I'm still in the process of identifying the model of my machine, but believe it's a Pavilion G6 about 1.5 years old. I really need to find my receipt. I bought it at Staples if that means anything and it was running Win 8. Anyway, my son had the laptop at college, and accidently plugged his roomates Bose speaker power block into the machine I'm referencing and was not able to power it or charge the battery. I'm an ex-Bell labs HW engineer, so here's the deal as far as I can report it:
1. Bose supply...18V DC output, 1.1 Amp, REVERSE POLARITY on output...Prob enough said.
2. No lights on machine when battery (had another charged battery), of correct HP power block plugged in (no surprise).
3. Pulled motherbord and have not identified fuse or protection diode which I may be able to replace if they even exist.
4. Came across this forum, and am confident the info I may be able to get could be presented here.
From Motherboard, here is the info I was able to capture:
Model RS3
HP tag with barcode: 683029-501
I know this barcode may represent a sub assembly or other component, but it was pasted to the motherboard.
Appreciate all input regarding this matter. Thanks!

Evenning Gents, I suspect that the fuse on my ASUS ROG laptop might have blown up. Netflix, chill and wine wasn't the best idea and some wine have landed on the keyboard. Laptop worked fine untill I switched it off and couldn't power it on back again. Power on is made thorough keyboard press which is connected to main cct though ribbon cable. Below is the image of the rig and I would be very thankful if you could advise me where I could find the fuse on it. Images: 1. Main DC power input (top right corner, just below the screen supporting bracket) 2. Main battery, connected through small 8 pin connector, red and black wires. Keyboard ribbon cable, in the middle, the green ribbon connected to white 32 pin connector. 3. Big picture of the board

Hi tom911 Signed up just to answer here... Laptops these days hardly use fuses anymore.... If you are lucky they use a 0 resistor in some cases. (SMD type). You generally only get fuses on the LCD/LED connection and the VGA/HDMI connection ports, sometimes the LAN ports as-well. I only find fuses on high end laptops they seem to actually care about the components. Anyways since you mentioned a spill. I would suggest taking out the motherboard from the case. be patient and avoid build up static, discharge yourself to some tool hooked to earth and use a anti-static mat or a wood board over all avoid touching circuit components but also don't over think it. With the board out make sure there are no build up / corrosion spots on the top side (under the keyboard side). Also you said it was working fine which could mean that the spill weren't that much and only damaged the keyboard since the power button is on the Keyboard. (I hate these...)
So thing is if you can give me your model/detail number on the mother board, its usually printed in white and usually inside a printed block. See image here as sample:
So yeah good luck.

One of my Toshiba laptops has two. I haven;t taken it apart yet, but I did order them. Look around the battery area and the power input. Look also for a designation that begins with F. e.g. F1, F2
