Sir, I have a dell vostro 1550 model laptop, it is completely dead, only 19 volt comes, no indicator is turned on, can there be a problem?
Is it posting, or doesn’t it show anything? It does sound like a voltage issues, I would up it to a higher level and see if it boots then. Also check out other methods, firstly try with a new cable and see if it helps.
Have you tried it with the battery disconnected and just the power supply/charger plugged in? See manual: vostro-1550servicemanual.pdf page 11. Does that fix it? Then just defective battery. No? Then try resetting the BIOS by taking out the coin-cell battery, page 33 in manual, and then press the power button to discharge any power in computer. Should be 3 volts. Replace if lower. Let us know how it goes.
