If it's not the battery or the power supply cube, it may be a motherboard power component.


Also, if there are two memory modules try removing one and if the machine doesn't boot replace the first and remove the second.

^ Concur. Also could be the Bios has a setting that has changed and is now incompatable with system. You could try removinging the CMOS battery for 10 Minutes and if possible clear the CMOS. This is easy with a desktop, but a real pain in the A$# with most laptop as it requires dissasembly and the "Clear CMOS" jumpers are not normally identified in user manual - If they even exist. If you go this route, recommend just changing the $5 CMOS battery

Will this delete the stuff i have on hard drive? also i tried booting with one stick of memory removed and still same thing havent tried with the other stick removed though. I tried booting without the battery in. not sure where teh CMOS battery is i think it is right by the ram, are all laptop CMOS batterys the same or do i need to buy a specific one for the laptop?

(1) Clearing/resetting the CMOS will not delete files on the HDD. It may cause a boot problem if the default setting for the HDD is incorrect (ie set to IDE, but HDD was setup with AHCI mode. But if you can at least get it to post, then if boots alls well, If it completes a post test, but does not boot then just try changing the BIOS setting from IDE -> ahci (or visa versa).

The CMOS battery is normally one of the Watch type batteries, while many use the same one it is not a given.

To do this you will need to google "changing CMOS battery in dell inspiron xxxx (xxx = model) below is a link to the 3800 (note for this model dell calls it a reserve battery. For the 3800 it is no simple task, If your battery can be accessed from the memory module cover - great.

I think it looked like it was wrapped in a black cover the battery with wires coming out connecting ti to the board im guessing. So i pull it out wait about 10 minutes, replace the battery( i guess cut the black cover off) and then reboot and see if it starts up. If it does the same thing starts for 2 seconds then shuts off then i know it wasnt the bios? Could this mean i may have to get a new laptop? i dont think its worth sending it in for repair seeing as how they always charge an arm and a leg.

Did you try googling replacing it yet. Also how are you going to determine if the battery is good or bad. Normally if it is just low it only messes up time/date, but if "real" low it could cause the indications you have. Myself, I'd just use an Voltmeter and measure it. With the watch type batteries I just replace it, in the worse case I'm out 5 bucks. From what you are saying, it is not a watch battery, so you should either verify it's good, or replace it.

You could also pull the HDD and the DVD drive out, just to see if you can post - get an error saying no boot device found.

when i get home i will try to look at the battery maybe un plug it to reset the bios? then maybe remove the hard drive and see. or do the hard drive first.

ok just tried it with one stick of ram, then no hard drive, then undid the cmos battery for about 10 minutes, still all turned on for a second the straight off. could it be the video card?

Yes, except I think you have intergrated GPU (Not a Card). When it starts the post it is detecting a hardware problem which is preventing it from starting. Laptops are very hard to determine the exact problem because they do not lend themselfs to swapping parts in/out.

no, it's most likely power supply unit, it's not even getting to post, the laptop will still boot with a distinctive beep for video issues, or artifacts, or blank screen but stay on if video is issue, but for it to immediately turn off it's a power issue.

no, can't technically be change, the power supply powers the whole laptop, the power cord or battery just supply power to the power supply unit which distributes power to each component that is needed. Depending where you are and laptop repairs, it can cost as much as a new laptop to repair. Here it's about $175 for a new power supply for an Acer, and $75 hour to repair (at least 3 hours, have checked several places, long and delicate work).

sorry dude, but even if you have a place that does repairs and you go find out what's wrong, it will cost about $25 just for them to say power unit, Buy a new one.

Thanks for pointing me in the right direction - the CMOS battery was the problem for me. D620 laptop would power up for 3 seconds and then silence. A bit of a challenge to get to the 3 Volt "button" battery under the keyboard but a quick swap, replace all the bits and pieces (and all those tiny screws) and it fired up perfectly.

Voltage on the old (only 3 years) battery was 1.2 volts.

Total cost of repair = $4.00 (plus about 30 mins to dissasemble and reassemble)

You hit the nail on the head with the memory modules!! It fixed my problem. Thanks.

Guys, thanks for this.

I had the exact same problem after installing an SSD in my Aspire 5742.

Tried clearing the CMOS via the battery, no joy.
Removing a memory module allowed the laptop to boot with just 2GB - then shutdown and re-install the other 2GB.

Brilliant :)

Removing one module and start laptop again worked. Again I replace the removed module and started the laptop and it worked perfectly. Thank you very much. And also could you tell me what was the problem there? Will it occur again?

Mine powers on after a few attempts but the attempts are getting more and more now. Initially it was one attempt now its 2 or 3. will try removing the memory module hopefully thats the problem. Think it could be the CMOS battery as well coz i have had the laptop for 8 yrs now. That will be 2nd option. Think i will do a full back up first incase it dies.

Try taking out all the ram, the hdd, the cmos battery, and the wireless card as well as the battery. Put in just one ram chip and try to POST, if successful, add one item at a time and try to POST after each additional item. My laptop was having this issue and it turned out to be a power supply issue, I could only have one ram chip and the hdd installed to fully boot into the OS, anything more and it would freeze and restart continuously.

i have the same problem whereby my laptop shuts down seconds after its been turn on. I found the solution for it n i want to share it with u. it was BIOS battery problem. Take out your BIOS baterry and try turn it on without it. If things going well then you have to replace/change your BIOS battery. Its work for me.
notes: u can google how it s look like . Just type this "battery cr2032". most of laptop use this type for BIOS but maybe yours are different. u can buy at hardware shop.
Thank you

Happened on my Dell Latitude which is only a few months old.

I replaced the CMOS battery and it came back to life.

I just went down to Batteries + and got a new one. I ripped a piece of electrical tape in half (long ways) so I could wrap it around the rim of the battery to keep the - and + side connectors from touching. I used the other half of torn tape to wrap around the wire connectors to keep them on the battery after ripping them off the old one.

Hahahahhh ok, if the laptop turns off after a few seconds, something is most probably stuck in your fan, and as fast as the heat goes up, the laptop turns off to save the system. Simply blow some air in the opposite direction than the air usually goes

If it helps anybody, I had a similar issue with it turning on for a few seconds then cutting off. I swapped out RAM with no luck, but I noticed the length of time it stayed on seemed to change a little and got a little longer, so then I tried moving the RAM to the other free slot and it came on! I didn't try anything else after that, and I started there since I didn't know where the battery was. Hope this helps someone.

Thanks for the tips. You were all helpful. Inspiron 6000 had water spilled on it. It stayed on for a minute after the water was spilt on it. I arrived on the scene - pulled the plug and dried it out - for days. It would turn on for 5 seconds and not post.
After taking the keyboard off, HDD out, RAM out and nearly taking it all apart. I found this site. I checked the light indicators.
I swapped out the RAM with another 1GB stick - no luck. I was sure RAM wasnt it. I read these posts and went and found a 512 MB stick - original RAM. Works like a charm! Thanks so much!

I had the start problem on my daughter's Toshiba laptop. It works when I remove one of the memory chips but not with both of them in. I doesn't matter which chip I use just which location I set it in. How do I deal with that?
