Question about IBM ThinkPad A21m 2628 Notebook

System Each time I unplug and replug my laptop in and start it up, the system seems to be "forgetting" the correct set-up for the date/time. I have to manually reenter it before the laptop will continue to start up.

    Actually, this happened after I replaced the c-mos battery.

  • cidergirl Feb 07, 2008

    The current battery is brand new.

    Are you referring to the little yellow round battery? If so, it is brand new. I put it in about a month ago. Since that time I have to reenter the date and time before continuing with boot-up.

The internal battery needs replacing. Must be the original and they die after a time.

The system clock will not stay set, when I turn off laptop the clock stops and calendar stops . I reset it every time I turn it back on so I receive all up to date updates . Windows updates are set to ...


You need to set the correct date and time in your system BIOS. To access that you need to press the correct key when the computer is first booted (usually DEL or F10/F2/F11).
Most computers will have a message stating press xx Key to enter setup or etc.
If this problem persists even after setting the correct time in your BIOS, your laptop needs a new CMOS battery. I recommend having a professional do this.

My acer aspire 5520 when i press power fan comes up then shut


From your brief description, it seems that your hardware is starting correctly, and then it tries to load Windows. Windows then fails to load fully, and so Windows forces the computer to restart.

So, turn the computer on.
Immediately press F8 (again and again) until a "start-up" menu is displayed. Select "Safe Mode" and see if Windows will start.

If it does, use the "System Restore" application within "System Tools" within "Accessories" to go "back-in-time" to a date/time when your computer *was* working correctly. Restore to that date/time.

Last six i didn't use my dell gx270 now i forget its bios password .Plz help me


You'll have to remove the the RTC clock battery to reset the BIOS, it's located on your motherboard. It's usually a coin-sized metallic thingy placed in a holder.

Unplug the power cord, remove the battery and push the frontside power button a couple of times to bleed it, then leave it for 5 minutes. Then replug it and start it up without the battery and check that it's reset (i.e. you should now be able to enter the BIOS hassle free).
If it's not the case, reboot the computer and repeat.

Turn it off and unplug it again and put the RTC battery back in place, and don't forget to set the time and date since it's now reset.

Will laptop work with dead cmos battery?


Yes, but each time you start the computer you have to enter the BIOS to set the proper time and date. This is essential for certain progra,s to run correctly, when the computer shuts off, everything will be reset once more.

This is the REAL TIME CLOCK power supply inside your laptop.It maintains the system configuration and clock/calendar.

Connect the AC adaptor and let it charge for at least 24hrs. Press F2 to enter the bios. Set correct time and date If it Persists take it to a dealer to be replaced

My computer went back to older clock date as 1610


try starting your computer in safe mode and see if you can do anything productive there, like scanning for viruses or spyware. also check if you can do the following:
CTRL+ALT+DEL (open task manager)
goto Start>Run>Regedit (open registry editor)
goto Start>Control Panel>Display>Properties (change display settings)
right click on clock at tray and change the current time to correct settings

if you cannot do any of these activities, then your computer may probably been compromised by a virus or malware.
