Question about IBM ThinkPad R40 Notebook
Okay when i turn on the computer i have to push F12 right away because it is password locked at the time and when i push F12 to engage booting it says " system failure your pc has been tampered with "!! what now.
Havent opend one of those yet... Does it give you a code, something like a HEXADECIMAL code of some sort, if it does there are DOS programs that can be used to find the password or reset it.
other wise there is the option of opining the NB and removing the CMOS battery wicth should reset system. This I would not advise to you if you dont have a lot of expierince with Tech work.
How ever if you do decide to do this, please read up on Google about reset CMOS on that specific model, some models will lock untill it recieves a code that only IBN should have...
Hope it helps

Testimonial: "thanks appreciate it bye!!"
Removing the CMOS battery hasn't worked on laptops in years.
There is a Capacitor, or more than one, in the circuit.
A Capacitor stores a charge of power. It can store power for weeks, months, sometimes over a year.
For this application, almost indefinite. The miniscule amount of power needed, is measured in Milliamps, or even less.

According to info I have;
1) Laptop off, turn it over, set it on a table. (You may wish to place a soft Static free cloth on the table. Helps prevent scratching the table, and the laptop)

Both errors are related to the backup battery which is located under
the main battery. It is probably dead. You can get one on
eBay for $3.29 w/free shipping or pay a shop $20 to put one
in. If you do it yourself be very gentle plugging it into the
tricky little slot - it is possible to break the connector loose from
the motherboard but it is an easy repair if you have patience and
dexterity. As for the password, try just hitting enter. It
is the supervisor password to change the BIOS settings and was probably

This is caused by the small battery inside that keeps the time and date for the computer. If it is dead, you get the message you refer to. Sometimes they are easy to change, sometimes it is quite a hassle. If you go to setup, you can change the time and date for that session, but the next time it will be off again.

it sounds as if you have a hard drive failure, or the BIOS settings are messed up for some reason. Try going into BIOS by hitting F1 or F2 or F10 or Delete... or maybe your laptop has a special button for going into BIOS, and find the Boot Device Options to see if your hard drive is the first boot device. Also, you may want to check the Standard BIOS Settings and the PC configuration settings. The names of these settings depend on the BIOS version you have, but the bottom line is that you need to find a list of devices recognized on your laptop, and see if there is any entry for a primary hard drive. If there isnt a primary hard drive, find an option that does auto-detect of hard drives and run the detection sequence. If nothing comes up then your hard drive is probably dead or damaged, and you'll need to get hands-on help to deal with the problem.
