How do you replace cmos battery on Toshiba 330CDT?

it is inside in the computer, need to dis-assemble it and you will find on motherboard

All you need to do to access the BIOS is to reset it. To reset the BIOS you would need to remove the CMOS battery and place it back, the BIOS password will be back to default and you able to access the BIOS.

NOTE: the CMOS battery is located at the back of your laptop, or it will be much better for you to call a local technician and have him do it for you.

For you to use the recovery disc, once you boot the computer press F12 then select to boot your computer to (CD\DVD drive) make sure that the disc is in the disc tray, then press enter. Your computer will automatically boot into you recovery disc.

To reset the BIOS read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Here’s the worst case scenario. The CMOS battery is hidden under the laptop cover. In order to access and replace the battery you’ll have to disassemble the whole laptop. This is a Toshiba Satellite A305 laptop. The blue circle is the battery.

There are several access panels on bottom of your laptop. These should have markings that designate what is behind each. CMOS battery can be either behind the hard drive panel or the memory card panel.

Alternatley, you can try this link to Tom's Hardware where someone is discussing how to do on a similar model. http://www.tomshardware.com/forum/247842-30-replace-cmos-battery-toshiba-satellite

It is time now to change the battery

There is a battery on the motherboard. Removing it for about 1/2 hour should clear the bios. There are several software methods also. Google 'bios password removal' to find one.

Unfortunately, if you can't remember your bios password you'll have to reset the CMOS. This is usually done via a jumper on your laptops motherboard itself, or removing the battery on the motherboard while the laptop is unplugged and the main battery is taken out. Be very careful when opening up your laptop, make sure all the screws needed are removed, as they are easy to miss. If you don't feel comfortable opening up your laptop, I would recommend taking it to a certified technician.

Hi AshishB, Yes, Toshiba does refer to the CMOS battery in their literature as the real time clock battery. Your retailer is half right, the battery is on the motherboard but its attached via a connector and it can be replaced. Here are links to a couple of venders that sell the RTC battery for your laptop: - Http://www.sparepartswarehouse.com/Toshiba,Satellite,L15-S104,Laptop,Batteries-Backup-RTC.aspx - http://cgi.ebay.com/Toshiba-Laptop-motherboard-battery-cmos-L15-S104_W0QQitemZ170060189842QQihZ007QQcategoryZ3666QQrdZ1QQssPageNameZWD1VQQcmdZViewItem Let us know if you have any other questions and please don?t forget to rate the posting.
