Bad RTC Chip, I read your solution, where is the battery? I can not seem to re-boot the unit.

The terminal has a depleted internal battery that must be replaced.
its is fixable.

I am not familiar with that CC reader, but RTC mean "Real Time Clock" have you tried just to set the date/time?

In your computer (as well as other gadgets), the battery powers a chip called the Real Time Clock (RTC)chip. The RTC is essentially a quartz watch that runs all the time, whether or not the computer has power. The battery powers this clock. When the computer boots up, part of the process is to query the RTC to get the correct time and date. A little quartz clock like this might run for five to seven years off of a small battery. Then it is time to replace the battery.

This does not explain why your computer would not boot, however. You would expect the computer to boot fine but have an incorrect time and date. The reason your computer would not boot is because the RTC chip also contains 64 (or more) bytes of random access memory (RAM). The clock uses 10 bytes of this space, leaving 54 bytes for other purposes. The BIOS stores all sorts of information in the CMOS RAM area, like the number of floppy and hard disk drives, the hard disk drive type, etc. If the CMOS RAM loses power, the computer may not know anything about the hard disk configuration of your machine, and therefore it cannot boot.

Many more modern computers are not quite so dependent on the CMOS RAM. They store the settings innon-volatile RAM that works without any power at all. If the battery goes dead, the clock fails but the computer can still boot using the information in the non-volatile RAM area. I would change the battery and make sure unit is unplugged and my other hand is touching the metal frame on the computer to stop static discharge. Blow out the inside of the computer completely.Start computer with case off and make sure all the fans run and don't sound like a siren.Replace anything not running.It may not boot if the BIOS can't see the hard drives. You might have to start computer and watch the screen and when it asks you to hit a key to get into like the bios do it and see if you can reset it. If nothing seems be running right maybe the power supply went out they are real cheep at Tiger Direct.

First of all BAD RTC can be fixed. Problem will come up if your internal battery is going bad and most of the time it comes with the "TAMPER" message also. By replacing the internal battery and reloading the Verifone program will solve the problem.
Just to let you know the Verifone machines are equipped with multiple sensors inside it. If for some reason the sensors were disturbed (i.e. broken plastic casing, unit dropped,...) , the machine will come up with the BAD RTC and TAMPER message too. Hope this answers your question and if you still need help you can us at (775)358-2922 ask for Randy. Thanks

bad RTC can be repaired. the machine is equipped with multiple sensors inside. if one of them goes bad, or the Battery is dead tampering or bad RTC will show this can be fix by replacing the sensor and or the battery if you need this to be done call me @ (775) 358-2922 hope this help : - )

Bad RTC suggests a bad Real-Time-Clock, and it's usually bad because the battery for that clock has been let run down, or humidity killed that battery. Try replacing the battery first, then consider replacing the chip (using a soldering iron and replacement chip.)

The "RTC chip" is an integrated circuit that provides the R(eal) T(ime) C(lock) functionality. If your device cannot keep the correct date & time, it's time to replace it.

To reboot, turn the device off, and then remove the battery.
Wait 60 seconds, reinsert the battery, and turn the device on.
