Laptops Access Bios Settings Key

I have a problem that looks like this one.

At boot up, after the POST, each time the HDD led blinks, the laptop produces a loud "beep", and refuses to boot, as if this phenomenon prevented the HDD to be read.

If I press the power button, it stops beeping. When I release it, it starts beeping again.

If I press F8 at the beginning and then ask for a normal boot, It boots normally. Anyway, in windows, I have some strange activity, like I would continually pressing Alt+Tab. If I press Esc, it stops immediately and then all seems to work fine.

Any clue?

1.) Unplug AC, take out the main battery.

2.) Take out /disconnect the RTC (real time clock) battery for app. half an hour (the period of 5 min as specified in the MSG normally is not long enough).

3.) Plug in the AC adapter (batteries still removed); computer should boot automatically, if not use the power button.

4.) The machine will boot and show the 162-error-msg "system options not set". Use F1 to save the settings.

5.) Shut down the computer and disconnect AC power again.
6.) Re-connect the RTC-battery.
7.) Install the battery pack(s).
8.) Restart the computer.

Try this, Remove battery, Remove RAM, wait... 5 mins, replace the RAM, Then, Plug in the Power supply ONLY. Now press and hold the Power Switch. It should come on.. When/if it does, Shut down as normal, and replace the battery and try again... If it doesn't work now with battery, battery is faulty, or too flat to be any good.. Try an 8 hour, or overnight charge. & try again, if still no good, it is a battery problem,. If not. then you have another sort of problem that you will have to troubleshoot.

1>Take the battery out of the computer, unplug all external devices, and disconnect the ac adapter i.e there has to be no power source to the computer.
2>Press and hold the power button for 1 min and then put the battery in and connect the ac adapter
3>Start the computer and start tapping on f10 key till you get the BIOS screen, (grey screen with system informatiom, configuration ,... and etc on the top), press f9 and then press f10 to exit
4>If the issue is still not resolved ,start tapping on esc( may be del if not esc) as you restart the computer and select boot from hdd.

The sympton is rather vague, but I suggest the following options, to be followed one by one, until one of them works for you.

1) Boot your system in Safe Mode (if Windows is your OS) by pressing F8 after the usual "beep" provided by the BIOS after it detects all is fine. If it boots up, which takes a little longer than usual, then your system is probably Ok, although it may have a configuration problem.
Reboot the machine from the shut down menu and hopefully it will work Ok. If not, then, depending on whether you have Windows Vista (or better), try:

2) Boot again pressing the F8 key, but this time locate the option that reads something like "Last known good configuration". Highlight it with the arrow keys and press Enter.
If you have System Restore set on your drive(s) your laptop should boot up normally.

3) The last option would be for you to go into your system BIOS and run at least a HD detection test, followed by a memory test, etc., but I would only recommend doing this if you know what you're doing. If not, ask a friend for help.

Press and hold the power key. It should shut down (or just pull the power).
Restart the PC and do not press the escape key

Change the bios battery.Remove the notebook battery and then you should see the bios battery.Maybe you should have to disassembly the complete pc because it is a little dificult without disassembly.

Hi, usually to get into bios on a toshiba laptop you press and hold the Esc key or the F1 key. try both of these, if they dont work, try this: 1. Turn on computer by Holding down power button while pressing the ESC key. The machine will beep, then display: Check System, then press [F1] key. 2. Release ESC key 3. Press F1 key If none of these work, we may have a different problem all together, get back to me if so, and i will see if we can find a solution. Hope this helps! Si :)

Normally 3 beeps then 1 is a checksum error, which is related to memory size/types and/or timings being reported as an error in the bios. Try also running in safe mode (F8) on start up and see if you get the beeps; because being able to start it up with an external monitor may mean that the memory error is related to amount that is used for your integrated graphics or a graphics driver error.
