Can you tell if your AC power cord is working? (Is there a light on the computer that comes on when it's charging?) If the power pack went dead, your battery could've died and now you get no power to the PC which is why it won't boot up.

To test, take out the battery and plug the AC cord in and try to boot up. If nothing at all happens without the battery, then your power cord or power pack is dead, and you just need to replace it.

Shut down automaticaly


Not much to go on, "shut down automaticaly" on battery or AC or both? A computer will shut down, or hibernate, if thats what you mean, that's a power setting? If a computer overheats it will shut down automaticaly to save the components from heat damage. If there is dust in the fan and vents it will shut down. If it is not getting sufficent air flow from vents on the bottom of the laptop through the vents on the side. One option is a Laptop Cooler.Is it shutting down when you are on it? When it's left unattended? Respod to this post for further assistance.

Battery was fully charged on my hp nc6400 i shut it down and sat it aside, i noticed the battery light contuniously flashing, i hit power and nothing happens.


Dead battery, how old is the battery, Is it a replacement? Do you remove it when on AC for a long time? Test battery, replace if necessary. I never leave the battery in if I am on AC, say at home, and NEVER leave a laptop unattended and plug in with battery in when not in use. A faulty battery is a possible fire hazzard.

Hi, you can download a manual here:

http://www.abit.com.tw/page/en/motherboard/motherboard_detail.php?pMODEL_NAME=AI7&fMTYPE=Socket 478&pPRODINFO=Manual

The fault could be the cpu, wrong type of ram, a faulty ram module
or a fault in the mainboard.
Check all the settings in the manual and the bios aswell.

Here is a list of beep codes:
Basic Beep Codes for ABIT AWARD BIOS Motherboards

  1. No beep at all - this means your motherboard is dead, either due to a defective or underpowered power supply, poorly seated CPU or RAM, or a dead-on-arrival board
  2. One beep - board is working fine
  3. One long beep then machine shuts down - faulty, improperly installed or missing CPU
  4. 1 short(Beep) System booting is normally
  5. 2 short(Beep) CMOS setting error
  6. 1 long - 1 short(Beep) DRAM ERROR
  7. 1 long - 2 short(Beep) Display card or monitor connected error
  8. 1 long - 3 short(Beep) Keyboard Error
  9. 1 long - 9 short(Beep) ROM Error
  10. Long(Beep) continuous DRAM isn't inserted correctly
  11. Short(Beep) continuous POWER supply has a problem
  12. A two-tone siren, generally caused by overheating or out of specification voltages
  13. Four beeps then machine shuts down. This is because this version of the BIOS will shut down your machine if no fan tachometer signal is detected on the fan header. Make sure you attach a fan to the FAN1 or FAN4 header or clear CMOS to reset to default (no checking).

My compaq presario sr1000 computor won't stop beeping from the inside and it says no signal on the monitor


1 short beep and 1 long beep means its a memory problem.
Shut down your computer, then open your computer case and replace the memory module.If you have 2 or more modules ,try starting the pc with one.If it fails, try a different single module.

2 short beeps and 1 long beep repeating for 5 times means its a graphics card issue.
Shut down your computer, then open your computer case and unplug the graphics card, then plug it again.If this doesn't help, try with a different(confirmed working) graphics card.

Hi,
Try running the diagnostics on the computer. You may need to repeat some of the steps that you have already done to initiate the same.

1. Remove the battery and the Ac adapter from the system
2. Press the power button for 10 seconds
3. Reinsert the battery and connect the Ac adapter
4. While holding down the FN key on the keyboard press the power button.

If the system beeps in a series on 3-3-3 or 3-3-4 the system is ok and there could be a problem with the screen.

If the system beeps in some other code . revert to the post and we would let you know where the problem is .

How to unlock the lock computer?


if you forgot the password then there's no choice but to shut down the laptop.
You must shut down the computer first. Turn it on, and repeatedly tap F8 and enter safe mode. From there on, click on administrator, and when Windows loads up, click Start> Control Panel> User accounts> Choose an account> remove password.

Hope this helps . . .

When powering up I get 2 short beeps and one long one.


The beep code is signifying either improperly seated/ bad ram or improperly seated/ bad video card. Since you replaced the RAM I would say it would be a bad video card. Replace & reboot. Hope this helps & please remember to rate my answer. Thanks.
