I have a 2006 computer that will not power on. After replacing the battery and installing a new screen the computer has been inoperative for a few years now. I prefer to try and repair the laptop before making a decision to have it recycled. Is it possible to do a self-diagnostic to find out what's causing the issue.
Is this a good question?

Does the laptop indicate that the battery is being charged when a known working, compatible charger is connected to the laptop?
If it does, did you also replace the RTC coin cell battery on the motherboard?
If not, remove the main battery from the laptop and then open the laptop and remove the coin cell battery from the motherboard.
Go to p.12 (of 45 pdf) in the service manual to view the procedure for how to remove/replace the coin cell battery.
The battery model number is on the battery i.e. CR2032 which is commonly available e.g. supermarkets.
Before inserting a new coin cell battery, press and hold the laptop's power button for a full 30 seconds and then release it.
Insert the coin cell battery into the battery holder on the motherboard (+ve side up as marked on the battery), reassemble the laptop, reinsert the main battery connect the charger and check if it turns on OK.
There may be a message stating that the date and time are incorrect. This is normal as the BIOS has been reset by the above procedure. Once the date and time have been adjusted, the message won't appear the next time the laptop is turned on

@jayeff. Thank you for your help. Your directions did not produce a result, so my next option is to order a dell adapter, it lights up green and then when plugged into the computer the light goes out.
@freddietoliver just do a few more checks before you purchase a new AC adapter. First you want to check your power supply. Check for the proper voltages. Check to make sure that connectors are not bend etc. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. Clean it of any debris etc, use a few puffs of air to clean it out. If none of this works, get a ammeter and see if your laptop draws any amperage from the charger. After that, you need to check and see if your motherboard even gets power. For that of course, you need to open it up. Post Some good pictures of what you see. That way we can see what you see.

Of course, it is also possible that this is a bad RAM module. So remove the RAM, clean the contacts with a pencil eraser. Do it gentle so as to not destroy the module. Replace it and restart. If you have more than one module, remove it and just leave one connected.
