Hey all,

I'm attempting to work on a customers laptop and am completely stumped. I was told that it was working fine until he installed software for his iPod. The installation told him to reboot and now it won't power up at all. The battery seems to be fully charged and with or without the ac adapter the blue lights flash for a split second then nothing. Any advice would be tremendously appreciated!

Thanks,
Matt

opened this thread and reported a similar symptom; already pointed toward memory and storage as possible causes. The notes below add a compact, prioritized diagnostic sequence and board-level checks that often clarify whether the fault is a cheap part or a failing system board.

Begin with the power subsystem. Verify the AC adapter actually produces its rated DC with a multimeter or a known-good replacement. Check the barrel connector for looseness or intermittent contact. Perform an embedded-controller/power reset by removing all power (battery and adapter) and holding the power button for 30-60 seconds to drain capacitors; then apply adapter only and observe any LED, fan, or drive activity. Some Pavilion models have a recessed reset pinhole on the underside; consult the service guide for location before using it.

Open the chassis only after the unit is unplugged and the battery is removed. Inspect the DC-in area and nearby power circuitry for cracked solder joints, burnt components, or bulging electrolytic capacitors. If comfortable with electronics, check primary board power rails at test points with a meter; missing or shorted rails point to regulator/MOSFET failures that require board repair. Photograph connector locations before disconnecting anything.

If basic power and visual checks do not restore life, attempt a minimal-boot isolation: start with the absolute minimum hardware fitted (one memory module, no drives, no cards) to look for POST activity or fan spin. If the board remains dead, recover the hard drive by connecting it to a desktop via a SATA-to-USB adapter for data backup, then weigh the cost of a replacement system board or professional board-level repair versus the laptop value. Safety note: practice ESD precautions and remove power sources before any internal work.

Hi guys i ahve just finished a repair on a ze4700 series and a ze5600 series laptops and both of them had indentical errors..on the 4700 series i found the problem to be no more than a bad stick of memory, try reseating it if that doesnt work replace the stick, you can also try the reset button that this series of laptop has because on the 5600 series i repaired it was due to a corrupt OS on the Hard Drive i found that when i inserted another hard drive OS ready it would boot up to bios fine and load the OS without problems, but that hard drive that was in there originally just would not work, i had to connect the original Hard Drive to my PC and Remove the data before doing a full format then it loaded and installed the OS straight away, i think before you install anything on these series laptops make sure to flash the bios with the most recent version you can and make a back up disk because i fear it may be more common than we think, the ze5600 series laptop i have no disassembled and am selling as replacement parts on the almighty Ebay and the 4600 i have kept to sell as a unit and have been installing lots of programs on to test it to its full, the only program i have had trouble with up to now is google Earth Pro, seems when ever i try to run it i get a blue screen error and laptop shuts down so i would advise to stay clear of that one as i have not gotten to the bottom of it yet...matter of time though unless someone takes it off my hands first
Hope this info may help a little
Take care and good luck...let me kow how you get on
