SOURCE: Have to set date n time on every start of my computer.Already replaced the battery of the board.But no fruitfull result!

Perhaps the CMOS jumper is in the incorrect position, making poor contact, or there is no CMOS jumper at all.

You can probably get a jumper diagram online, by searching the model number. If you have that manual, then that will probably do as well. Just look for where it should be and then double check to make sure it is in the right position.

Another possible explanation would be circuitry damage, in which case you may have to buy a new motherboard. Somehow that battery is not giving the CMOS power.

And a far-fetched third explanation would be it was not "year-2000" compatible. LoL. Maybe it freaks out on the date... Just random speculation though.

SOURCE: the time and date keep changing to April 11, 2016,

if it's not the CMOS, i would guess an application or utility is changing your clock.

After booting always to F1

The F1 key is often a notice that something is not right in the part of the computer that runs before the operating system (i.e. Windows). What is wrong is usually displayed in the rest of the message. It might be that your "floppy" drive is not working (you may not even have one), or that the "date and time" are not set, or that the chip that sets up your system before Windows starts has been reset to incorrect settings for your configuration.

On most systems there is a key you need to push, usually the DEL key, as the system first starts. (It may also be the F10, F2 or F1) Push that key several times...about 1 time a you start the system. This should take you to the BIOS screen (BIOS being the name of the chip that runs everything before Windows takes over). In there you can look at the date and time...if they are not current, or close to current, your BIOS chip has a problem. If they are current, if you restart and carefully read the message that came up with the F1 key you will know where to look in the BIOS to fix the setting.

If the date and time are not correct you need to have the CMOS battery replaced. This is not the main laptop battery, but the little watch battery used to keep the date and time (and other settings needed) when you have shut the system off and/or disconnected the larger laptop battery.

If it's this problem...the time and date will probably want to take it into a shop and have them change the battery. The little CMOS battery is only a few dollars (under $10) and the labor should be reasonable if that's all that is needed.

My Gateway laptop won't boot up it keeps saying "failure configuring Windows updates reverting changes" Do not turn off your computer

Make sure the Date & Time are set correctly on your machine. That can interfere with Windows Update. If your computer has the wrong date/time, you need a new cmos battery (available anywhere). Then, If you are running Windows 7, try the "Windows Update - Reset" options here...

Clock problem when i open the system

If the Date & Time changes back to some previous date when you next boot up the computer then the CMOS battery is worn out and needs to be replaced. After replacing the CMOS battery go into the BIOS and set the Date 7 Time.

How can I get into the BIOS to change boot sequence when I don't have the password

Remove the power cord, remove the battery and then remove the CMOS Battery which is normally attached to the motherboard. Most times you will have to disassemble the laptop to get to the cmos battery. Once you remove it let the computer sit for an hour or so and it will forget the date, time and passwords without that cmos battery being in. Put the battery back in after time elapses then see what happens.

How do I change the battery on the motherboard of Toshiba 4600?

BSOD's (Blue Screen of Death) on the 4600 series almost exclusively come from bad memory sockets (you have two), while the RTC issue (date/time) is un-related. Only in extreme rare cases have I seen both memory sockets go bad - so you can probably get around one bad socket by using only the "other" socket. The memory compartment is at the bottom, square big door covering it held in by 2 screws.

The RTC battery (CMOS battery) requires separation of the lower case, as it's located between the main battery and the palmrest. To get to it:
1. remove all bottom screws labelled B16 and B6 (including ones within the battery compartment);
2. remove the 2 screws in the back of the laptop;
3. remove the keyboard cover strip above the keyboard;
4. remove the 2 screws holding the keyboard, disconnect and remove keyboard;
5. remove the 3 (B16) long screws on the left half, and the 2 short screws behind the CD-ROM drive.
6. disconnect video cable, floppy cable, and mouse cables, and wireless antennas.
7. now you can separate the lower case from the upper case/screen assy. You'll see the RTC (cmos) battery - it should be dressed in green with two wires (red/blk) connecting it to the motherboard.

That's should be it. I'm citing all this by heart, so forgive me if I miss a screw here or there.... :-)

Forgot my password on my laptop it is in the bios and I can't remember how to get into the bios to change it

If you forgot your BIOS password, then you can reset it by clearing the CMOS settings. Do to that, you have to remove a small battery present onto the motherboard in your laptop. Remove the back panel of your laptop and locate your motherboard carefully. There you can find a small coin sized battery which provides power to the CMOS to remember your system date, password and other settings. Remove that battery from your motherboard and replace it back after 15 mins. Then fix the panel back and restart your system. It will prompt you for setting up BIOS or to restore default settings. Now your password should also be cleared. I hope this solves your problem.
