How can i fix my IBM ThinkPad T22 2647. it produce 3 simultaniuos beep sounds lcd is black out.


This is a list of ThinkPad Beep codes.
It appears you have a memory or motherboard problem, most likely a RAM problem. Try reseating the RAM modules, if this doesn't work, then remove the RAM and take them to your friendly computer repair shop to get them to test the RAM modules for you. If the RAM is faulty them replace.

At start the computer - 2x beep - what is that ?


Here is a good link I found on the web. You can click on link below.
Also I found Beep Code with descriptions. If you find this helpful, please rate me.

http://en.wikipedia.org/wiki/Power-on_self-test

I think a few OEM's have developed their own or use Phoenix or AMI beep codes, but for the most part motherboard manufacturers uses the IBM based ones because they are grandfathered in. Beep Code: Description of Problem: No Beeps Short, No power, Bad CPU/MB, Loose Peripherals One Beep Everything is normal and Computer POSTed fine Two Beeps POST/CMOS Error One Long Beep, One Short Beep Motherboard Problem One Long Beep, Two Short Beeps Video Problem One Long Beep, Three Short Beeps Video Problem Three Long Beeps Keyboard Error Repeated Long Beeps Memory Error Continuous Hi-Lo Beeps----------------------------CPU OVERHEATING
---------------------------------------------------------------------------
On the forum link below says Ram. Read on.
http://www.help2go.com/forum/computer-help/101730-post-cmos-error.html

The meaning of beeps at boot depends on the BIOS that is installed. This will give you an idea, but my guess is you have a RAM problem. Try checking that it's properly seated, otherwise you could run a program like Memtest to confirm the problem. Pls rate me. Thanks and Good Luck.

No display .. getting three short beeps, pause, one shot beep, pause, four short beeps, pause and another three short beeps.


It's the sound produced by motherboard stating that motherboard is not able to detect the RAM,open the laptop and remove the RAM and clean with a white paper slowly and insert it properly.check it solve your problem otherwise if you have another RAM slot available then try that too. if none work replace with a NEW RAM this will solve your problem

let me know if it's helpful to you

My pc not working and gives 4 beep only


Most probably, this could be a videocard or memory problem.

Try opening your CPU and take out the memory and place it to a vacant slot. Make sure it is properly installed.

Do the same also with your videocard.

If it does not work, try isolating the problem isolating the problem. If you have extra memory or videocard, it is best to do trial and error by replacing one at a time to determine whether the memory or the video card is defective.

Dell 8400 is not starting


Check if the RAM is seated properly and clean too. Check your power supply(SMPS) for the 3 voltages it should generate. RAM will not need any replacement however your SMPS may require replacement...sodeep

Laptop not working


It's possible that the motherboard has a problem and needs replaced. However, usually when this type of thing happens, it's with the memory, battery, or hard drive. A failing memory chip or malfunctioning battery are the two main causes for this. You can check these yourself by; 1- removing the battery and starting with the power suppl only, 2- removing the memory and try starting with one chip at a time, 3- remove the hard drive and see if the machine will go to the initial display screen. If these three don't work, then I'm afraid the problem is with the motherboard and it will need to be replaced. Unfortunately, HP has the most fragile and rather pricey motherboards on the market, so the problem may very well be with the board. If it is, take into consideration the cost of the repair and the cost of a new machine, it may be time for a new laptop.

According to the support website, it could either a memory (DIMM) or motherboard (System board) problem. See beep codes and what them mean here: http://www-307.ibm.com/pc/support/site.wss/MIGR-46018.html

First thing to do would be to remove the memory and put it back in (called 'reseating') to make sure there is a firm connection to the motherboard. Find out how to do this for your particular model here: Click here. If you have two memory modules installed and the remove/reseating action did not stop the beeping, try removing just one and attempt to boot the system.
  • If you get the same beeps again, remove the one you have installed and replace with the one you took out - try booting.
  • If you don't get the same beeping and you can then boot in to windows, then you've identified the bad memory module. Replace it.
If you still get the same beep code, then it sound like it's your motherboard that needs to be replaced.

Problem of motherboard


Could be a power supply fault, motherboard fault, or fan fault. Many new motherboards will not power up if the fan doesn't rotate, to prevent the processor getting fried.
