Toshiba Satellite B550 is there a CMOS battery on it?

Boy, I tell ya, I had no luck whatsoever finding any information about your laptop, so I can't help with any clues about where the CMOS battery may be located. There were a few threads that talked about how some models of Toshiba Satellites don't have CMOS batteries and instead rely on power from the main battery, which means you end up having to reset the CMOS memory every time you remove the battery. However, none of that was specific to your laptop, so it may not apply.

On the other hand, I did find one seller on Amazon selling batteries that are supposed to work in your laptop. Here's a picture of what it's supposed to look like.

And a link to the Amazon page so you can take a look for yourself.

Replacement CMOS Battery For Toshiba B450 B451 B452 B550 B551 B552 L35 L36 L40 L41 L42 L45 L46 L47 BACKUP Reserve Button Cell Batteries 3 Pins 2 Wires: Amazon.co.uk: Computers & Accessories

I'd start by removing the bottom cover; hopefully they didn't make it ridiculously difficult to replace the battery by doing something stupid like putting it under the motherboard. Look for that little white connector on the end of the wire in the picture; I'd start looking in the corners by the hinges. If you find it, follow the wires to the battery pack; it may be under a cover, glued to the case or just taped down.

That's about all I can come up with for you; maybe someone else will have better luck finding any kind of repair or teardown guides or videos for you. Good luck and let us know what you find; it may help someone else in the future.

P.S. If you do figure out how to replace the CMOS battery, you might want to consider taking pictures and creating a guide for the poor saps who have that same laptop and no instructions either. It's really not hard to do and there's always people here who'll help you through it if you run into problems.

Yep, their infamous utter stupidity is here; buried, but replaceable: https://www.aliexpress.us/item/325680415...

There's a similarly shaped board with the middle finger battery (soldered). Welcome to the world of Toshiba hostile repair design. When my mom's L755 died, I took it to the trash gracefully. If it wasn't in my teens when I didn't need to retain parts like LVDS 768p screens I would have had some fun with it, intact.

I was holding the power jack in with hot glue because the plastics on that freaking thing broke, as well as a few standoffs (noncritical, so I removed the screw and standoff). The issue with Toshiba was they took hostile design principles into the laptop business. — Nick

Toshiba laptops are 4 shots in the chamber if you play Russian Roulette with 4 bullets varied in the chamber waiting to get you. Here are the 4 variants:

Cheap (read: awful) Tosibas, commonly the A series: Soldered to the motherboard; I had 1 in my teens, and 2 with this design from junk lots. Not easily fixed for most DIYers which was the scam Toshiba banked on. These are the sole reason I will not touch a used Toshiba, even a good one. I will send them to a recycler without an ATTEMPT because of how commonplace this was up until 2011, especially models like the A series which I ran into it before. These are often scrapped due to their age!
Socketed bare cell (socket soldered to board, not battery): Not hard, but can be buried. Fesiable for DIY repair. Some like the L755 allow access under the RAM door, while others need bottom cover removal. SOME REQUIRE A FULL DISASSEMBLY DOWN TO THE MOTHERBOARD.
Lead battery: Again, DIY friendly but often buried so takes a bit to open and replace.
Capacitor bank (relies on the primary battery which runs the laptop to retain CMOS RAM): Evil. Once the battery stops holding a charge, the CMOS RAM stops as well, and it's made worse by Toshiba refusing to sell parts and NLA'ing a lot of the batteries after 5-6 years. 3rd parties will often step up to fill the hole, but this shouldn't be needed.

Simply put, Toshiba is awful; there is zero consistency, which is a chronic problem nobody else is known for. Open it and see, but if it's a budget model I'm almost confident it's that unrepairable soldered type. Even an RSA-signed BIOS HP is more bearable than a used Toshiba where it's a shot in the dark.
