Question about Compaq Evo D500 PC Desktop

Reset BIOS password

I have a compaq evo d320, the previous owner had set a password on the BIOS/utility set up, I can login into it by just pushing enter 3 times on at password stage then utility loads, but I can't change anything in it, as if I'm locked out of changing any thing.

I tried a method of removing battery, it did kinda look like it had reset but then password page came up again upon entering utilties, plus it also said that the CMOS was invalid.

What else can I do to resolve this issue and thanks in advance.

    I can't see a small bit of coloured plastic near the battery, I can't seem to see no switch I could switch at all. I tried the battery trick again but to no avail. Hmmm...if I could find this jumper switch then maybe I could get somewhere.

    Hey leecom72

    Yeah I have found the jumpers, tried moving it over for 10 seconds then moved it back, I restarted my computer, then I see the ram load then it loads all this stuff then restarts, it does that 3 times before loading windows again, when I try to intefer and press F10 to go into bios, it lets me in, but still cant change anything, and when it does load the windows everything is blank except for the wall paper, there is have nothing else showing. So i did jumper again, let it restart 3 times and load windows then all my stuff for windows is all back.

    Don't know what else I can do.

Ok, this time try to reset the bios using the jumper (small bit of coloured plastic near the battery) move the position of the jumper and hit the on/off button, the computer should not start if you have done this right, move the jumper back to its position and start the pc, go straight back into the bios and set the date and time, hit F10 and ok or yes and you should have full control of the bios.
if there is no jumper, remove the battery again for 10 mins and make sure the power cord is removed from the back, hit the on/off button a few times to drain any residual power, after 10 mins replace the battery and do what i told you to with the bios

good luck

    if there are two metal prongs near the battery housing then thats the cmos reset, you can short this by usind a flat head screwdriver to bridge them and press power on, if there are no prongs, remove all power from the PC and remove the battery again for 10 mins, put it back after that time, when the computer restarts it will say "cmos invalid, press F1 to continue or Esc or Del to enter settings", you need to go into the settings to set the time and date, all passwords should be cleared

    good luck and kind regards

    Does the bios still ask you for a password to chane the settings?

  • Lee Hodgson
    Lee Hodgson Nov 18, 2008

    ok give a little time on this, the cmos should have reset when you took the battery out and cleared the cmos with the jumper, power had been removed from back! and left for 10 mins minus the battery, i will check to see if the bios chip has onboard memory and see what i can do about this.

    is the pc a EVO D500? just to verify because i think i may have a soloution for you :)

    Since HP provides no useful documentation for the
    D320 I do not know if the CMOS reset is a button or jumper. I will
    assume that it is a button.

    There should be a a small white button in a yellow
    circle next to the IDE connectors. Please press and hold this for 15
    seconds. This will help you reset cmos but this is a manual operation.
    Disconnect the power cord (again) then press the Clear CMOS
    button for 10 seconds. If it is a jumper move the jumper from the two
    pins it is on to the other position for 10 seconds and then put the
    jumper back on the original pins like i explained before.

    Keep me informed please

    Hope this helps.

How to remove a bios password from hp 6720s

Why can't people put a problem in the right catagory?
Generally, you can remove the Bios backup battery or use the jumper on the motherboard to reset the bios completely.
Google "reset bios" to get an idea of how to do it, or do the same in Youtube for a video. Lots of them are out there.

How do I get the battery out of my acer laptop

Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572
. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Hide file folder WITH A password

For the most part you need 3rd party software, or a USB drive with security built in. Just remember you are at the mercy of those companies if you lose the password. Plus some software will only works locally. For instance if someone removes the drive and connects it to another computer the files are wide open.
Win 7 Ult and Ent (high end editions have Bitlocker built in.
A simple way is to create a folder within his login account docs and choose hidden as the properties. The only way to see it would be to change folder properties and make hidden files visible. This is just cloaking, because anybody with admin rights can see them.

How do i reset my computer to an earlier date?

Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
