You need a replacement battery for the CMOS system on your computer.
The CMOS system contains the BIOS settings configuration and also runs the real time clock. If the real time clock does not stay in sync, this can have a negative affect on your installed operating system ( for example, a windows computer will not allow ANY system updates if the difference between your system time date, and the update servers current time and date is offset for 24 hrs. or more)
Yes.........the Time Continuum has stopped.........we have surpassed the Speed of Light........ Replace the CMOS Battery. Also known as the RTC Battery. Real Time Clock Battery What is the HP laptop's Product Number? This is P/N in the white Service Tag, on the Bottom of the laptop. Post back in a Comment. Regards, joecoolvette
The laptop has to be completely disassembled down to the motherboard (System Board) in your hand. On the bottom of the motherboard is the RTC Battery.
Since the laptop is brand new this falls on the place where you purchased it, or Dell. It is still under warranty as far as replacing the RTC Battery. (It came with a bad battery. They need to replace it, not you)
I suggest to try removing the battery and get it back and start again ..If it crashed and turned off it may need to be disconnected from all power before starting again ..Or the battery may be in short and conflict with the ac power..so ..try to boot up with the ac power alone .. The blue light is not usually a fault ....when the board is damaged the light is usually amber..
If the date and clock is not keeping your settings to blame is the bios battery ..and need to be changed..The battery is usually on he main board just under the keyboard..and the wireless card ..and can be accessed from the front if you remove the hinges cover..than all the screws of the keyboard ..slide the keyboard toward the display for an inch and lift it ..Unplug it from the ribbon ..and you will have the wireless card exposed..You have to remove this card also and you will see the battery .. it is possible to not be able to remove it ..and have to open it in half to get to the motherboard ...to do that you have to remove all from it ..including disk drive ..battery and hard disk ...and all teh screws for to open it in half .. or ..for most compaq model the battery is accessible from the back .. take a look on these videos .. http://www.youtube.com/watch?v=R57XXxxLgoE http://www.youtube.com/watch?v=aZfbH6-slXE http://www.youtube.com/watch?v=aboaX0fI83o here are 3 different situations ..try to see if your model have access from the back to the battery ..if not ..you have to strip the front and see if there is access under the keyboard..
Hi, try this:
- unplug from mains - remove laptop battery - remove real-time clock (CMOS) battery. - wait 5 minutes - replace the RTC battery and then plug in - without the laptop battery. The laptop battery cannot be present when you remove the RTC battery and shouldn't be there when you power on.
