    gateway lp2407 problems

    Hi guys my name is chirs, I'm new to the site. I'm also a newbe, resently been toying around with electronic and fixed a few so purchase a broken gateway monitor in which the buttons light up and plays music on start up, but there is no display or backlight working. Form reading on the internet I Thought would be an easy fix so I bought a kit and installed all new capasitors (except for the tiny ones cause the kit did not include those) well as you can guess it did not work. It maybe my solder, like I said i'm new to this. Can someone give me any further advise? Here are some pictures and a link to my photo album if the pics don't show up. Any help would be great

              Check the fuse on the inverter board. A good fuse should measure less than 1.0 ohms.

                  Did you replace those Su'scon caps on PSU at c867 & c868?

                  Try replacing the 47 uf 50V and the TEAPO next to the rubycon on PSU as well.

                  In image img8492u, The Panasonic cap on the inverter board to the right is folded 90 degrees this could create a poor connection or damage the leads in the cap.

                  Also found a thread dated a year old, it may help or not. But take inconsideration that there are different designs and revisions of boards so what may work in this thread may not work for you.

                                      USB problems?
                                      by Hondaman
                                      Recently I discovered my SSD died (OCZ/Toshiba 240 GB). It was in a USB enclosure, attached to the Linksys WRT-AC1200 router. Since then I removed the USB enclosure and attached it to my Win7 PC (AMD 8150 CPU, 970 chipset, 64 GB RAM). I also gathered one or two other USB enclosures to figure out what is going on.

                                      (I suspect that I lost quite a few MP3 and FLAC files I recently ripped from my audio CDs, I think I lost very little un-replaceable stuff.)

                                      I think it is IMPOSSIBLE for Win7 to have any problems with a USB enclosure as long as Win7 knows how to speak to the...

                                      Lenovo 11e problems (any sata hdds are not recognized, sleep battery drain)
                                      by clabr
                                      Need help to solve some problems with this laptop.

                                      After working in bed with it one night and heating up too much (probably the cause of this problems) the sata HDD OS windows froze
                                      After restart the original Sata HDD was not recognized anymore (but works fine in other laptops or PCs)

                                      Tried connecting other good Sata 2.5 HDDs but not one is working in this laptop anymore (not the original nor others)

                                      Before this had happened I observed some other problems:
                                      When I tried replacing original mecanical HDD with a SSD HDD could not get them...

                                      Greetings everyone,

                                      I have a Gateway P5WS0/NV57H58u laptop (P5WEO LA-6901P REV:2.0). The client said the battery was not charging. Upon checking the laptop,

                                      1) On pressing the power button, the (power button) light turns on and stays on.
                                      2) There is no boot, or anything on the screen.
                                      3) The fan starts and stops a few times, then it stops completely.
                                      4) The light on the power button remains on.
                                      5) Battery not charging (original issue).

                                      The original problem was that the battery was not charging, but the laptop still worked. My belief                                      ...
