I have had this Dell 8600 for several years. It has withstood being dropped numerous times and I even accidentally poured two cups of boiling water on top of the keyboard over a year ago.

What did it in was my 2008 Streets and Trips Pharos USB GPS unit. I snapped off the USB part of the gps in my usb port. There must have been a surge when this happened and now the Dell won't power on.

When I try to power it on the power light turns on for about 5 seconds and then goes off.

Could someone kindly let me know if there is something simple I can try to recover it, or do I need to have the motherboard replaced?

I know it sounds dumb, but I cried terribly when it died. After I poured the boiling water on it it blitzed out of course. I made a dash to Best Buy and bought a new Toshiba to keep our business going. After three days I remembered a cd that was in the drive of the Dell. When I opened it up to get the cd it powered on. Thankfully.....the Toshiba has been a lemon. It has been sent off 3 times and crapped out again the other day (I'm making my husband take it into Best Buy this time, I'm afraid I will throw it at them). I had to buy ANOTHER laptop to keep the business going and this time bought another Dell. I would really like to get my old Dell fixed too.

If anyone has any suggestions I would truly appreciate it!

Targeted steps for a Dell Inspiron 8600 that lights for a few seconds then dies after a USB connector was sheared (for @Member257523). As noted, general power checks are useful — below are focused, practical checks you can do before deciding on a motherboard replacement.

  • Power-reset and isolation: remove battery and AC, press-and-hold the power button 20–30 seconds to drain caps, then plug in AC only and try to start. If it behaves differently with AC-only versus battery-only, that points to the adapter or battery.

  • Check the adapter: measure the adapter output with a multimeter or try a known-good Dell adapter with the same voltage/amperage. A bad adapter can make the machine start briefly then shut down.

  • Minimal boot (breadboard): remove HDD, optical drive, Wi-Fi card, PCMCIA/ExpressCard, and all but one RAM stick. Try each RAM module in each slot. If the laptop stays on with a minimal set, a peripheral or memory slot is the problem.

  • Inspect the USB/board area: with power removed, open the case and look for burn marks, melted plastic, loose metal fragments from the snapped USB, or damaged traces near the USB and power circuitry. A shorted USB 5V rail or a blown SMD fuse/MOSFET will often cause the symptoms you describe. Do not power it if you see significant damage; leave that to a repair tech.

  • Reset CMOS/EC: remove the coin cell (if accessible) for a few minutes, then reassemble and try again. Also try powering with the case open on a non-conductive surface if you need to observe behavior.

Remove the hard drive and back up data now if possible. If you see physical damage or the above steps fail, the most cost-effective routes are (1) board-level repair from a reputable shop to replace the damaged regulator/fuse/USB circuit, or (2) sourcing a tested donor motherboard/IO board. Take photos of any visible damage and get a diagnostic quote before spending on parts. Safety note: avoid powered probing unless experienced; laptop internals can still hold charge.
