Your computer might emit a series of beeps
during start-up if the monitor cannot display
errors or problems. The following repetitive
beep codes help you troubleshoot problems
with your computer.
NOTE: To replace parts, see the Service
Manual on the Dell Support website at
One beep - BIOS ROM checksum failure;
possible motherboard failure
Contact Dell (see "Contacting Dell" on page 53).
Two beeps - No RAM detected
Remove the memory modules, reinstall
one module and restart the computer. If
the computer starts normally, reinstall anadditional module. Continue until you have
identified a faulty module or reinstalled all
modules without an error.
If available, install memory modules of the
same type in your computer.
Three beeps - Possible motherboard failure
Contact Dell (see "Contacting Dell' on page 53).
Four beeps - RAM read/write failure
Ensure that no special memory module/
memory connector placement requirements
exist (see the Service Manual on the Dell
Support website at support.dell.com).
Verify that the memory modules that you are
installing are compatible with your computer.
Five beeps - Real Time Clock failure
Replace the battery.
Six beeps - Video BIOS test failure
Here are the beep codes for the Thinkpad:" Continuous beeping System board failure One beep; Unreadable, blank or flashing LCD LCD connector problem; LCD backlight inverter failure; video adapter faulty; LCD assembly faulty; System board failure; power supply failure One beep; Message "Unable to access boot source" Boot device failure; system board failureOne long, two short beeps System board failure; Video adapter problem; LCD assembly failureOne long, four short beeps Low battery voltage One beep every second Low battery voltage Two short beeps with error codes POST error message Two short beeps System board failure.
Beep codes vary but 1 long and 2 short usually indicate a video problem. Since your problem began with removing the ram try this. Remove the memory modules again and re-seat firmly. If you notice the memory channels are dusty blow them out before re-seating. Hope this solves your problem.
Continuous long beeps-RAM error 2 short beeps- BIOS error 1 long and 8 short beeps- Display Card error 1 long beep after few seconds 2 short beeps-FDC error 1 long beep after few seconds 1 short beeps-FDC is Ok 1 long beep and 2 short beeps-Display Card Error
Most probable cause is Ram memory, please try removing modules and reinserting, also try using alternately just one of them to determine which one is defective.
One beep means everything posted right
I would start with the video card and pull
it out of socket then reinsert it you could
have a bad card or bad cable or the
mother board cant handle vcard
Short, No power, Bad CPU/MB, Loose Peripherals
Everything is normal and Computer POSTed fine
One Long Beep, One Short Beep
One Long Beep, Two Short Beeps
One Long Beep, Three Short Beeps
Three Long Beeps
Repeated Long Beeps
Continuous Hi-Lo Beeps
Exactly how far does your computer get before it restarts? there is normally a short beep during the startup phase, do you hear the short beep, or is it a long beep or a combination of different beeps?
I am not saying that it cannot be the power supply but usually problems of this sort are a faulty graphic card or faulty RAM, worst case senario is a faulty motherboard. The first two you can test by adding an extra graphic card or replacing the RAM (or taking one out and then the other if you have more than one RAM) - BE AWARE that you can damage your computer or the RAM itself if you touch the wrong things and you are have a static charge.
Based on the information provided, looks like some peripheral or component failed. This abnormal beep means some components (like RAM) is either not functioning OR is loosely connected etc.
If you are comfortable with your desktop, i would suggest >>
(1) checking if the RAM modules are inserted properly or not.
(2) Checking if the Video card is inserted properly.
Sometimes RAM/video card etc get loose due to a shock/**** etc, and hence the abnormal beeps.
If you are not comfortable with opening your desktop, then i am afraid you would have to call for service to check whats wrong in the system.
Thanks and do tell if this solved your problem.
The 1 long 2 short beep code means a problem in the video circuitry and the laptop can't initialize the display. This is usually caused by failure of the integrated video chipset. Unfortunately, on a laptop you can't just open the case and install a new video card like you can on a desktop. You need to replace the mainboard. Replacements are available online. Here is one source found by a Google search. (I'm just using this as an example. I haven't dealt with this site.)
The 4 beep code means no memory detected when the computer started up. No surprise there since you had taken it out.
