We turned the computer on and heard a series of loud beeps, so we immediately turned it off and unplugged it. Now we can't get the computer to go back on and the litle battery icon (above and to the right of the keyboard) is orange. The computer is totally dead. Please help! Thank you.
Take out all the CRU (Customer replacable Units) from the laptop eg: RAM, HDD, CD/DVD, FDD etc). Connect each one individually one by one and the start the machine.
Also, disconnect the Battery from the Laptop & Connect directly to the wall jack using the Adapter.
Also check for the Power port for physical defects, and if found have the port replaced by a certified technician.
Assuming that this is a laptop then it sounds like a few possible problems. Very common in laptops is a D/C socket problem. Even a Hairline crack were the power socket is soldered. This can be fixed try, www.laptoprepairspecialists.co.uk. Or it could be a problem with RAM. Depends how many beeps you were getting but a laptop will not boot without RAM. Any more help just ask.

At boot up, after the POST, each time the HDD led blinks, the laptop produces a loud "beep", and refuses to boot, as if this phenomenon prevented the HDD to be read.
If I press the power button, it stops beeping. When I release it, it starts beeping again.
If I press F8 at the beginning and then ask for a normal boot, It boots normally. Anyway, in windows, I have some strange activity, like I would continually pressing Alt+Tab. If I press Esc, it stops immediately and then all seems to work fine.
Is the computer completing post? This is indicated normally by a single beep after the power button is turned on. On most computers the beep is proceeded by a post screen with the manufactures logo. If the computer is not getting this far, unplug everything but the memory and video. This should cause the computer to give a no hard drive or OS error. If not pull all the memory, this should cause the computer to give a series of beeps (because there is no memory installed). If this does not work either, you could have a bad mother board or power supply.
I would suspect the power supply
over the System Board.
You will need a large antistatic
bag or antistatic mat plus a ground strap and a power supply checker.
Check the power supply using a
power supply checker (about $10.00). Unplug the power connector on the mother
board and plug the connector into the power supply tester. If you do not have a
power supply tester let me know how many pins are on the connectorand I will tell you how to test it with a
volt meter. If any voltage is not present, replace the power supply.If you do not have -5 volts it was used for
ISA slots and was completely removed from the ATX standard in 2004.
Do you have an onboard video
card?If you do is that the video output
you intend to use or a external video card?If you have onboard video connect the monitor to the onboard video
output. Disconnect the AC power supply cord from the computer and attach a
ground strap from your wrist to the bare metal of the power supply. The down
side of static damage to components is you do not always see the damage
immediately since static can weaken components causing future failure. Remove
all cards from the slots except the video card if you do not have the onboard
video. Be careful to touch only the edges of the boards not the connecters and
place them on the antistatic mat or in the antistatic bag.Plug the power supply back in and see if the
Power On Self Test (POST) displays the boot process on screen or beeps are
audible. The error beep codes can change from the BIOS types but these are a
few generic ones.It would be best to
check your motherboard manual for a complete listing of error codes.
1 short beep – System is OK
No beeps – Bad power supply or system
Continues beep – Memory error
1 long two short beeps - display
If no video is displayed and no
beeps can be heard, turn the system off by holding down the power button for 5
seconds then unplug the unit. Verify the ground strap connection on your wrist
and the bare metal of the power supply.Carefully remove the memory sticks handling only by the edges noting
which slots they go in and which module was taken from which slot and place
them on the antistatic mat or in the antistatic bag.Plug the power supply back in and see if a
continues beep is audible. If yes, power off the unit and unplug the power
cord. Put only one memory module in the first slot but do not put the same
module in the same slot (swap them) if you have more than one module.Restore power to the system and see if the
continues beep is no longer heard and you see video.If you see video and no continues beep than
power the unit down and unplug the unit. Do the same for any other memory
module which will help you determine if any modules are bad. This test is not a
complete test but if any modules are dead you can identify them. If no video
and no beeps the motherboard is the suspected problem.
If you have video and one short
beep upon power on and all memory checks good.Power down the unit and unplug the power to the power supply inset one
of the removed boards and try to boot the system to see if you still have
video. If you do power the system down and repeat the same procedure for each
card. If you do not have video suspect that card is bad.
Good luck and be careful to always
touch the bare metal of the power supply with it unplugged before reaching
inside the computer and touching any boards.
I just had the same problem to deal with. My computer automatically turned on, and just when you thought it was gonna work, there was a single, loud beep. I immediately unplugged the computer. Make sure all the cords and chips are properly and securely connected. My problem was that my memory cards were loose. Maybe that'll help.
Hey there aj1253, It seems you are getting power to the board. are the fans running?Are you using onboard video or video card. Onboard is suggested for test. I would also suggest you reseat your ram. That is removing it and ensuring it seats properly. Beyond that I would ask you provide more info ( ie is this a new build, or did it just stop working, configuration details, model #'s, et....)
make sure you have seated all the cards properly, take them out and reseat them including the ram. Make sure your IDE cables are plugged in properly as well. Restart the computer and if still no post then yes unfortunatly for you its the mobo =(
