Yeah, if you put it back together exactly as it was with the old memory stick and it still doesn't work then something must have been damaged when you were putting the new stick in. Or the memory stick isn't in all the way. Not much else it could be.

Can you get more specific with your model? CQ62-215? 220? DX? SA? There are a ton of CQ62 models. That will help with the specifics, also the exact crucial model number.

Once we have that info, can provide specific details on how to swap memory for that laptop, etc. Just want to confirm that you turned your laptop off when replacing the RAM? Unlplugged from wall and removed the battery?

OK - when you put your old RAM back (while the PC was off, battery was out and AC was not plugged in), did you put the RAM stick back in the DIMM0 slot? Did it have anything in DIMM1? When you installed the new memory, did you install both sticks of RAM or just 1? Are you going for a total of 8GB?

Next, what happens when you power on your laptop? Do the lights come on it? Does it show anything on the monitor at all? \

Clean the edge connectors of the RAM (old first) with a pencil eraser. Oxide on the edge connectors can cause issues when RAM is disturbed.

Always pop back and let us know the outcome - thanks

That normally means general system board failure. The CPU / RAM are tied closely with that though. I would suggest like Derek suggested, to remove the RAM and clean it, then reseat it carefully and attempt to get it to boot.

The new memory should work with your system, was there a tough time getting it in? Any force applied to get the ram in place?

You may want to try a hard reset to see if you can get it to show anything:

Disconnect all peripheral devices and remove all USB devices and media cards.
Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
Reconnect the AC power adapter (but do not connect the battery), Press the Power button. Does it display anything now?

Nothing. I will probably have to take it to an expert.
Thanks for your help.

"Does it show anything on the monitor at all?"
What is the answer to the above question (from #3 response)?

Unless you plugged the RAM in and out with the power on then most likely you have disturbed some connector somewhere. Check all connections for tightness before you spend money on getting it fixed.
EDIT: Don't rush to give up just yet!

No it never showed anything on monitor. This is only my 2nd laptop to change memory. The first one went so smooth. this wasnt that smooth. the first card wasnt' easy to put in. if I somewhat forced it in. Nothing major- what will that do to it?

Just thought of this..
One thing you could do is remove the RAM from the system completely. If you get the same CapsLock blinks, and the motherboard doesn't beep, likely have a bad motherboard. Could be coincidental that this happened at the same time.

If you get no lights or different amount of blinks, or it does beep, at least you know installed the RAM properly and its likely some type of other issue.

EDIT: Still may be a good idea to take it into a local IT shop though.

If you never see anything at all on the screen then that confirms it is a hardware issue (not much of a surprise obviously). It's difficult to explain the effort required to insert RAM. It has to be a firm push but not a monster effort. Could be a damaged socket I suppose.

If you are sure all connections are firmly in place then maybe hands on help is necessary, as you said. Sounds like a bit of a coincidence that it happened after the RAM was changed but I accept that coincidences can sometimes happen.

EDIT: Fixed typo
