Inspiron 2600 refuses to power on
You may remember an earlier post by me in the BIOS forum, but replacing the BIOS chip did not help me in my predicament. Here's a rundown of what happened: suffered a bad flash, removed soldered BIOS chip on motherboard, installed PLCC socket, put in fresh BIOS chip, no power on. The fans, floppy, optical, and hard drives don't spin.
The laptop appears to be getting power, as the power and battery LEDs light up (the battery LED shows a yellowish color), but other than that there are no other signs of life. The second I plug the AC adapter in, the LEDs light up. With the battery, I have to press the power button to light them up.
I've tried removing all components and whatnot, but nothing has helped. So tell me, is the motherboard done for?

Hi,
I have had some problems posting this message, so here I go again.
I have the very same problem with a 2650.
I was able to detect a bad chip on my board (I hope the same is wrong with yours)
Just behind the power connector in the laptop, and under the main processor's power dissipator, there are a couple of little chips, 8 pins each and using the SOIC-8 layout, these chips have, in the case of the 2650, the number 4835 written on them. In my computer, one of them is damaged.
These chips are fabricated by Vishay Siliconix, and the complete refference number is Si4835DY (Which is discontinued, you should use Si4835BDY). These chips are very rare as far as I know and a little difficult to get.
You could try with an equivalent one, like the IRF7240 , produced by International Rectifier, that one is suposed to work well (As far as the vendor' datasheets say).
As you could assume, I am not responsible for any damage you could cause to your computer, I am only sharing my experience with you.
I hope this helps you.
Best Regards
