    Sony VPCSE turns off instantly after turning on

    Hi guys, I have an Sony VPCSE (1E1E) that turns off right after it displays the bios logo.
    It turns on, displays the BIOS logo, and than simply shuts it self off. Same result every time you try to turn it on, even when you hold the button or close the lid. This was first noticed on battery. Same thing happens on charger and on charger with out battery, as well as with out hard disk. Sounds like it is having Intel ME region issues.

    Laptop doesn´t do this always, but when it does happen you cant turn it on.
    Thermal paste was replaced and BIOS was updated. The laptop is generally in a very good shape (internally).

    Also I can´t seem to get the graphics switch to work properly.

    Can you please help?

      it could be a bad southbridge, not intel me region. what southbridge it has ? is is nb+sb or just the intel small chip? if so intel chip could need to be reballed (not reflow, that will not work)

              I think it has something to do with some sort of software because this started happening after I used AMD clean uninstall utility to remove all AMD software from the computer , as it stopped returning the HD6630 GPU back into function (And into device manager) , when i flipped the switch back from Stamina to Speed (Intel to AMD). I did this yesterday at night and when I got to it in the morning it started happening.

              This also happened before two times but it started working on its own again. I know it is not the switches as it happened once more when i started the computer VIA jumper and without the buttons and keyboard.

              Chipset is intel HM67 , CPU is Intel Core i5-2450 , GPU is HD6630M w/1GB.
              Bios has been updated VIA Sony update tool.

              I also had issues with the Renesas uDP720200AF1 USB 3.0 firmware I had to take out firmware from an similar laptop - VPCSB1A9E.

                      u think is software, but without hard disk wich software should cause this ? no sense

                      as i said or bad sb, bios, nb , ram, power circuit (check if first 2 mosfet of dc in circuit get the right gate value and if they get hot.

                          by sabretooth
                          Hi all,

                          I have a Sony Bravia KD-60X6700E which has decided to stop working. To describe the symptoms - it just decided to stop powering on one morning. No standby LED, no sounds, no picture, no startup logo - nothing. Doesn't respond to the remote nor the physical power button on the unit.

                          I have tested the power cable for continuity. I have also tested the fuse, and that too, has continuity. However I haven't gotten much further with the probing. I've prodded the secondary side of the power supply where the connector connects to the main board, and there's no voltage...

                          Sony XBR-55X930D Magically turns itself on
                          by Topcat
                          I got paid to take this. It had the typical bad STBY IC on the DPS board. Replace it and life was grand....or so I thought. I've never seen this one before; this TV will just magically turns itself on for no particular reason on earth. I did a hard reset on it (twice) clearing all data & settings out.....will still do this. Even removed the batteries from the remote....in the unlikely even there was a stuck key... Still doing it. I did not set up any of the 'smart' functions, I just fed it a source from a HTPC. It doesn't matter what input is selected.....still does it. No rhyme or reason...

                          PS3 Slim Turns OFF Immediately After Turning ON
                          by Stanley1843
                          Hi, my PS3 Slim (CECH-3003A) when I connected to 230V the PS3 the indicator of the switch is red and after pressing it the is green (fan spins) for only 10 seconds and then completely off. Some times also is completely off when I connected to 230V.
                          On the CN101 connector at the 5VSB pin I measure 0V.
                          Without the CN101 connector pluged in the PS3 board (on the fly) I am measuring 5V on the 5VSB on the power supply side.
                          On the 5VSB in respect to ground I am measuring 6 Ohm resistance. There is any schematic to find which ICs supplied from 5VSB or any suggestions where l have to...
