BIOS time and date is resetting if I don't have the laptop battery in and if I don't have the laptop plugged in. In order to stop that I'll trying to change the motherboard battery. However I do not see it when I take the bottom cover off. I'll trying to find its location.
Manufacturer: Toshiba
Model: C55-B5299

This laptop model does not have a CMOS battery. On the motherboard you will see a spot that one should be located. If you disconnect or let your main battery run dead you will have to re-enter your date and time settings when booting your laptop for the first time.

@itsd_btech What is the solution to this problem then? My battery doesn't charge and my laptop only runs while plugged in, and needs bios time update each time I plug into a new socket.
I would recommend replacing the battery with an OEM quality battery. Either your battery is not recognized by the laptop or is failing and needs replaced.
buy a good replacement battery (about $20 USD, put in new battery and charge fully in the off position. Re-enter current date n time in BIOS and all should be well
Be sure to train the new battery! When they first charge they may only last 30 min to 1 hr. But after draining to about 10% or so and fully charging to 100% you will get way longer life. I train new batteries three times for best results, although the most benefit occurs after the first full cycle.
i replaced the main battery, it has no rtc battery, pressed the on button, the on button stays lit for 5 seconds then turns off, the dammned thing wont turn on !!!

Hi Alx,
I would guess that it may be under this cover.

It was one of my favorite childhood pastimes :)
This model does not have a CMOS battery on the motherboard. The spot you are showing in the picture looks like a potential placement. If you take the motherboard out you will see underneath there is no battery.
I'm having the same issue. I let my battery die by watching a movie that I fell asleep to. Now all I get is the Toshiba splash screen. No bios, nothing. There is no battery. I looked.
Does anyone know a fix for this?

This model do not have any CMOS battery, …ignore the shape of battery on the mobo, there is no battery on the underside. First time I ever encountered this in my 17 years dealing with computers. It's very unusual but it's true

I have a Toshiba Satellite L55-B5267. I am also unable to locate a battery on the board. I am getting prompted for a BIOS password. How do I clear the password. No battery so I am unable to locate the correct jumper location on the board.
Mine did this I replaced the hard drive and reinstalled windows and boom fixed

I had the same problem. Just replace the battery, fully charge the new battery, set your date n time and you are all good to go.
