![]() ![]() I've tried these, but it either just shuts off or stays on a black screen when I do.Some ThinkPad fans have created Custom BIOSes to remove whitelists, disable annoying errors, do Fn-Ctrl keyswaps, and add more functionality. I've read about it on other models, where they usually short out the two bottom right pins. I've found what I think is the EEPROM, but i don't know which of the pins i should short out. I've read about resetting the EEPROM and this kind of stuff, and i've done it before on an older model, but i just can't seem to get it to work on the T470. So I'll have to find a way to unlock them. But well, the people who worked here before failed to write them down, so when we now got the laptops back we have no clue what the passwords are. A few years ago, we sent some computers down to the local prison, so we obviously locked the bios. Here, we are in charge of all the computers owned by our county. Hey!

When reinstalling Windows, try the Lenovo disc images, as longer battery times have been reported, probably due to custom drivers. A can of compressed air may be useful too, and a bottle of isopropyl alcohol and cotton buds are good for cleaning, but not on the screen. The only tools you need for servicing a ThinkPad are a set of small screwdrivers and a nylon spudger (for taking the screen and keyboard bezels off), and possibly a pair of tweezers. Corporate bulk purchasers don't usually go for it. Not only will it have better brightness, colour, contrast and viewing angles - you will most probably more than make up the investment when selling it. When buying a new ThinkPad, consider taking the IPS screen option if possible, as it doesn't cost much. When buying a used ThinkPad, remember to check that the BIOS is not locked with a supervisor's password and that Computrace is not enabled and activated.
