Question about Dell Optiplex GX280 (99301) Motherboard

6 Answers

Resetting admin password on setup.

One of our 280s we got in is setup-locked by admin password. We don't know password, nor can we get ahold to supplier to see why it was locked. Dell Optiplex GX280 tower. BIOS version A03. Will reloading/updating BIOS reset the password? I can put in another HDD with windows loaded and try that. Resetting CMOS didn't fix it. Thanks.

    The admin password locked the BIOS, and the settings are as follows:

    Boot priority is: 1) HDD 2) N/A 3) N/A

    the SATA 0 is on, SATA 1 is off, both PATAs are off....seems someone did this for meanness, they turned off the floppy, network, optical, everything except HDD, and they wiped the HDD.



    I did the battery/power switch deal and no-go, I will try the jumper part next. How do I do the jumpers? just pull and put back in? or do i hold power button while doing that?

    -Mike.

In the model 280 Optiplex, remove the jumper, they have two pins only, turn on the computer, wait for 1 minute. The jumper is located close to the power plug, in the right side, you read PWD, theres is it, i did it and working fine...

First, all the info you need is available from Dell at their website. I had the same problem and simply looked up the docs on the dell site. They have diagrams of the mommy board and instructions for about all you need. In this case, password reset: you remove the jumper (power down first) and then power up.

The jumper's location varies depending on the type of case: the gx280 mini-tower that I have has the jumper in the corner next to a rectangular connector; the wiring or which obscures the jumper, but it is there and disconnecting it (and power up) will fix the problem: it did for me.

Remove the CMOS battery and hold down the power button for thirty seconds. This will reset the CMOS/BIOS. If it doesn't the is a jumper on the motherboard that will do the same thing. Replace the battery and start the machine after that

    The admin password is in the Operating System?

  • David
    David Jan 19, 2009

    The jumper is next to the CMOS battery on most boards. The Jumper is three pins with a 'plug' that covers two of them. Move the 'plug' to the pin that is not covered and the center pin. Do this with the computer unplugged. Leave it there for one minute then put it back on the original two pins. Then plug it back in and the BOIS should be reset.



    If you are not sure which jumper is the CMOS jumper, give me the model number of the motherboard and I will look of the schematics.

Why is it asking for password


Hello, When the computer was first setup in the bios, someone set it to be password protected. When you bootup the pc, hit f2 to go into bios and reset the admin password or if it is the password on the login screen you will have too get password cracker or take to a tech too have password removed.

How to switch to admin login on my sons laptop


Sometimes the existing user is the Admin. This question arises every day, and here is my post. Good Luck


Lost Windows password:



  • Login as Administrator. Try with no password (load safe mode if you don't see Administrator). Press F8 during boot to access Safe Mode.
  • Login as other user (if other user is availible) and manage users. Must be an administrator.
  • Reformat computer.
  • Use 3rd party software to remove password. Like http://www.top-password.com/reset-windows-password.html

you could try Compaq as the bios password some manufacturers place this password on there computers for maintanance reasons
or you might
On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard. If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (integrated circuit) on your motherboard. Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it. RTC's which require external batteries hope this helps

I am trying to secure my D-link router, I do not know how to lock it so that I do not get unauthorised access.


As you have not mentioned the make/ model of your router, I would describe the router security settings in general.
First you have to access the router through web browser (Internet Explorer) by typing the IP address of your router in the address bar, which is 192.168.0.1 OR 192.168.1.1 (Default router settings are written under the router)
(unless you've configured otherwise, the default username is admin and the password "leave it blank" OR Type "admin") and lookup for the options to do the following: -

1.On the left-hand side, under Setup, click "Wireless Setup" 2.Under "Wireless Security Mode", select your desired encryption method (preferably WPA2-PSK)
3.Choose/change the Network Key - it can be anything, as long as it's 8-63 characters in length
4. Click Save Settings.
Now your router and your connection would become secure and the user has to provide the network key to access the internet.

Also, for additional security, you may try the followng steps: -
1. Change the SSID (Name) of the router
2. Change the default administrative user name and password
(The above step would prevent unauthorized access to your router)

In the screen shot below I have highlighted the above mentioned options for DLink Dir300 Router, which would help you.

Now your router and your connection would become secure and the user has to provide the network key to access the internet.

Let me know if any further clarification/ assistance is required.
Hope it helps! Good Luck!

Hi I try every solutions existing on the internet but I can't connect to 192.168.0.1 ip to configure my di-704 thanks


Here is a Webconfig for your router/gateway http://support.dlink.com/emulators/di704/IndexLogon.htm

Also the default login is admin with no password but sometimes may use the word password for the password with the login of admin

Ci have a d-link router, and cannot remember the password! i don't have the setup cd and i'm afraid to press the reset button at the back. how will it recognize my laptop and begin the setup?


the reset button restores default settings of the router. the address is 192.168.0.1 . that will get you to the router setup so you can input the security settings ssid and passwords. the default username to get into the router is admin and password field is blank.

Access BIOS


Oh, you can see it in the splash screen. The screen where the 'Compaq' logo shows up has the keys to what goes where. See the bottom of the screen.

See 'Setup' etc. If it doesn't show up (doesn't in mine, as my monitor starts late), then start it up and then reboot. The monitor doesn't switch off here. So, you can see it.
