I have a NEC versa 2635cd laptop. I have not used this computer over the last two years, but recently had a need for it. When I used it last there were no problems at all but now when I plug in the ac power supply and push the power on button nothing happens. I'm sure the battery is dead but I do not believe that you need the battery to run on AC do you? The indicator LED on the laptop lights up when you plug in the AC adaptor but the computer does not boot up and no screen activity. I believe there is another battery in this computer a cmos clock battery, if this battery is dead will that prevent the computer from booting up? Any technical advise would be appreciated Thank You!!!!

It is unfortunate that the computer is not turning on. Request you to try following the below steps which might help:
(1)Turn off the computer.
(2)Remove all the external peripherals like AC Adaptor, flash drives, battery, etc.
(3)Press and hold the power button for 30sec which releases the static on the computer (if any)
(4)Put back the battery and plug in the AC Adaptor.
(5)Let the computer charge for some time.
(6)Try turning on the computer.
If the computer doesn't turn on then check hoe the Power LEDs on the system, battery and AC Adaptor react. Then I can check and help you further.

look at the bottom of the laptop where you install the battery, there's should be what looks like metal contacts where the battery connects to the actual computer. make sure that when you installed the battery you didn't accidentally bend 2 of them so they were touching eachother. you may have created a direct short which is what caused your heat and the smell. try to plug the battery back in and be careful that you don't bend the metal contacts.
Its an old trick that got my Dell laptop working
Unplug the laptop
remove the battery
press the power button,...nothing will happen,
wait a few seconds
put battery back in laptop
plug it in
hold upside down
press power button until it boots
If that doesn't work it could be a bad/loose/dead bios battery
What is the model of the laptop?
Shutdown the system , and disconnect the battery from the laptop.Also disconnect the Ac adapter. There is a button the battery , press and check if there are any light the glow on the battery. If there are no lights that glow the battery is dead.
Press and hold down the power button for 10 sec. after removing the battery and the Ac adapter
Reinsert the battery and connect the Ac adapter
1.Power on the system and tap on f2key slowly five to six times on the Dell logo screen
2. You would enter the blue screen
3. Using your down arrow key, go to the option that says battery info or battery health . Check if there are any error messages on the same. If the battery is not detected you would have to replace the battery
** Note ** normal life expectancy of the battery is one year.

when any computer posts/boots up.
it goes through a sequence of initialising things before booting.
i,ve been repairing computers for around 12-15 years.
1st i,d try removing the ram ( memory ) usually underneath the laptop, behind a screw cover. Or ocassionally under the keyboard.
if 2 sticks of ram are installed, remove the battery. and 1 stick of Ram. put battery on and try to boot. if no joy with that try the other stick of ram. and replace battery-Re-boot.
If this works you have 1 stick of faulty ram or faulty ram slot on motherboard. Failing this. I suspect that the CPU has overheated, and therefore a replacement Processor should solve the problem.
This sounds like a weird solution, but it worked for me. I recently bought a used Presario 2500, it worked when the guy showed it to me, when I got home it didn't work two days later. I tried several tips from the web, finally I started pushing several buttons randomly. I pushed the Email (Envelope) button, and the computer powered on suddenly. Now, the Envelope button is the only button that will power the computer on. When the computer is on, that button will also bring up Outlook, but when the computer is off, that button turns it on. Let me know if this fixes it for you.
