Try accessing the BIOS settings and set to a complete initial test (slower startup). If the computer turns off before completing the initial test (POST), then there is an hardware fault. In that case try starting the computer with no battery inside (only charger); try replacing memory modules; disassemble and start the computer with disc units and built in keyboard/pad not connected.

Hi,
First, not that the keyboard is held by two long screws (as marked in the picture below), which are to be opened from the bottom.


After removing the battery and bottom screws, you have to remove the top cover (near LCD hinges, above keyboard). After that you would be able to pull the keyboard and remove the connecting ribbon cable to detach it. Below is a video for Laptop keyboard replacement.

There is a latch that you need to pull to seperate the keyboard base from the slate tablet pc. This latch is located behind the monitor where the keyboard attaches to the monitor.

This guide is to provide some help for those who want to disassemble their laptop.
You have to be sure that the problem you face is from the hardware, and that your laptop is not under warranty, since that laptop disassembly void warranty.
Search on the net for service manuals some are free and other cost around 6$ . Not find your model ? download some free service manual from different brands and read them many steps are the same in laptop disassembly. But i do recommended to find the manual that fit your laptop because you may need to know the part number of the defective part to change it.
Now you have to prepare a clean working area with small box for the different parts and their screws, and maybe a pen and a paper to remember particular step.
To disassemble the computer, you need the tools below:
Wrist ground strap and conductive mat for preventing electrostatic discharge
Small Phillips screw driver
Flat head screw driver
Hexagonal driver
Tweezers
NOTE : The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding components to avoid mismatch when putting back the components.
When you remove the stripe cover, please be careful not to scrape the cover.
In most of laptop you can actually access by the base to these bays :
battery
memory
hard disk
Remove them all, to remove the optical disk just release the screw securing the optical disk module,push the ODD module using a screwdriver and remove the ODD module from the main unit.
After that look on the keyboard area to find how to remove the keyboard for example with an Acer aspire 5100, you have to remove the middle cover from the edge of the middle cover and carefully detach the middle cover, then you just have to release the two screws securing the keyboard plate and carefully detach the keyboard plate from the edge of the keyboard plate finish by release the keyboard FFC lock carefully because it is fragile. Then remove the keyboard plate.
After that you can either disassembly the lcd module or try to access the motherboard.
For the LCD module carefully disconnect the LCD cable and any other cable that you can see, release any screws holding the LCD module on the bottom side of the main unit, release any other screws securing the LCD hinges on the main unit, then detach the LCD module from the main unit.
For the motherboard every model are different then you have to explore by yourself, but not forget to read some service manuals before.
You can find some free service manuals at laptop support.
I hope that this will give some help.

The problem is likely the solenoid that diverts the water from the washer arms to the drain.  It is located in the motor areal of the unit and is connected to the waste line.  It is either defective or clogged.  Many of these units can be disassembled and cleaned.  Try that first.  If not, replacement is not difficult.
