I want to replace cmos battery in my toshiba satellite P205-S8811
Toshiba laptops are a wildcard. They have used “buried” primary batteries (must fully disassemble the notebook), some are easy like my mom’s Toshiba L755 (cheap junk, I don’t miss it) where it was under the RAM door. Others (Read: low-cost new, often “disposable”; these were absolutely designed to be evil to maintain on purpose) use a soldered CMOS battery. These soldered batteries are a absolute PITA to replace for non-techies (then again, we RUN from these). This variation is why the expert response is this: Avoid all Toshibas that are new enough to have this garbage (how I do it)The exception is truly vintage ones in nice condition - think anything up to Pentium II and MAYBE PIII. PIV and up are “modern”.Look up the motherboard and base it on that (not always possible to see both sides, but if it’s not visible on the bottom it’s often soldered)Negotiation if it is (I don’t bother) This one has a soldered CMOS battery :(. Not an easy DIY job! If you want to do this, you need a tabbed battery (or a spot welder), and you need to make sure it isn’t rechargeable. On some of these, the cell is “rechargeable” rather than being a “primary” battery like the socketed ones. If the motherboard expects a rechargeable one and it’s replaced with a non-rechargeable primary, it will explode. It’s nonsense like this why Toshiba is not missed since they left the market.
