My ibm laptop model cannot be opened nor turn on, we tried to open the back portion of it but we can't do it because we don't have a manual. i wasn't able to brought my laptop to the technician. how can i solve that problem?

the air ducts could still have ice in them,remove the bottom kick panel,you should find a tech sheet either on the kick panel or taped in the cabinet area down there and it will tell you how to manually put your fridge into defrost, you don't want to work on it while it's running or you'll make it worse,you'll know it's in defrost when the compressor shuts down and the fan in the freezer stops blowing if you can't find it shut down the fridge or unplug it again,remove the food from the freezer,if you're handy remove the back inside wall of the freezer and with a hair dryer melt out any ice up in the vents and blow the air from the hair dryer up above the fan motor and in the corners, ,you'll see water dripping where the ice is,heat it up until no more water drips down,hit one side for a few minutes and then the other side for like 5 minutes at a time so you don't damage anything from heating it up to much,or if you have another fridge leave it unplugged for a couple of days.if you can't remove the wall blow the air into the air slots in the back wall panel,in the right and left side corners and then in the middle,have a light or flash light,you should be able to see water dripping down,keep blowing the air in until no more water is dripping,might take you like 30 to 45 minutes to do this,then turn it back on and see if you can feel cold air blowing into the fridge section,if not shut it down and heat it up again,if you see water dripping there's still ice in there,all that happens is the evaporator coil in the freezer gets cold,the evap fan blows the cold air up nto the fridge section and the air returns to the freezer through the air ducts,when the door was open warm and cold air meet and forms ice in the air ducts,if the fan is working and depending on your model and next time you write send the model number you could have a damper it could of got damaged but it sounds like all you have is frozen air ducts

Check your Display in the Control Panel. Maybe you don't have it set to extend the display onto another monitor.

There is all kinds of file recovery software, go to www.ebay.com type lost file recovery, or restore files, you might get a portion of your files back or more, choosing the right software is critical.

Why does it not have a touchpad? Maybe the touchpad driver is not installed or the touchpad has been disabled or is toggled off.

First off, you can always use a usb mouse instead of the point stick.

Click Start/Control Panel and look for the Mouse and open it to check the mouse properties. Make sure you don't have the touchpad disabled.

Some models will allow you to toggle the touchpad on or off by clicking on the button that is located at the top of the touch pad in the middle.

Some models will allow you to toggle the touchpad by tapping twice in the upper left hand corner of the touchpad.

Some models will require a keystroke to toggle the touchpad. Press and Hold the ALT or FN function key located at the lower left portion of the keyboard, then hit the key that toggles the touchpad. The correct key to hit will have the icon of a finger pointing at a square that represents the touchpad.

Try downloading and installing the touchpad driver.

Get online and got to www.google.com In the google search box type: "IBM Support" or "Lenovo Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Download and install the Touchpad drivers.

Try unplugging the freezer and leave the door open for about 30 to 45 minutes. Don't forget the door is open and plug the freezer back in. Set a timer in the kitchen so you don't forget. Once you can open the drawers look inside the freezer sides to find the controller. Most models have turn dial inside.

Check if the light is green...but don't see anything in the monitor. If that happen your laptop may have hang peripherals like memory or processors...
try to open the location of the memory discard it and open the laptop in just 5 second then off...insert the memory now then test if it's ok...
If the laptop is totally no power...the power supply may be defective...please see a technician if you can't able to replace it...

Don't try to locate a hardware switch, this model has a software switch. In other words the wi-fi is not activated by the Fn+F5 combination. Try to locate an enable - disable switch at the IBM software toolbox.

Thanks and regards

Most T20 models did not have wireless built into the computers by default. You may have to add a wireless adapter to your computer. To verify whether or not you have a wireless card, open the middle cover on the back of your computer (with the computer unplugged and the battery removed) ... you should see a small card about the size of a business card next to an even smaller card. If the larger card has two antennae wires connected to it, you have wireless. If not, you don't have built in wireless and will have to use a USB or PC Card adapter.

Not know what model you have, I send you a link for the MMP8640:
