Question about Sony Computers & Internet

Open Question

My Sony Vaio AR18GP stopped working. The power supply went bang and, since then, the laptop doesn't power up or display any lights at all. Nothing. Totally dead. I took the case off and found that the power is definitely getting to the motherboard. Other than testing the 19.5v supply, I cant find anything else that would stop it working. Any ideas? Motherboard blown?

SOURCE: Loud bang, unit stopped working

I have seen the caps in the power supply vent, which means they get hot and the top pops up and splits open, resulting in the "bang" sound. If you have experience in electronics then remove the back of the set and examine the power supply, looking for any caps whose tops are bowed upward, and replace.

The best way to find the part you need is search around for the board manufactures name. Then goto there web site. You may be able to download technical data right off the manufactures web site. Over heating is a big problem with lap tops. You never want to place your laptop on a soft surface when its on. A soft surface blocks the fan from extracting heat from your laptop , resulting in a over heat and eventually failure. You want to place your lap top on a hard surface when its on. This will provide ample room for your fans to cool your lap top efficiently. You can also purchase a laptop docking plate. It not only is a hard surface but also it has its own fan to increase the cooling capability of your laptop.

SOURCE: Won't Charge

Common fix for this problem is a simple Power Management Unit (PMU) reset. This will basically re-sync the battery "brain" to the computer so they when when to charge and when to stop. To do this, simply turn your computer off, remove battery and power cord and hold the power button down for 7-15 seconds. Then you MUST wait 15 seconds after pressing the button before applying power or inserting battery. 75% chance this will fix your problem. If Not, Replace Adapter/Charger. They have a microchip in them that can go bad that senses when to send more current to charge battery. Apple motherboards are generally better built so I'm not suspecting that at this moment. Let me know what you find out.

OK either your hard dive has crashed or stopped working altogether.

When you hit f2 look for basic settings or something like that and see if
you can see your HDD listing. Then post again.

My sony vaio vgn-nw320f was totally dead.i had pulled up the battery cause it could not log off.please help me.....


Most sony laptop power supplies have a power LED that indicates if the device is A) plugged in {ok it happens!}, or B) fried and not providing power to the laptop. Check this first. If the power supply is plugged in and the LED is on (usually green or red) then see if you have ANY lights on the laptop itself. Its possible that your LCD display went bad but that the laptop is otherwise running. You may see a power, hard drive or wireless network light on if the laptop works but the LCD went bad. You can also connect an external monitor to the laptop and power it up to check the LCD.
I've also seen where the battery goes bad and it keeps the laptop from booting. Try removing the battery and power up (with the ac adapter plugged in) again.
If neither of these helps, you may be looking at some kind of internal short on the motherboard which is big money. Hopefully that isn't the case.
Hope this helps!!

Have you guys heard of any problems with the Sony VGN-CR507E


Well this sounds like to me that it has spontaneously failed, (No LED lights no anything" (sic) during that "Updating" If you have NO led's then in all probability, the PSU has faulted. Maybe it suffered a Power Spike? Or Power Outage? In any event, try troubleshooting the power supply.
