Question about HP Compaq Evo Notebook N620c

1 Answer

Replaced the CMOS battery now I have a system date confict in win

I replaced the cmos battery on my Compaq Evo n620c and the date and time reset to 1980. I changed the date and time in windows. now when I started to download updates, I get a error saying there are differences between my system time and windows time.

I restarted the computer, press F10 entered bios setup and there is no place to correct the date and time.

Is there a command line code to run? and if so how do I do it.

thanks in advance

Try changing it at DOS:
Clic Start--->Run
Type CMD and press enter.
type TIME, it will tell you the current time and will ask you to enter a new one, if press enter without typing any value then no change is made.
Restart and try de updates again.
Good Luck!!!

Where is the coms battery for compaq evo n610c located


hi,


If your in the need to replace your cmos backup battery on your Compaq Evo N610c, N610v, N620c Series Notebook help might be just around the corner and thru the usage of this guide familiarize you with what you will need to solve the error prompts flashing on the screen regarding corrupt cmos. At this point you have come to realize that the notebook is no longer booting your Operating System should that be Microsoft or Linux OS's.
The first thing you will need to be familiar with, is where the cmos backup battery is located on your notebook. You can start by turning over the notebook to the bottom side and adjacent to the Main Battery will be a small rectangular compartment held down by two screws (Mini PCI Compartment Cover).

db96_2.jpg These two Phillips head screws must be removed in order to expose the cmos battery that's held in place by a battery holder.

db99_2.jpgThe battery holder accomidates the BR1225 Lithium 3 volt battery, allowing the two potentials of the battery to maintain power to the cmos chip and therefore sustaining the clock/date settings as well as the boot sequence set by the end user. These non rechargeable lithium batteries provide operational function while the notebook is powered off.
After having identified the location of the cmos battery, and having removed the two screws that hold the black rectangular plastic cover, use a non magnetic/plastic tweezer or equivalent probe and pry out the BR1225 battery retained in the Battery Holder. If you don't have access to a Volt meter to determine the diagnosis of the battery, then assume that it requires replacement, where a replacement would be any brand of battery that suits the BR1225 specs: 3 volts approx 40maH 12mm diameter 2.5mm thickness no wires and no connector. HP refers to call the cmos battery by the name of RTC Disk Cell. To order from HP refer to HP Spare Parts Number 241439-001 (Miscellaneous Plastics Kit Component) Applicable to Compaq Evo Motherboards: 291581-001 (Evo N610c) and 319778-001 (Evo N620c)

d0e4_2.jpgNow, while replacements can be for just any electronic store near your home/business, pharmacies also carry these types of batteries, but if your choice is to buy them here on ebay, we recommend buying them from a seller who has other Evo Part integration and has proven themselves to be fully knowledgeable on HP/Compaq Evo Models, whereby most likely they will stock other parts you will need for your Evo such as Hard drives, LCD inverters, LCD display, optical drives, memory and maintenance care products. Below are two sellers and the ebay store links to their Cmos Disk Cells. We have no affliation with them, but as buyers we have purchased from both of them in the past with good success and can recommend them.



good luck

I have compaq evo n1000c laptop. recently I have changed the cmos battery and now its not booting. do I need to update the bios.? how can I resolve the issue?


If you just replaced the CMOS battery, when you took the battery out it lost all of its BIOS settings. You will need to go back into the BIOS and set the time and date as well as all of the other settings that you require. If you do not know all of the settings you can find the option to set it to the default settings. This will usually work to boot the computer.

Be sure to email me back if you have any more questions orif you need any assistance with this solution. Thank you

Compaq evo n610c doesn't hold date and time.


Your CMOS battery is going out. Replace it before you lose the rest of your cmos settings.

Give me password for compaq evo n600c


You can remove your bios password by reseting your CMOS battery or jamper. You need to open your notebook remove first the battery and all screw at the back of your notebook. You can see there a CMOS battery together with the CMOS jamper. Just read it you can read CLRSCR which means clear cmos, just pull it with in 10 seconds and insert it back. Now you are done to reset bios.
