Vgn-ns38e do not power on - no power led - cmos varta 0.1V - laptop batt discharged

another method I have used that works is to remove CMOS batt as you have done before - do not replace it yet though.Power on the dv7 without the battery in then off by holding down the button until it switches off.Remove AC power hold down power button 5 secs to dissipate power and replace CMOS batt,plug in AC and test.Hopefully it clears the bios settings for you

Here is a complete guide to disassembly of the VGN-SZ laptop.

The trick here is to get to the CMOS/BIOS (referred in the manual as the 'reserve') battery. Remove this battery and leave the unit with no battery, A/C power or CMOS battery for an hour or so. Then replace the CMOS battery and reassemble. Power it up. Its going to 'yell' a lot since the BIOS was flushed and all information will have to be put back in. However after you do this, you should be all set.
Hope this helps!

u will hve to take out the cmos batt.from the down bord assembly and restart it with fan working .
miro cell is inserted into it's bay

After a quick read-through of the user manual for the P505-S8950, the only way to discharge the CMOS memory seems to be removal of main battery and power cord for and extended period of time in order to cause the CMOS battery to discharge.
There may be a way to open the laptop and remove the CMOS battery to speed-up this process; however, my previous experience with taking apart a Toshiba laptop led me to the realization that they are not designed to be easily disassembled -- I had a heck of a time reconnecting the display data cable (I had to use a chopstick and have a lot of luck to get it back together).
I would suggest opening each of the access doors on the bottom of the computer in order to determine whether or not you can get at the CMOS battery that way; otherwise, I think your stuck with waiting a LONG time for the CMOS battery to discharge or VERY carefully disassembling the laptop.

in order to reset the bios password you will need to remove the cmos battery and leave it out for about 15 minutes. This allows the stored up charge in the capacitors to dissapate, and after they discharge is should be reset back to original factory bios setting.
once into your bios, make any changes needed for specific hardware before you reboot computer and go into diagnostic testing mode.

it sounds like the cmos batt had the same problem with my desk top once changed cmos batt all was fine .the batt is located on the under side of the laptop you will see some removeable panels just check under these,but be carefull the batt might be soldered in, some are some are not. if soldered in you might want to get a professional to change it as the heat could damage your computer.
hope this helps.

Hello,
There are 2 ways you can reset your bios.

1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete

2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete


This is a great troubleshooting step for those of you having POST issues or no POSTing at all. Like other troubleshooting steps, this will not always work but usually will depending on the problem.
Please let me know if you have any further questions or concerns.
Thanks.

hi
u carry out your laptop battery and then restart and if you find still problem, and want technician help contact http://tinyurl.com/msfzw7

Hi Odek, You have to short the CMOS reset pins on the motherboard. You can find the location of these 2 or 3 pins on the motherboard manual. For Enisco's problem the monitor power cable is not properly earthed. You can either earthed it by connecting a wire from any conductive part of the monitor to a earth pin on the wall plug or something conductive near the monitor like a will sill. I would probable change the wall plug or the faulty power board. regards

I have found that sometime these Rodents seem to have a "Taste" for a certain "Type" of AA or AAA cell, one needs to get the Highest Discharge rate one can get. Often the "Brand" of Batts supplied are the "Only" ones that seem to work 100% alla time? I have had similar problems with customers B4, and I find the Varta series of battery to be great. & remember just because you bought them "New" don't mean the Batts are always "Fresh", get batts from a place that has a high turnover.
