Re: Failing Laptop Cmos battery and need bigger HD
As a general rule of thumb , the CMOS battery can be found underneath the keyboard. The keyboard can generally be removed by inserting a screwdriver into the thing gap at each side at the top and then gently lifting the meyboard up. Be careful with the cables connecting the keyboard to the motherboard though!
I cannot find a removal guide for the hard drive. However , look for a slot or cover on the side of the laptop , similar in size to your cd drive. Then turn the laptop up side down and unscrew one of the screws thats somewhere near the slot or cover , remove the cover and slide the drive out, If you can get the cover off but not get the drive to slide out , try unscrewing another screw as most laptops have a few screws holding the cover on and another to release the drive.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

try this shut down computer unplug the power supply open the tower remove the cmos battery if you don't know how the battery looks just look for a one similar to a cel battery like the ones that are use for watches only bigger. Then plug your compu back on turned on never mind the message you get after that again turned off unplug the power supply again put back the battery make sure the letters and numbers are facing you plugged back turned on if work you will need to reset your date and time again.
Hmm Well I cant seem to find your computer model anywhere on the Internet.... but assuming its a basic compaq Computer All you would need to do is buy the correct type of Hard Drive (Ide, sata) open the computer up with the power unplugged and static protection..... now some computers have multiple Hard Drive bays and some only have one so you will need to install your new HD into a bay assuming your replacing your current HD you would remove the old HD and install this one in its spot dont forget to Check the jumper setting on the Hard drive to either match the drive your replacing or as a Master in a single HD setup also plug in a power source and the data cable into your new drive or it wont work.... it should be that easy almost all new computers will automatically configure it in the cmos for you.... if its a replacement for your main HD then it will need You to install an Operating System on it before you can use it.
To reset the CMOS the easiest way is, remove the motherboard
battery for ten minute then install it again. It will clear the CMOS. Then reset
the CMOS/BIOS setup, date/ time etc. Another way to clear CMOS is, reset the CMOS
Jumper in motherboard.
To detect your hard drive you can try to check by change the
hard drive cables. Change the port in motherboard. Check the BIOS setup and
reset it if need.
appears that your hard-Drive has developed A Fault.
if you feel competant, to attempt this then do so.
start the computer, and enter The Bios settup. usually F2/esc Or del at startup. Once in the Bios, scroll across the pages or locate Boot device list. what you need to do, is change the device priority, so that the computer searches the CD/DVD Rom drive first, with your CD Inserted.
after you,ve changed the boot priority, save and exit to cmos.
Option 2. remove the side panel ( And mains Power lead )
locate The CMOS battery, round silver Battery, from the Motherboard for 10 seconds, replace the battery, side panel, power lead. And restart The Computer.
Hi, and welcome to FixYa The computer may display a prompt to press F1/F2 or any other key to enter setup each time the computer boots as a reminder on how to enter CMOS. However, if the computer asks to press F1/F2 (or another key) to enter setup and does not continue, this issue can be caused by any of the below possibilities. 1.New hardware has been recently installed. 2.Error or confliction with settings in CMOS. 3.CMOS battery is bad or failing. Solution: New hardware has been recently installed If new hardware has been recently installed into the computer, it is likely that you are receiving the prompt "Press F1 or F2 to enter setup" because CMOS needs to verify that the new detected hardware is properly being setup in CMOS. Error or confliction with settings in CMOS If no new hardware has been added to the computer or the new hardware has been removed and you continue to receive the error, it is likely that there is an error or confliction with the CMOS. Press the key requested to enter setup and verify that all settings are correct. If everything appears to be correct try resetting the CMOS values to the defaults and/or Reset Configuration Data. Additional information about how to do this can be found on document CH000976. If all settings appear to be correct, save changes and exit CMOS setup. If the error continues to appear, enter setup again and restore all CMOS values to default. ·See our CMOS page for additional help and information with the CMOS. ·Additional information about getting into the CMOS / BIOS setup can be found on document CH000192. CMOS battery is bad or failing If you continue to receive the prompt to enter setup each time the computer boots up and you have attempted to follow the above suggestions, it is also possible that the CMOS battery may be bad or failing. Generally; when this occurs, the computer is not holding the time or date correctly. If this is occurring it is recommended that the CMOS battery be replaced. regards /Teis the Wiz - -> Vote "FixYa" :-)
1. Check the BIOS, make sure the hard drive is being recognized and that
boot order includes the hard drive, preferably before the LAN/PXE boot
item. You may also want to test the memory in the laptop: http://www.memtest.org/
2. (ONLY if your tech savy), I'd check all the connection between the hard drive and the motherboard,
usually there's some kind of adapter or ribbon that connects between
the two but not always. You may want to look for a CMOS reset or pull
the CMOS battery.
the computer is not recognizing the contents of your hard drive. you'll need a floppy with command.com, iosys.com and sysinfo.com on it. when inserted into the drive cmos looks here first. if you can access the cmos, check the search parameters to see what the computer boot up sequence is. you may want to change it to recognize the cdrom first, then the hard drive, then the A drive. I had a compaq armada that gave me the same message but I was able to reformat the drive off DOS 6.2 and changed the boot up sequence.
try to get to the jumper next to the cmos battery in the mainboard. by changing its position for some seconds while power is off and putting it back , cmos is cleard. start the board hit delete to enter setup and exit saving chages.
