push the power button at the same time with thinkpad button, and fast press F1 key.
you should need to do this 3 times to fix the problem.

There could be a fault which may mean you have to replace the drive but first try a cd lens cleaning disk and if you have some, open the disk drawer and give the inside of the drive a blast of compressed air.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

Hi

would you like to expain what you are trying to learn or what you would like to do
with your laptop
also what operating system are you using is it xp or vista or windows 7


many thanks

first: do you have a wifi-capable router? ensure that you do, and that it is hooked up properly.
next, are you sure your laptop is capable of wifi?
if there is a wifi switch on your laptop, flip it to the on position.

if you're running windows:
right click on the taskbar. you should see a signal/strength bar either with a red X or a gold circle.
if it's a gold circle, right click. find your enabled wifi router name, and connect.

Make sure the battery contacts are clean. If it won't hold a charge then you probably need a new battery. Batteries only last a couple of years.

This is a tricky problem, you need to troubleshoot this bit by bit - first take the memory out one stick at a time and try to turn it on each time, then try the hard drive. If it boots further with one of these things out then you know thats the problem. If it still doesnt boot after trying these components then you need a repair as it will be an onboard component.
My immediate guess would be the onboard power supply unit, unless your charger is broken and you can test with another charger to rule that out too.

problem is with the motherboard or wrong power

if your using an office internet connection use the proxy server to connect..

> CRC

Cyclic Redundancy Check

When you write a block of data to the disk-drive, a 'CRC' value is calculated, based on the data, and both the 'data' and the 'CRC' are written to the disk-drive. When you ask to read that 'data', both the 'data' and the 'CRC' are read. The 'CRC' is recalculated, based on the data actually read. The "new" CRC is checked against the "old" CRC. If there is a mismatch, you have a 'CRC check' event, implying that the data you wrote could *NOT* be accurately retrieved.

So, it's probable that your disk-drive is "dying" -- it cannot accurately store your data. Replace it.

Turn the computer off.
Turn the computer on, and immediately look for a message on the screen, e.g.,

press <blah> to enter BIOS SETUP

or

press Enter to interrupt normal startup

Press the specified key. Then, choose to enter BIOS SETUP.

Use the arrow-keys on the keyboard to navigate to 'LOAD BIOS DEFAULTS'.

To reload those settings, just press the Enter key.

Just like any other Windows. That is to say, insert he Windows Installer CD and power up. Boot from the CD and follow the instructions. Answer some questions and supply the correct Serial Number and after two reboots you have Windows 2000.

keep pushing f2 when page comes up change your boot log f12 restart computer push f12 rerun windows.

Sounds like your power supply unit (PSU) is broken, do you get any lights come on when you plug in the DC cable and try to switch on?

try with a new and also valid battery.
your battery is damaged or it's life time is come.
so buy a new battery.
if it doesn't work the power chips of your notebook is damaged so take it to a guarantee center.
