I have been able to find replacement fuses at or. It's not something that you can find at your local Radio Shack store (I'd be quite surprised if they stock surface mount fuses).

Anything more than 1 ohm and the fuse is bad. With an multimeter in the lowest range ohms position and the motherboard un-powered, connect the meter leads across the ends of the fuse and you should read 0 ohms. It's the green looking rectangular "plate" marked "7X7", above and to the right of the black circle. Here's a picture of the main DC input fuse (look at the top for an "F2" designation the actual fuse is just to the left):Īlso visible in that last picture is a thermal fuse. As the fuses can be packaged in a couple of different styles, here's a picture of the two next to a T23 battery terminal: You then have to locate the fuse(s) and test them with an ohmmeter (resistance). You would have to disassemble the laptop to get at the motherboard. There should be one main fuse protecting the DC input jack and two at the main battery terminals. I would imagine that there are SEVERAL fuses on the motherboard, if it's anything like the T2x and 600 systems I've looked at. I will say that having a meter is useful for other purposes besides checking your AC adapter. The current draw is harder to measure since you would need to insert the current meter inline with the plug.īuying a multimeter (voltage, current, resistance) will probably cost you just the same as a new adapter, so it's your call. You should read slightly higher than 16V. The only way I know of safely checking the power supply would be to use a voltmeter and measure the voltage at the end of the plug. If you attach a known good adapter (see next point) and your battery does not charge, then something is up on the motherboard. Either the charging circuit or maybe just a fuse has blown. It is possible that something on the laptop motherboard has been damaged. So I don't think you are overloading the adapter, unless you have a bunch of other equipment plugged into your laptop. The 600E shipped with the same wattage adapter. The X40 appears to use the 54W AC adapter (IBM calls it 56W, but by the printed rating on the adapter, 16V 3.36A, my math says it's closer to 54W). do you thinkt hat might have fried my mother board? (maybe the charging circuit or soemthing?)Īnything else I can do? Thanks in advance for any insights. I'd used this A/C adapter tons of times in the past and never had a problem.

If it matters, I used the A/C adapter from my gf's 600e the previous evening.

Should I try to buy a new A/C adapter to see if it was the AC adapter that fried/ or is there another way? So my quesiton is where do I proceed from here? I don't have any warrantees since the Lenovo refurb warrantee is only 90 days. The laptop won't power up without the battery and it wont charge the battery when the battery is in place (The battery is still gets a few hours per charge, so i dont think its a battery problem). Now, when I plug it in, it doesn't seem as if the AC adapter is working.

Two days later, I heard a popping sound again and I unplugged it. There wasn't so I tried plugging in again. I unplugged it and looked around to see if there was water or damage anywhere. The other day, after I plugged in the laptop, I heard a soft popping sound coming from the A/C adapter brick. I have an X40 that I've had for about 1.5 years (purchased refurbished from IBM in Dec 05).
