Take the battery out. Short the terminals or just leave it out for a few hours. Put it back in and no memory of a password left.

How to reset bios password emachines d735 series?


I think you mean D725, not D735. I don't think that there is an eMachine D735 model.



The D725 series is a laptop.

Unfortunately, there is no easy solution.

You will need to open the laptop, if you know how to do the reset.



First disconnect your machine from power; this is an important step (otherwise the next step won't work); then open the laptop.

Be very careful not to cause damage with static electricity from your body.



After you open it, remove the CMOS battery for 20 to 30 minutes.

That will make the motherboard forget all the CMOS settings.

Reinstall the battery and try to boot-up.



There used to be a software utility toolkit to reset the BIOS password, but it has now disappeared from the Internet because it could easily be used for illegal purposes.

I hope this helps a little bit.

I want to format my lenovo 3000 n100 laptop,but in boot screen it is asking for password and I forgot my password. My laptop is also not startin.Please help.


If you are able to open your laptop, take out the little battery for an hour or longer. This clears your bios, perhaps there is a jumper nearby to speed this up. All bios passwords are gone then.
Next you open your bios and make your cd/dvd the first bootdevice.
Insert your windows and follow instructions. When asked where to install windows you delete all drives and then create a new drive to format and install windows on.

When i turn on my lenovo 5000 y500 laptop very slow booting takes place


There are so many reasons can cause a Lenovo computer running slow at boot up, it is hard to identify just what might be dragging down your Lenovo's performance, let alone implement the necessary technical adjustments to fix it.

So if you want to address the issues more easily, I'll recommend you try a Lenovo speed up software, available here: http://www.speeduplenovo.com/

I have a Lenovo A3 series all in one desktop computer and it is not recognizing my password and I am locked out. I put myself on as administrator and the computer was turned off before I backed up the...



first make sure the caps lock if off/on whatever applies the password when you typed it in

Remove a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings

as well as the password and you'll need to re-enter all settings.

Under the keyboard or bottom of laptop - If you are working on a laptop computerthe location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

If it fails, then try to remove the battery for at least one hour.

click start control panel Open User Accounts in Control Panel. On the Users tab, click the name of the user whose password you want to change, and then click Reset Password. In New password and Confirm new password, type the new password, and then click OK. Notes You can change passwords only for local computer accounts, such as guest, administrator, or accounts you create for your computer. You cannot change your network logon password in User Accounts. To change your own password, press CTRL ALT DELETE and then click Change Password

hope this helps

Hi can anyone help me in reviving my lenovo y500 laptop to read cds and DVDs


Sounds like your CD/DVD drive may have quit. Taking your laptop apart to replace it can be a challenge. I would try an external USB drive.

My camera is not working


since you have formatted your laptop you have erased all the drivers especially the camera driver for your laptop you will need to get a new driver for the camera but if you laptop came with a disc you will need to check if the drivers are available in the disc.

No audio


Hello Jatin09,

Let's start by removing all of the other audio drivers. After, reboot your laptop and install only the audio driver from the cd. After doing so, if the problem continues, then you may want to try repairing your windows system files - given that you have the installation cd that came with your laptop.

Hope this answers your question and that it helps.

Thank you
