I have one of these to repair where it powers up then spins the hard drive briefly and then nothing. It charges the battery and the power lights remain lit but the screen never fires up.
I am trying to reset the CMOS as nothing is visably damaged. Oh and if anyone wants to do this then you need to remove the motherboard from it's bottom casing to get at it. There's no other way!
Will post a new reply if it solves the problem but I reckon it's a long shot.
If anyone else has any ideas please let me know.
This happened to me on my Acer Ferrari 3200 once. The problem was that it had some kind of spyware days before this happened. My brother inserted a Windows XP cd to try and reformat the computer. A few seconds after inserting the disc the BIOS screen came up and he restarted the computer and worked fined after that. He did not reformat the computer, he only inserted the disk into the drive and that was it. Now I am having problems because I guess I got a virus and when my brother fixed the screen problem, he does not remember if he put in a password. Well, now it is asking for a password that is 8 characters long and he does not know the password neither do I. Does anyone know if removing the CMOS battery for 10 to 15 minutes works? I heard that removing the CMOS battery clears some of the settings including the BIOS password, has anyone tried it before? If so, did it work?

Re: CMOS Battery Removal
First, you should find out how did this happen in the first place.
Then, check the processor :). It is your main concern. Remove it and try to power again to observe if any difference. If none, that should worry you. Then check all connections between diferent boards to the main board, a faulty connector isn't unusual. Reseting the CMOS memory woun't do any good I supose, because it is NAND ROM type and most of it's settings are resident into this area. For example if you set a password, you woun't be able to clear it by reseting/removing the battery to the BIOS or something like that. This is a security feature that comes with most laptops.

Unfortunately, that sounds like a motherboard problem. Blown Capacitors will do that. If you know how to open it up, you can peer inside to see if any of them are blown or bulging. Repair can be cheap or expensive, depending on your skill with a soldering iron. Hope it's something else (could be a bad connection from the AC adapter plug).
yeap....itz the main/mother board.. do it only if u r a professional.. disconnect ur system from power mains..open the cabinet.. replace the cmos battery (+3v; type: 2032 probably) on the main/mother board..connect to the power n boot, enter into cmos setup utility (by briskly pressing DEL/F1/F2/F10 as applicable)..set the time here..save n exit n restart..see if itz rectified..
if not probably the board is damaged, if u r a professional check the
capacitors(above 1000mfd) n mosfets, check for the circuitry around
south-bridge.. contact ur system admin/vendor....
Forgeet the CMOS battery, worthless exercise.
Most likely from what you describe it is a bad motherboard, and on a system that old I'd say replace not repair.
If you want to fix it, mothebroards are $50 to 100 for that model on EBay
If you're not ready to take it to a repair shop, there are a few things you can look for yourself. If the power blinks for a quick second before cutting out, which means you most likely have a short. This could be as simple as a faulty power cord, so try moving the cord where it takes the most movement, to see if you can get prolonged power by holding the cord in certain ways (temporarily making the worn wire inside make contact) If that does nothing, take a look at the mainboard itself. Look for any darkened or discoloured areas, or melted/damaged resistors etc.
This could be a Power/Switch Problem.
Solution:- Leave the laptop turned Of And charge the battery to Full Capacity. ( usually between 4-16 Hours ) depending on capacity.
This will also fully charge the CMOS ( memory battery )
then boot the laptop up, and see if this solves your problem.
If not i,d suggest running a scandisk or hard-drive diagnostic program, to ensure that you have no Viruses-bad sectors on the hard-drive.
If you need further assistance please don,t hesitate to ask for more help and advice.
Mike @ Compurepair.
I suggest removing the battery when plugging it to the wall outlet or are you trying to charge it?
I think the one that is spinning is the hard drive reseat it then lets see what happens
try to purchase a new hard drive if problem persists. please indicate also the status of the lights on your laptop ill reply with more steps when you've indicated everything
