After connecting [...]]]> The symptom was first seen just after a lightening strike where the laptop was disconnected from the mains however it was connected to an ADSL modem which in turn was connected to a PSTN telephone line.  This could have been the source of the Voltage spike that could have damaged the laptop.

After connecting the power supply to the laptop there was absolutely no power, not even the battery LED, it remains dead.  I removed the battery and tried with just the power supply but still no power up.  The battery was discharged so it was useless to check power up  on the battery however I still tried but nothing positive.

Dismantling procedure.

1. Unscrewed RAM compartment to remove RAM and to see if there were any hidden screws and in fact there are.
2. Removed the 2 CDROM screws to extract the cdrom from the main chassis.
3. Removed 13 screws from the bottom chassis another 2 from the RAM compartment and another 3 from the battry section.  three other screws were removed from the CDROM section.
4. Unclipped the 5 keyboard clips to remove the keyboard from the top chassis section.
5. 1 hidden screw was removed from under the keyboard.
6. Removed the connection cable for the touchpad from the motherboard.
7. Removed the top chassis entirely so no I could see the top part of the motherboard.
8. Removed 3 screws that connect the Mboard to the bottom chassis.
9. Removed cable clip from the top section which also held the video and WIFI cables.
10. Removed two hard drive screws to release mboard.
11. Unplugged video cables from the mboard and other minor connectors.
12. The mboard could now be removed.
13. No visible physical damage can be seen however I tested if power was actually reaching vital parts on the motherboard.

First and foremost it is important to remove the battery and any slot in memory cards that are present.  Remove also any Game in the drive.

The Guarantee seal will need to be remove since two screws are beneath it [...]]]> This article relates to the dis-assembly procedure of a Sony PSP-1004 model.

First and foremost it is important to remove the battery and any slot in memory cards that are present.  Remove also any Game in the drive.

The Guarantee seal will need to be remove since two screws are beneath it so start with these four screws which are present in the battery compartment.  Two other screws are present on the other side of the PSP.

The next screw that needs to be removed is the external screw just next to the side bar code between the speakers.

Once these are removed the rear panel can be unclipped.

Now the screen can easily be seen but to remove the LCD screen you must first un clip the button bar which resides just below the screen.  Use a screw driver to un-clip . There is no need to remove the cable from the main board.

Once done unclip the screen with the same screw driver and slowly remove the two cables.  Before you do this you need to first lift the connectors slowly because they can be snapped very eaily.  Once this is done the screen is released and can be changed.

The same procedure can be repeated reversly to close the PSP back.

Look at the images for a better view of the procedure.

So I first checked where the spill came [...]]]> An unlucky occurrence where the poor thing has undergone a water proof test which it seems it failed. I received this LAPTOP as new as it could be hardly ever used but it had been maltreated with soft drink and reported to never switch back on again.

So I first checked where the spill came from however it seemed that the splash has hit almost every vent. So here we go with the dismantling process of this Acer 4000 travelmate.
