Question about Toshiba Satellite M45-S169 Notebook

1 Answer

My Toshiba Satellite M45-169 keeps freezing

Can anyone tell me what these messages that I receive on startup mean:

"System CMOS Checksum bad-Default configuation used"

"System BIOS Shadowed"

"Video BIOS Shadowed"

My computer was working fine; then one day...Bamm; it keeps freezing up on me....I can't always boot up when I want to. When I do boot up and it's working, everything is fine, then I click on something and she freezes up. I used my original disc to put a whole new XP operation system on it....I cleaned off the heat sink.....I've run the Toshiba diagnostics program and everything passes....then Bamm, she freezes up.

Any ideas would be much appreciated.

1. The battery on the motherboard has died. Replace battery.
2. The BIOS is corrupt, reflash BIOS.

Most likely #1, very rarely #2. Pop out the battery on the motherboard and replace it, after the first time you boot up your computer, go into BIOS and set everything the way it should be for your computer (usually just time and date) and then after each sequential time you reboot, that should take care of your problem.

Cmos checksum error & keyboard not function


CMOS checksum errors
Explanation: A checksum is computed as an error-detecting code, to protect the BIOS settings stored in the CMOS memory. Each time the system is booted this number is recomputed and checked against the stored value. If they do not match, an error message is generated to tell you that the CMOS memory contents may have been corrupted and therefore some settings may be wrong. BIOSes react in different ways to encountering this sort of error. Some will warn the user and then continue on with whatever settings were in the CMOS. Others will assume that the settings that were in the CMOS were corrupted and will load default values stored in the BIOS chip "for safety reasons". The error message will indicate which your system is doing.
Diagnosis: The most common cause of checksum errors in CMOS is a battery that is losing power. Viruses can also affect CMOS settings, and motherboard problems can also affect the stored values.
Recommendation: Follow the instructions in this section to address the CMOS corruption. You should make sure that all of the BIOS settings in the system are correct, by rebooting the system, going into BIOS setup and double-checking all the values (hopefully against a recent BIOS settings backup).

First system cmos checksum bad.. now laptop wont turn on


The Toshiba Satellite A210 computer is a piece of ****. I have only had my computer for 2 years and I am having the same problem. Everyplace that I have taken it to says that the problem is the CMOS battery. The CMOS battery is dead and needs to be replaced. That is why you cannot get through the boot process. Nothing is wrong with the hardrive, motherboard etc. All you need is a new CMOS battery. But guess what? When Toshiba manufactured the product, they welded the CMOS battery to the motherboard. So to replace the CMOS battery, you need to buy a new motherboard. Does this make any sense to you? All batteries eventually die and will need to be replaced. Why would any manufacturer in their right mind weld down a battery? Toshiba is trying to say that it is normal to design a computer this way. But in fact, it is not. HP's CMOS battery is located outside the motherboard and can actually be replaced by he average Joe lay person. And if you start comparing the design of other brands of computers to Toshiba's you will see that is not the case. The design of the Toshiba Satellite A210 is seriously flawed. It is the equivalent of designing a camera (before the days of digital) and gluing the film inside it. As soon as the exposures on that film runs out, you have no choice but to buy a new computer. And that is what has happened here. If I were you, I would get on Toshiba’s case day and night. What they have done, in my opinion, is misrepresentation and fraud. The have created, marketed and sold a disposable computer as a top quality product. But they forget to disclose one important fact about what they sold. That is disposable and because of its design, the lifespan of the product is dependent on the lifespan of the battery. I am currently arguing with Toshiba to try to get them to take ownership of this situation and fix my computer. Get on their case cause what they have done is not right.

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.

Turn on computer and message reads ****bad check sum (CMOS) ****


That means that after computer had been off for a long time the CMOS battery has drained, and CMOS (BIOS) settings had been reset to default.

Usually the computer will work fine after pressing F1, but you may get wrong date and time.

Try charging battery completely, often the problem disappears, if it does not , then the choice is between pressing F1 each time you start the laptop, or disassembling the laptop and replacing CMOS internal coin battery, located on the lower side of the motherboard.
