It seems, from the error that you are getting, that the CMOS Battery need to replace. The battery is week or down. Due to this the time is not getting saved in the CMOS. Pls change the battery. Need any more help. If solved pls let me know.- Cheers Parveen

If the motherboard is not booting then what is the solution for it?


To detect motherboard problem you need first test your memory, remove any drives and try to boot to BIOS, if nothing on LCD then try to boot with external monitor, if there is no any video signal output then look to led indicators, if there no light then you need to test power adapter, power socet on motherboard and fuse on moserboard near power socet, if power OK then try to reball south bridge or replace it, also you need to do it with 100% working CPU and memory!

Whenyou plug in the power cord is there any lights whatsoever on the laptop, wherethe plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the computer is trying to boot or may have booted,but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe you have a Static ChargeBuildup. Remove the Power Cord, then Press and Hold the power button for30 seconds. After 30 seconds plug the power cord back in and hit thepower button to see if it boots. Maybeyour memory is bad or the memory slot is bad.Removethe Power Cord, Open the Case and remove one of the memory chips. Set thechip aside then try rebooting the computer. If it boots, then you knowthe memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and tryrebooting. If it fails take the chip out and set it aside, then put theother chip in and try booting it in both slots. If it boots, just toverify that the chip set aside is bad, mark an x on it and put it into the openmemory chip slot and try booting.

Laptop wont boot and can not get to boot menu or bios setup


Try this: Pull the battery and power cord. Now hold the power button in for about 30 seconds. Plug the power cord back in (DO NOT put the battery in yet). Now try to power up the computer, if it boots fully, shut it down and put the battery back in. Then boot it up again. This will sometimes work. If it fails to boot with the battery in (yes I have seen this too) replace the battery.
If it fails to boot with just the power cord and you are getting no beeps, trying pulling the memory. Most laptops will have two slots for memory and a chip in each slot. Turn off the laptop, remove both chips, then place one back in. Try to boot, then power down again and try just the other chip. If it fails to boot on one chip, that would be the bad memory. If it fails on both, try the same steps with the other slot. If it works on the other slot, you have a bad memory slot.
If non of the above work, you may need to take the laptop apart to get to the bois battery. Removing this battery, with no power to the computer (plug or big battery) will reset the bios and may clear your issue.
Go with the easy steps fist, and I hope they work.

I have an hp m8425f and the tower won't turn on,


Remove the Power Cord, then press and hold the power button for 30 seconds. After 30 seconds, plug the cord back in and press the power button. If it works, you had a Static Charge Buildup that had to be released.

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.If the above two steps fail, pull the main power plug that comes out of the power supply and plugs into the motherboard. The end that plugs into the motherboard is probably about two inches long, Grab the release latch on it and press it while pulling up to unplug it. Wait 30 seconds then plug it back into the motherboard. Push it back in firmly.
Try turning on the system.

My toshiba mini laptop NB305 will turn on but it wont boot up, and the screen stay black, how do I fix it?


pull the battery, disconnect the ac adapter and hold down the power button for about 10 seconds, then put the battery back in, plug it in and try booting it. If that works, you're good, if not then the motherboard most likely needs to be replaced.

Compaq Presario CQ50-139WM will not boot.


first thing i would try is to unplug the powercord from the surge proetctor and from the computer. turn the computer over and take out the battery.

with the battery out, press on the power button for 30 seconds.

now put the battery back in and plug in the computer and try booting it.

sometimes static electricity builds up inside the computer and this will dissipate it.

Getting power but wont boot up or anything


pull out everything in the computer except what's required to boot...so any pci cards or video cards (if you have onboard video). you can also try pulling out the ram (while unpowered AND unplugged) and then booting to hear beeps...if you pull the ram out and the computer doesnt make a sound, its probably a bad motherboard and needs to be replaced. if you hear beeps, try replacing the ram or disconnecting other parts...like harddrives, optical drives, modems and what not.
