20 Most Recent Lenovo ThinkPad R400 Notebook Questions & Answers

Stuck key error means that one or more keys on the keyboard are stuck. It's possible that a liquid spill can also cause one or more keys to electrically "short" causing the error. Inspect the keyboard and check if any keys are mechanically stuck.
If you're mechanically handy you can remove the keyboard, inspect any chances of damage or corrosion. Plug it back and see if error is still occurring.
Reset BIOS to default settings. Perform Flee Power - remove the battery and any other peripheral device connected to the computer. Hold the power button for 10-15 seconds and then connect only the AC Adapter and turn ON the computer.

hi mmi300, try to press Fn + F5 and check if it works. Pls determine if there is a toggle switch (if it is a laptop) somewhere. Disregard that step if it is a desktop...

Hope this help...

The WEBcam driver needs to be installed first before you can access the WEBcam.
The same model ThinkPadcan have different types of network, video and audio drivers and unless youknow exactly which one is installed in your ThinkPad, you need to download allthe drivers and install each driver until you find the right driver. When you download thedrivers, write down the device driver and it's file name so you have a recordof which driver you are installing and which directory the unzipped files arelocated on your hard drive. Go to the IBM/Lenovo WEBsite - support/download page and download the latest Windows device drivers foryour model computer, Use this link: - http://www-307.ibm.com/pc/support/site.wss/product.do?template=%2Fproductselection%2Flandingpages%2FbrowseByProductLandingPage.vm&sitestyle=lenovo&brandind=10&validate=true

We ran a typical Thinkpad T400 battery of tests, including games, applications, and a couple other areas. Time constraints limited the amount of testing we could get done before the NDA lift (and it's already a few hours late), but we will be providing a follow-up article with further testing and information. That said, if there are any specific areas that you'd like to see tested, feel free to e-mail me or leave a comment.

Computers always boot from the hard drive.
The Bios on the mother board have a routine that tell it to boot from the Hard Drive, or USB in the BIOs setup.
to look at the BIOS setup, when you turn it on keep pressing the <ctrl><alt><del> keys on your key board, this should let you go into BIOs setup. there you can check which device it the first boot, second boot and third boot.
If your hard disk the boot, it is probably crashed, you will have to take it in to be repaired, and you might need a new hard disk.
in which case the repair shop will have to put in a new hard disk, format it as bootable, then reload the operating system, and any software you might have been using, so take into the shop all cd software disks with the computer to the shop so they can reload all your stuff. If there were any files you had on the disk, they may or maynot be recovered.

Good Luck...

Error 0250 means that the BIOS battery is dead and has to be changed, they are usually located hidden in the memory panel underneath the laptop and can be covered in red, blue or yellow plastic.

To boot into windows hit the F1 key when you see the IBM logo, go into the BIOS utility and set the time and date, save the changes and exit the BIOS, make sure you have AC power plugged in when you do this as it will not remember the time and date and you will have to do it again.

Good luck.
