Mother board post

Comment by Theocanj, posted on Apr 30, 2008The CMOS battery is the round battery on the mother board, correct? If so, I replaced it and still nothing. I guess I should try replacing the power supply now as well and perhaps both of them being new is the answer?

Yes, if replacing the cmos battery does not solve it, then maybe the power supply also is faulty.

How to fix this problem ?

First, if you're using DDR2, then you'll need to make sure the RAM sticks are paired, for example if you have 1GB RAM and it's DDR1 2 or 3, then most likely you have a pair of 512MB RAM sticks. It seems your POST is having an error, POST checks for things like keyboards, mice, drivers, and BIOS, as well as RAM and CPU. If POST finds an error in something like the CPU, fans, BIOS, RAM, or anything crucial to the boot up, it will shut down. Otherwise your CMOS chip is fine, really the only problem that may occur is yours CMOS battery may not be charging, and in that case you'd just have to replace it. You also should always wear an ant-static wrist strap before working on computers.

Power in intel mother board 845gvsr,but has no display.processor,ram is ok,because its has been tested on different mother board.

Your should test your PSU also. It doesn't mean that when the power is present and all of your system fans is moving is that your power supply is OK. If your PSU is a generic one i will give a second thought that you should test your PSU in another working unit or if you simply have a multitester you can check the terminals while the system is on and could get readings accurately without any drop in voltages.

If you are really sure that your mobo is the problem then do the following if it will work for you:

Most motherboards nowadays don't work at all if the CMOS (Complementary Metal Oxide Semiconductor) battery has emptied out or weak, remove the battery and test it with multitester, a good battery is about 3V or slightly higher, a 2V reading or below would post a serious problem on the CMOS program of the motherboard which may post a problem in booting. If you find the battery is weak replace it with a new one. If these steps doesn't work at all then you should look for other problems. Observed any bulged capacitor where the upper cover is slightly push upward and remove them if you find one using soldering iron and replace it with a new one with the same rating, but if you can't find one just try removing the motherboard from the main system unit, remove the CMOS battery and clear the CMOS for about a minute or more. You should drain any power left from the motherboard's capacitors that keep supplying the CMOS chipset. You could use an aluminum foil to shorten out all the circuits under the motherboard to drain the circuits out. Draining the circuit simply putting the system on all default position. After doing this you can now put on the CMOS battery, put back the CMOS jumper setting to default and inserting all the components for testing.

Hope it helps because most of the time it works except when the regulator IC is really a problem.

Self test screen on monitor; pc power on but no response from keyboard.

Friend!! please ensure that all the cables are fixed well or once again remove them and put them again. Change the CMOS battery with new CMOS Batter which is essential to run POST. Check the VGA Cable (Monitor's) to the mother board or video card!! Restart!! your problem will be solved!!!!

You have a corrupted bios file or files. This is what the checksum means. You need to download the correct bios onto a floppy disk. That floppy disk needs to formatted as a system / startup disk BEFORE you copy the bios files to it. Then put the floppy into your floppy drive, turn the pc on and try to get into the bios screens. If the keyboard error is preventing this, go to the mainboard manufacturers website and check the correct manual for the board looking for the procedure to recover from a bios failure. If this board if no older then 5 yrs, it should have this feature. Follow the recovery procedure to rewrite your bios. When that is fixed, undertake the bios update procedure. ONLY do this if you fully understand and accept the risks otherwise, take it to your local professional. If your board does not have the recovery feature, replace it !!unless you are able to replace the CMOS chip with one which has the correct bios burnt onto it. As most modern boards have CMOS chips glued and soldered to the board, this may not be an option..If the bios chip is socketed, contact your local computer shop, or the boards manufacturer to request a replacement. Your issues all arise from your bios issues so fix that and all should be well..

Mercury motherboard pi945gcm cmos setting dose not save shut down machine then power on machine see press f1 date & time not save

This sounds like your battery may be bad or not locked into place fully. Also on the mother board there is a cmos jumper that is used to clear your bios check to make sure the jumper is set correctly an also inspect the jumper to make sure it will make good contact to the jumper posts. Good luck I hope this helps. Also when you set the time in your bios make sure to exit with f 10 key or whatever the save and exit key is for you bios.
