Unfortunately it is a fairly involved procedure, one of the more complex I?ve seen for a newer laptop. If you don?t have prior experience, tools and some nerve I?d suggest you take it to a shop. Some of the more challenging parts you are going to remove are the keyboard, the top half of the case, the wireless card and some of the wiring harness. -Remove the battery pack, any PCMCIA cards, the optical drive and the hard drive. -Open the laptop and carefully pry the keyboard holder (thin piece of plastic at the top of the keyboard. Toshiba has a special tool for this but in times past I have been able to successfully remove other Satellite Pro series keyboards with a plastic probe. Once that is off remove the two retention screws at the top of the keyboard, carefully disconnect the cable and remove the keyboard. -With the keyboard removed you will see the wireless card torx security screw at the top just to the left of center. Remove it, the cover plate and the card underneath. In order to remove the card you will also have to disconnect the white and black coax leads. When removing and reassembling note that these connectors are really small and fragile. -Flip the laptop over and remove all 15 screws. There are three different types so mark down where they go for reassembly later. -At the rear of the computer you will find 2x screws, one to the right of the VGA connector and the other in-between the serial and lpt1 port; remove them as well. -You will have to disconnect several leads and wire harnesses in order to lift off the top half of the case. -Once the case is removed the RTC battery is in the lower right hand corner. -Now all you have to do is reassemble the laptop and test. Good luck and don?t forget to rate this post.

SOURCE: change rtc battery in a toshiba satellite 2415-s205 notebook.

Thanks for the link. At this level of disassembly if you haven't seen the battery, it is not many steps to get to it.

I did notice something green toward the lower left of the base in step 19 that may be it - if not it's just a matter of removing the remaining motherboard screws and connections as it would be on the bottom of the board.

Shame the battery did not need replaced at that time.

Rtc battery is low or cmos checksum is inconsistent

The RTC battery is a rechargeable Li-ion "clock" battery that's buried underneath the keyboard - it keeps date and time going when your computer is turned off. If you're getting this message, you should go follow the screen prompt, hit F1 to enter Setup, and set the date and time, leave the computer on for several hours to charge it (the clock battery recharges only with the computer turned on) and it should go away.

In the rare event that your RTC battery is bad, it's really up to you as to getting it replaced or not - it's a lotta work, and not all the battery vendors out there is competent enough to sell you the right kind of battery (installing a non-rechargeable Lithium battery will kill the thing outright, and there are actually people selling these....). Not having a working RTC battery doesn't really interfere with the workings of the computer - you'll just have to set date and time every time you start it, and you can do so manually or by downloading some freeware such as Atomic Clock Sync to automatically do it for you.

On start up my computer says rtc battery is low or cmos checksum is inconsistent. Press (f1) key to set date/time. I press f1 but nothing happens. blank screen. I can press ctrl alt del and it will restart...

Your RTC battery or CMOS battery is either dead or too low to keep the correct settings, windows will not operate correctly without the proper date and time kept. This battery has to be replaced for your system to operate. Below is the service manual that will advise you of the proper procedure to replace the battery. Once the battery is replaced, reboot the laptop, go to the BIOS screen and reset the date and time, then reboot as normal. In the case of your particular laptop, the laptop has to be disassembled down to the lower case and motherboard. The included service manual has the procedure for this.

CMOS or RTC battery for this laptop : can it be replaced

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://,Satellite,L15-S104,Laptop,Batteries-Backup-RTC.aspx - Let us know if you have any other questions and please don?t forget to rate the posting.
