The green light on front of my HP computer comes on for a couple seconds and then it goes to red light blinking and beeping try to turn off and back on several times and go right back to blinking red


test all leads that attach to your hard drive including electrical extensions SATA

the leads from your (motherboard to your hard drive) make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty


make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty


even something as small as an electrical extension or a faulty fan lead can cause you problems computer needs all of the data and power to travel through every working device and to have an end for a computer to be able work properly


a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all electrical extensions make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working


check the CPU make sure it has thermal paste and dust free secure seating


also check your computer ram modules and cmos battery make sure they are dust free and securely seated some motherboards cmos batteries are soldered in


hope it helps

My dell dimension 2400 will not boot up. It goes to a black screen and displays either keyboard failure or F1 or F2 options


This can usually be solved by resetting the CMOS.
Unplug the power from the back of the tower. Open the side of your case and locate the round battery near the lower-right side of the main board. Pop the battery out. Just below it you should see 2 little gold colored pins sticking up. Right around it it should say 'Clear CMOS' in very fine print. Take a small screwdriver and hold it to the two pins so they are shorted or touching each other through the screwdriver for a few seconds. Place the battery back in the machine and see if this works.

I have a compaq armada but dont know the power on password how can i fix


Try this remove the main battery and mains power supply, hit the power switch to drain any retained charge. then remove the cmos battery. The cmos battery is on the right under the panel at the top of the keyboard, which can be popped out by gently levering it up at the edges. the key board can then be folded clear, watch for the ribbon cable under it that connects to the motherboard.no other way i know of. You might want to check this location first get to the cmos battery via the removable panel on the bottom right front of the case (other side from the battery). first remove the main battery. next remove the panel, under it you will see a modem card, remove the modem card and you should see the cmos battery to the right side its loke a big watch battery. there will be a connector on the wires going to the battery. remove this to disconnect it. now just push the start button with the machine un plugged, just to discharge any residual power. wait a couple of minutes then reconnect the cmos battery then the modem card, then the main battery. plug it in and start it up. the screen will come up with something like "cmos bad checksum, defaults loaded" do not worry this is normal. if it doesn't start normally, switch it off by holding the on button down until it goes off then restart. it should be fine after that, password gone. you can then get into your bios and set it up to your liking. I recommend not putting in a password. Let me know if this works for you.

IBM t42 comes on, beeps twice and goes off, connected and battery


Yes it is the fan, get a can of compressed air and clean the air vents and the CPU fan with that, also i would check into the CMOS battery as it could be dead and needs replacing.
As the laptop starts up hit F1 when you see the IBM logo and check the date and time, that will be a clear indicator IF the CMOS battery is dead because it will not be the right date and time, it should however let you into windows if you put the date and time right (it may take a couple of attempts)


Good luck

Change Compaq V6120us cpu battery


I believe that the cmos battery for your particular laptop is located under the keyboard. You must first remove the plastic bezel between the F keys and the monitor hinges. See if there is a little screw from the back that goes through the hinge covers. If so, remove them. There should also be 2 screws underneath the battery that goes to the center of the bezel. Remove these.

Now you can use a small object (tiny screwdriver or the like) to pry up one corner of the bezel, and it should pop right off. There are 3 or 4 screws just above the F keys of the keyboard that have to come out. Slide the keyboard towards the hinges, and it will come out. Carefully remove the ribbon cable from the motherboard, and remove any cover that is there. Walla, the cmos battery should be right in front of you now, so go ahead and change it. Reassemble in the reverse order of disassembly.

CMOS error - defaults loaded.


It is possible that your CMOS battery is low or dead.It retains the memory power to the CMOS when you turn off your computer. Change it and see if you problem goes away. It's a round silver disk.They are sometimes called coin batteries because they look like a coin. They come out easy and your local Radio Shack or Batteries Plus will have them.
