"just blank blue glowing screen."

A regular blue screen, or do you mean the display has a bluish tint to it all the time?

If a regular blue screen, like you often see when you get a Windows error message, does it ever have an error message on it, and if so, what does it say (e.g. STOP: 0X0000....)

"using a seperate monitor got a error that memory could not be read"

Several things can be wrong with hardware that can make the LCD display tinted a color all the time, or produce no display or a diminished display, but in most cases, an external monitor will still display fine when plugged in.
Obviously the computer was having a problem reading it's ram.

Did you change which ram you have installed since the computer last worked properly?

If you HAVE, it may not be 100% compatible with your computer. If you still have the ram that was installed when the computer worked properly, remove the new ram, install the old ram.

"tried reseating the ram."

You must remove both its main battery and AC adapter before you do that. If you didn't do that, you may have damaged the ram, and/or the ram slot circuits on the mboard.

Sometimes you also need to clean the contacts on the ram.

A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

For a laptop, you must remove both its main battery and AC adapter before you do that.

While you're at in, with the power removed, make sure the hard drive is properly seated.
.......

Most more recent laptops (e.g. newer than 5 years old) will not run on the AC adapter alone. The main battery must be installed when you use the AC adapter, and the battery must be capable of retaining at least a minimal charge level, and be charged to at least a minimal level, before the computer will start up.
If the battery does not have a sufficient charge, the computer will not start up until the properly working AC adapter has been plugged in and the battery has reached the minimum charge level.

There is probably a "charging" led that lights up on the front edge (blue? left corner?) of your laptop that indicates the AC adapter is working and is charging the battery (if your not sure where or which one, see the user manual for your model or model series). Even if the battery is fully charged, that led should come on briefly when you un-plug the AC adapter and then plug it back in. If it doesn't come on at all, the AC adapter is no good, or, more likely, the plug or it's wiring there that plugs into the laptop is damaged. If that led NEVER goes out when the AC adapter is plugged in, the main battery is probably defective (e.g. is shorting internally).
The HP/Compaq AC adapters I've seen have a removable cord from the adapter to the laptop - if the chargubg led does not come on at all, you may need to replace that cord, or replace the whole adapter. You can replace just the plug, but it won't stand up to abuse as long as the plug molded into the cord will.

You are supposed to un-plug the AC adapter by pulling on it's plug that's plugged into the laptop jack, NOT pull on it's cord. If you tend to pull on the cord, which many people do, the plug or it's wiring at the plug will eventually be damaged, and after a longer time, the jack in the laptop can be damaged (if it is, the jack is probably loose (moves a bit) when the plug is plugged in and you wiggle the plug).

Laptop main batteries do not last forever - they tend to work as they should and retain their full capacity for about a year, then they begin to deteriorate and can no longer retain their full capacity.
Two friends have a HP and a Compaq laptop. The main battery was poor by the time the laptop was two years old, and the battery in both have since been replaced.
Laptop main batteries are known to sometimes short internally when they get older as well.

If your main battery is older than two years old (your model certainly is), you should probably replace it, especially if you need to run it for a max time on the battery alone frequently.
