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.

I have a toshiba g25 av513 when it the power button is pressed a message shows up on the screen stating RTC battery is low or CMOS checksum is inconsistent. the laptop is plugged in


Hi. This is likely due to a small watch battery inside the machine (called the CMOS battery) being dead. Replacing it usually requires the tools and skill of a qualified technician.

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.
