Higher voltage then required is not so recommended, internal circuit may over voltage driven. some power amp max limit may fall within 18V only. See this link If your speaker power less then 30w you can choose 15V 2A will do or else select higher spec.

Good Day Psmith!

It looks like the AC adaptor is not making the right supply voltage needed for your laptop.

If you have a multi tester, you can test your ac adaptor to see if it has stable 20V voltage output supply needed for the laptop to make it work.

Set your tester to DC range. Plug the ac adaptor to your wall socket. Hold the other end of the ac adaptor (the one you connect to your laptop. Insert the red (positive) lead into the center of the adapter pin, then touch the black (negative) lead to the outside metal part of the pin.

Read the display in your tester. If the adapter is working properly, the meter should read between 19 to 20 volts of the rating. If the adapter is faulty, the meter will read below 18volts.

If that would be the case, I'm afraid you will need to replace your ac adaptor.

You can purchase online a replacement ac adaptor for lenovo 8932.

Please accept my answer if this is the information you need.
Don't forget to give a four thumbs up rating!
Thank you for asking Fixya.

you may have to take it so a shop and change out the power supply on laptop 

Please turn off the Computer and disconnect the AC Adaptor then remove the Battery. Next, try cleaning the metal contacts on the Battery and reseating the RAM modules.Then, connect only AC Adaptor to the Computer and try to turn it ON without the Battery. If the Computer doesn't turn ON then disconnect the AC Adaptor and insert the Battery then try turning ON the Computer. If the issue persists even after performing all the above steps then service will be required.

Keep in mind since you cleaned it out, only have the AC adaptor hooked up to rule the battery out. If the laptop stays on with only the ac adaptor hooked up and doesn't shut off then you know that the battery is faulty. If it still shuts off even with just the ac adaptor hooked up then it could be the ac adaptor.

Also check one more thing, with only the ac adaptor hooked up, wiggle the cord where it plugs into the laptop and see if the laptop shuts off, if it does then the dc jack on the motherboard is loose and needs to be resoldered back into place so it stays put.

Here is one on ebay:

Sounds like you may have a problem with the internal power supply box? I am not sure but that may be at least something for you to have checked out. If the fan is not spinning this is usually a sign this may be what the problem is. GOOD LUCK!

The Pin Assignment is as follows:
Pin 1,4: +5V
Pin 2,3: not connected
Shield: Ground
The AC Adaptor is specified as 5V , 4Ampere. Actually the unit draws around 2-3 Amperes.

This "Image" shows the pins, when you look onto the jack at the back side of the terminal, with the terminal standing upright. The label = 5V is located left of the jack

Below is the URL for compaq's Service Manual for that model. This shows you the details of every single part & how to disassemble and reassemble every screw. Surely it has to be in this document, somewhere. --> ftp://ftp.compaq.com/pub/supportinformation/forum/portables/7400msg.pdf
