It's usually behind a removable panel on the back of the laptop. Usually, you'll see small screws holding the panels on. See if you can remove the different panels and see what's behind them.

Normally the manufacturer's don't bury the CMOS battery too deep in the laptop so that it is easy to replace.

....but as u can see the cmos is underneath the front cover so in order to get there i must disassemble the laptop very careful..and see if that works.. Anyway thanks for your comments.

What type of memory are you putting in?
The laptop itself supports one type PC2 4200 200PIN DDR2 SODIMM

He said he put the original RAM back in the laptop and it still won't work, so he's got a bigger problem now. See FIRST post.

One tip if you DO decide to do the disassembly...get an empty egg container or, in my case, I have a number of those plastic pill boxes with hinged lids, they're even better because of the lids.

Number the compartments, and place the screws and/or parts in the compartments in sequence during disassembly. Then reverse for re-assembly. Lots of screws in a laptop case LOOK alike, but might be of different lengths or thread. Be patient and move slowly!

You can also try remove the main battery leave it out wait 10 minutes then plug in the power cord (with battery still out) and see if it will power up. (Have had that work with several non booting acer laptops)

Amen regarding the screws. You get a bunch on the table and it's like - uhhhh..... which one goes back in which hole. That's why I hate working on laptops - or just one reason.

WOW I am overwhelmed, I am subscribed to many forums but this is the first time I get so many replies in so little time ..Thx all of You guys .. Well to the point,,
The new memory is kingston(kvr667d2so) 2 stick of 1 gb each. DDR2 PC2-5300 (667MHz), compatible with PC2-4200 and PC2-3200, my friend bought the memory at microcenter where he was told that this should work even if the original memory was 512MB DDR?.But I checked the site of Kingston and the model(KTT533D2/1G) they recommend is different.Now my question is this ... if the new memory is not compatible with the laptop this could be the reason for the death of the motherboard if the mobo is dead(i hope not)???...
Again thanks for all your replies

I've never seen the wrong memory kill a motherboard. Normally it just won't boot. Putting the old (correct) memory back in usually restores function WITHOUT having to pull the CMOS battery or anything crazy.

It could be a coincidence or something really bad could have happened.

Do this - pull out ALL THE MEMORY and boot the laptop. IF the motherboard is OK, it should give a beep code basically saying "hey - I don't have any memory".

If not - the mobo might be toast.
