Low cmos batt would cause a system not to bootup?

Postby cas » Tue Apr 07, 2009 1:22 am

Or having a blank screen? Anyone can confirm with me on that? Cos recently i went to service a pc which has distorted image and turn out the graphic card is spoilt, at the same time i notice the clock keep on going back to default though i've tune the time to exact and twice i reboot the time would go back to default thus casuing me to suspect it could be due to low cmos batt but then would a low cmos batt cause a pc not bootable as in blank screen?

The other possibilties could be i change a ati 9550 without installing the drivers as i forgotten to bring the drivers cd along. Anyone can kindly. Fyi it was working fine for a few day after i service the pc and now i was told it wouldn't boot up, i suspect high chances the cmos batt is causing the issue but am not too sure.....

It could be that any changes to the BIOS are not saved, so settings like "Init display first" will not be correct. Easy enough to get a new battery and see if it fixes things, eh? ;) Chris.

Latest update, i've went down yesterday and try all means till finally i managed to find the culprit which is a failing fused inside a 3 pins plug. Hmm i wonder why would all of a sudden the amplier fused burn? Though i did replace the cmos battery which is oso prompting cmos error

My initial impression is could be due to the multi plug adapter which has 3 pins/female on top, two pins/female infront, as well as 3pins/female below that they are using, as they plug all those plugs be it printer, pc, monitor, fans and intercom all under one multi plug adapter instead of those multi plug extension. Say maybe voltage overload or stuff that causes the issue?

Btw can a 5 amplier fused use on a 3 amplifier fused 3 pins plug say if i just swap the fused? Excuse my ignorance as i'm not electrical trained

You mean, there was a 3 amp fuse in the 3 plug adapter, and you want to put in a 5 amp fuse? Should be fine. The 3 amp fuse would blow very fast if too many high amperage devices were plugged in at one time.

Strange they would put a fuse in one of those adapters anyways. None that I have ever seen here in the States has fuses. They just plug into the wall and you plug 3 things into it.

Personally, I like the big 6 outlet plug strips, with a 3 foot cord, you plug into the wall and then you have 6 outlets. Mine all have built in surge supression and a 15 amp circuit breaker. Chris.

i have a UPS or a interruptible power supply from APC 1 for each system i have. the biggest is 1500VA or volt amps it has enough battery life for my main rig for about 18 minutes of play time lol!! while the other which is a 875VA it has about 45 minutes of game time but it has a lot more plug into it. it has the modem and router plug into it. since it is my server box so i need it to stay on as long as possible. but both are coming up on life of the batterys so i need to figure out what to do with them. since A they cost all most as much as buying a new 1 and B im broke lol

but yes go to a store and get a surge protector strip instead of those junk plugs thing you have. the better it is the better the warranty it will have. since some will have that. if it is strike by lighting or a electrical surge it could be covered. while your thinking nah my insurance will take care of it. well dont be surprised when they tell you. well since you didn't add it to your coverage its not. its now a add thing so its no longer a freebie. which is something i got coverage to. since i have so much invested in my sets ups.

beside its nothing like playing when you notice your house and everyone around is dark and your still online and playing!!

Surge protection ---YES at all costs.
I do not know what brand of battery backup you are using but the APC line has replacement batteries and or has taken a trade for different unit at far less than the original cost

APC are the ones i am using right now. but there price for replacements are all most the same price i could buy a all new unit for right now. they need to come down on the battery prices even with there so called trade in. thats is one of the big things i have against them,and that when my power lines outside my house caught on fire. 3 times about 2 yrs ago.

for some strange reason both psu in both of my pc got hurt but not the APC units. and they did not stop my pc from getting damage either. that made me upset since that is one of the reason why i spent this kind of money on these units. is to protect my investment from electrical surges and stuff like that from happening. they did say they would pua for the replacement. but i said they were both under warranty so it was good over all.

i just wish i had 1 on my TV now back then cause it took out my nice Magnavox 32" flat CRT which was 2yrs old man i was sooo p1$$$$ i still like to get one of there cheap units to put back there for my house entertainment system so that way its all protected.

I only need 2 good UPS to connect to my generator. That way if power goes out I can run the TX, my computer, the cable modem and a heater :)

Ive seen a few UPS that have USB connectors for the computer to monitor and shutdown schedule of the computer...Ive also seen this same setup cause problems with bootups. Ive often wondered if that same setup couldnt cause a backflow of power during a problem that ould also do damage.
