I press the on button and nothing happens for a few seconds and then it appears to begin powering up - fan starts, lights come on - but only for a few seconds then it shuts off. There is no beep.
After several times repeating the process it will generally just start up as if there was nothing wrong at all. I have tried switching from battery to a/c but have found no difference.
I even put my computer outside the door in a cool place and the power went off. I noticed that it happened to me after upgrading the memory. I am wondering if that's the actual problem. I'll try again today after I take the new memory module out of the laptop to see if I can reproduce the issue.

Re: laptop wont start up
Sounds to me as though the unit is forcing itself in to shutdown. Could be related to an overheating issue or an actual hardware failure, but if the unit is fine after a few attempts, I suspect airflow issues in the fan. Check to see if the air port are blocked, and if you have some compressed air, clean it out.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.
it seems that you have damage memory card replacing may fix a problem but its better for it that you bring it to a technician in order to check much better because the motehrboard may possible be the problem.
May be there is a problem in the windows, but suppose it is not booting at all.
First Check once more your boot options from bios menu Second If it still the same thing, extract your battery out of your laptop for 12 min, then try to power up your laptop pluging in your power cable(don't use your battery) Third If it still not working, there must be a problem in your cooling fan, so check it, also check your motherboard & your graphics card (Most of this problems happens due to a problem in the computer cooling system in motherboard & graphics card)
Make sure your plugged in and the battery is charged up. Usually the laptop won't stay on for ten days because the battery needs recharging. Press the power button for about 5 seconds then try pressing the power button again to restart what happens?
We will see if the problem is due to the static charge accumulated on the laptop. Disconnect the power cable from the laptop and also take out the battery. Also, disconnect all the external devices attached to the laptop e.g. external mouse, keyboard, printer. Now keep on holding down the power button on the laptop for the next 30 seconds. Put the battery back and plug the power cable. Now try turning on the laptop and let me know if it works. Thanks!
remove battery and check if is charged. put back battery and connect power supply. keep ON button pressed few seconds until it flashes. if not started wait few second and try switching on normally. if unsuccessfully check both power supply and battery with manufacturer
