Re: setup eroor

There is a i2c EEPROM ( not the BIOS rom memory ) where the checksum of bios and settings is stored. It's often 24C01 or a member family 24C0X . A picture can be see at

There is two possibilities:

1 _ Reset notebook to factory defaults to restore default options of cmos bios setup. There is a hole on botton side, see the manual where is and how to reset it. Connect it "in circuit" with a i2c "in circuit" programmer ( see SPI ), for example PONYPROG interface to a serial from another computer and write the right checksum for other identical notebook ( same model AND same bios version ), also resetted to factory defaults.

2 _ Exchange the IC. If the firmware detect a empty IC there is A CHANCE that it reprogram itself. I was write "a chance" because this depend of version of bios. You will need a hot air desoldering station, often used for fix cell phones, PDAs and expertise, care and patience to do this.

I'm have a thinkpad t23 with same problem, when I resolv this I'll post more info about this issue.

Re: setup eroor

This won't fix your problem but did wanted to put my input. This error basically means bad bios. IBM suggestion is to replace the board but ofcourse that is expensive. Keep me updated on any solutions you find. Somehow you need to flash your bios.

How to skip bios setup

F2 is your BIOS Setup enter key?

As SOON as you press the Power On button, start tapping on the F2 key.
Tap in 2 second intervals.
You may hear beeps. These are Stuck Key Error code beeps. You know what they are now, so just ignore them.

The BIOS Setup screen goes by F-A-S-T. You have a very small window of opportunity. This is why you are tapping on the enter BIOS Setup key, as soon as you turn the laptop on.

In BIOS Setup there is an option to bypass the P.O.S.T screen.

What is the boot up sequence please

You need to go inside BIOS to find out whats the boot sequence. To activate the BIOS Utility, press F2 during POST (when “Press <F2> to enter Setup” message is prompted on the bottom of screen).
Press F2 to enter setup. The default parameter of F12 Boot Menu is set to “disabled”. If you want to change boot device without entering BIOS Setup Utility, please set the parameter to “enabled”.
Press <F12> during POST to enter multi-boot menu. In this menu, user can change boot device without entering BIOS SETUP Utility. Navigate to BOOT page on top.

Hope this helps!

I have had problems finding a power cord that works. The original cord died and replacements give eroors

If you are not using a Dell Branded power cord, the system will give an error due to non-Dell AC adapters do not have the sensing circuit needed for the system to ID the adapter.
If you are using Dell Branded replacement AC adapters, then you most likely have a bad power connector on the motherboard.
