop for details on how to get your reset your laptop.

See if the a/c >> d/c input connector on the rear right side of the unit - if so you've damaged the connector to the input board and a/c will not flow. Also try another 65w compaq or hp external power supply. They do have a tendancy to fail. Now if your a/c power supply is ok then you will need a replacement A/c converter board that is a separate component board attached to your m/board. The part number from Hp is as listed - if this corrects your fault rate my assistance. The N610c are a very good laptop my daughter still has her that I got her from new.Parts listing for unit can be found here >> http://partsurfer.hp.com/cgi-bin/spi/main
Voltage converter board (DC-DC converter)
Try this: -
Remove your Laptop Li-ion battery module. Then remove the RTC battery for at least 15min. Replace RTC, and boot the computer ONLY with the AC-Adapter. Enter the BIOS and set to boot from USB
Removing the Time of Year battery will clear the BIOS password. It is located on the underside of the n610c behind the panel covered by the Microsoft COA label. A small phillips screwdriver is required to remove the two screws on the panel. Carefully lift the BR1225 battery with a small flat blade screw driver.
After 10 minutes re-insert the battery. The BIOS Password should now be cleared, as well as other BIOS settings, the time and date.
