hi. i have got an E-System 3086 running on windows XP. i recently opened up my laptop to see if i could expand on it. To see how the things went together i took out the hard drive and the memory. I then obviously put every thing back together and started it up again and every thing was fine and it went into the OS and everything. however i then shut it down (correctly) and now it wont start up again (wont boot) I then tried taking out the memory again and putting it back in because i had the same issue with my desktop and that sorted my desktop out but i seemed to have no luck with the laptop. i also got some info from one of the other threads and took the memory and the battery out and repeatly pressed the power button cleaned the connectors of the memory and still no such luck.
If someone can help then i would be really grateful. Thanks

reported a one-time successful start after reassembly and then a failure to boot; rightly suggested checking connections. The next steps should be a short, methodical isolation sequence that moves beyond basic reseating and cleaning to rule in/out power rails, the board, RAM, and boot devices.

  • Measure the AC adapter output with a multimeter and compare to the sticker rating; inspect the DC jack for looseness, corrosion or broken solder joints. An intermittent jack can allow a single successful boot then fail.
  • Observe any power LEDs, fan spin or POST beeps. No activity at all points to power delivery or the power-button/power-ribbon circuit rather than the OS or hard drive.
  • Test memory by exercising one module per slot and swapping modules with a known-good stick where possible. If POST is reached, run memtest86 from USB to confirm RAM stability.
  • Disconnect the HDD/optical and attempt to reach the BIOS/POST; if BIOS is accessible, check drive detection and boot order or try a bootable USB to separate OS issues from hardware failure.
  • Inspect internally for misplaced standoffs or stray screws that can short the board, pinched ribbon cables (power button/keyboard), bent connector pins, or cracked solder joints around power components.
  • Try a CMOS reset (coin cell removal or jumper) to clear corrupt BIOS settings after a hardware change.

Static precautions are important: work on a nonconductive surface, ground before touching the board, and keep screws organized. If multimeter and spare-RAM tests are inconclusive, the fault commonly lies in the motherboard power circuitry or a damaged connector; at that point board repair or replacement is the practical next step.

double check maybe you have just miss something when you put back your laptop, check if there's any loss connection..if it was working fine before you take it apart..then maybe you didn't put it back properly...
