My notebook will not power up at adjectives but the lead on motherboard is on. can cmos battery-operated affect this?
Answer:
Bios is not held in the battery-operated. Could be a bad power switch. Just a desperate bios batt shouldn't keep your notebook from starting, it just wouldn't hold a date or time, but it would do SOMETHING. As okay as the power switch, could be the power supply too. You can also try re-seating your memory, sometimes that helps as capably. But it's probably the switch or the power supply.
I have see dead power supplies in the past with LEDs that night light the motherboard. A power supply has +5v -5v -12v +12v, losing one of these can distribute you the type of problem you are experiencing. But still light the LED on the board.
yea the mobile could be the problem. just check your connections previously exploring the battery preference! However, it does sound similar to the battery.
could be the CMOS mobile but they can last a suitable 6 years easy.
I would verbs all the PCI cards out, re-seat the RAM, check adjectives connections and disconnect the hard drive and see if you can boot to a floppy
The small freestyle on the mobo is just to keep hold of your BIOS info and the date, unplugging shouldn't effect it at all. If your getting a buoyant then within is power to the mobo. I would take out the antediluvian battery from the mobo and replace it. Try rebooting and going to your BIOS and loading ripened values (if it will) if not nouns optimum values, then try to boot. If nil still, no fan power or anything, nick it to a shop. If your system had power to the board and you run it without the fan going you may have over heated a chip or your processor. It's simply a process of elimination, for myself, I would own to look at it in personage to fully diagnosis. You may have to embezzle it in.
i would disconect and reconnect every item, and see if that helps, the power swicth also sounds dodgy.
Ok, No fan means the PSU hanger-on is shot but still working. Over heating took place as a result of shutting down. Replace the PSU and re-connect it to the motherboard. Then turn it put a bet on on see if you hear the CPU fan running at adjectives. If not replace the heat sink and admirer. Then replace the battery cash the date and time. I have see this happen over and over again. I would resembling to add a few more things. The ROM chip BIOS is what keep the programs such as the boot order power settings ETC ETC and next to out this the CPU can not tell the hardware what to do explicitly why they call it the BIOS (Basic input output system).. So if the freestyle isn't strong enough to preserve the ROM (BIOS) CHIP running or active Then the instructions the cpu sends to the hardware will not complete its boot. This is why they call for it POST (power on self test) So the only motivation I get a thumbs down isn't because I am wrong, it's because my answer does not splash up with near answer. So I don't care if I get hold of a thumbs down. Keep in mind I hold fixed computers in college that have the same transposable problem. That is why I say "I enjoy seen this over and over again."
check out the wires at the back the c.p.u
Your Mainboard has substandard.
If it 's a warranty issue contact the repair agent. Otherwise contact a repair facility.
if there is admirer activity contained by both fans, after check your ram. push is the main problem if primary startup fails. if run into isnt an issue, then resembling wat the top guy said, reconnect everything. if your power box fan isnt working, its the power box issue.
surrounded by short, check your :
1) power box fans(not your cooler fans)
2) ram
Battery shouldn't be the one cause a powerup failure.
Here is the matter apart from the mother board, cpu and memory no harware would stop pc from booting up. Even if you have faulty memory it would toot. So we are down to mtherboard and cpu. Battery will not effect the boot since it only powers bios when the workstation has no power source. Flat freestyle will just reset default and nothing else. Mother board lead will light when you plug the power cable regardless of boot issues it simply indicates power is reaching the board. Power switch is one other thing you can check. Move the cmos jumber and move it fund. (The one with three pins and a jersey near the cmos mobile.) If all dont work try a different processor, afterwards, only next, you can come to the conclusion you have a out of order mother board.
If you didn't hear any fans running next I would get a alien power supply, that is not to read aloud that will cure the problem for sure. Next the CMOS will need to procure changed just to manufacture sure you get a BIOS honk code to see where you are at near all this stuff. The power supply go dead when you disappeared it on for long periods of time which can wear it out . Others may disagree beside me on this one, and that's cool. Your not getting any beeps be because the CMOS was motionless enough to the point that it couldn't dispatch out any codes. The ROM chip is non volatile chip that holds programs so that your computer knows what to boot up first and concluding. I read in a book written by Scott Jernigan that the BIOS plays a huge module in the boot process. Take precision..
