    I have USB and parallel port based dongles for removing BIOS passwords.
    These work on many makes/models of laptops, but not all.
    (Yes the p'port isn't used on laptops these days, but I still keep it for "oldies" )

    On the subject of a UPS, monitors aren't such an issue. It's laser printers you should never connect to a UPS
    Hmmm, I was always told both. But I did forget to mention laser printers also thank you.

    This is only what I've been told so I can see how it could be wrong. I've never tested it myself. I should've been more specific anyways I meant CRT's not LCD's. I just like to play it safe anyways and only use the UPS for the more sensitive equipment. I'll have to test this more.

    CRT's will not bother most UPii, except for being an extreme drain on battery power when the main fails. If you do lose power for an extended time, how are you going to see to shut your machine down if you don't have your monitor hooked up to a UPS?

    Of course, all the machines that we have here are connected via either USB or serial cable and are configured to auto-shutdown on power failure.
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

    It is not a PC lab, it's a Bio lab, we have actual real chemists working.

    Most security settings are stored in regular old volatile RAM...but this chip you mentioned may be a "flash" type or "non volatile memory" meaning that it saves this info until the next session. Or perhaps maybe theres an internal power supply elsewhere??


    Either way...have you tried a BIOS hex editor on it to remove the password?
    Some IBM/Lenovo units (T40 series and others) have a hardwired encryption chip. A hex editor will not remove the password, and removing the chip will render the laptop useless. Also, IBM will not reset it for anyone If you set it to prevent boot without the correct password, prevent accessing the BIOS w/o the password, and used to encrypt a section of the hard drive, it's about as effect as you can get.

    Even if it's stolen, the laptop can't be booted, and if the drive is placed in another machine, then the encrypted section of the drive can't be read. It's how my client files are kept secure.

    Hope for the power to be restored in time or auto configure a shutdown.

    As opposed to fake ones?

    Last summer a pole right across the street from our building just snapped off and fell into the road. The entire area was without power for at least two hours.

    At our plant, it isn't that much of a concern as we actually get power from both a primary and secondary grid, one comes from the north, the other comes from the south, each one is fed from a nuclear power plant. The UPii down there really only need to maintain power for the 10 seconds it takes to switch between the two grids. I got a little ambitious when I was calculating the size of UPS I'd need for a couple of the PLC's. It's hard to know how much current they draw, one of the UPS can stay running for 232 minutes and the other for 187 minutes.

    Yep, we don't like fake chemists.

    Fake Chemists don't last very long. They go *POOF*.
    I felt like bending the bars back, and ripping out the window frames and eating them. yes, eating them! Leaping, leaping, leaping! Colonics for everyone! All right! You dumb*sses. I'm a mental patient. I'm *supposed* to act out!

    APC have a quite nice "calculator" for assessing your UPS requirements.
    It's freely available on their website. It's also just as useful for gaining your required specs, even if you aren't going to go with APC for the purchase. It will at least point you to the right ballpark, as it where....

    As for monitors, although most UPS's are "smart" devices these days and save open files and close machines down gracefully, it is still very common to use a monitor also. Although these days it is mostly going to be LCD rather than CRT, admittedly.

    Anyway, as for laser printers, I meant to mention that many higher end UPS's have a separate socket for laser printers and the like. It's basically a "pass-through" port, so you can still benefit from power conditioning, but minus the power backup.

    Yeah, I've used the calculator before, sometimes it's rough though when you're trying to aggregate maybe 20 different devices in a cabinet.

    I really like APC's NetSNMP cards for their larger units. I have them scattered around, makes it nice and easy to monitor.
