laptop won't POST. I need to reset the bios but..

March 26, 2012 at 00:10:38
Specs: Windows 7
The laptop won't POST at all. I know it's not a screen or graphics card issue. So I went to reset the bios by opening up the laptop to find the CMOS battery. The problem is that the CMOS battery is soldered onto the motherboard and I can't find any pins as an alternative.

I've tried googling the manual for this laptop but I could never find a manual with the hardware aspect regarding the laptop. The laptop is a Toshiba Satellite L505D-GS6000, with windows 7 home on it.

If anybody has any ideas I am more than willing to try them out.

Thanks.

just take a screw driver and short out the two leads of the BIOS battery where they are soldered to the motherboard. This will clear your BIOS. On a side note, I have seen the AMD processors fail, a lot. So you may want to try a test processor, just make sure that the year on the processor that you test with is the same as the original.

Thanks.. but can you be more specific as how to short the two leads? Would I take the screw driver and connect the metal tip with the two leads at the same time?

Hi Civoskela,

I do not think shorting out the battery itself is a good idea.

Also resetting the bios unless it is absolutely necessary.

It would help if you advised exactly what (if anything) is displayed when you attempt to post.

Have you tried booting from a bootable cd?

Good Luck - Keep us posted.

Why would you suspect a BIOS issue? Did you enter the BIOS, mess with the settings & screw something up? If not, I highly doubt the BIOS is the problem.

My thoughts exactly, if you did not mess with the settings then it is probably not the problem. Start over and explain the problem and all that you have tried and you probably will have many suggestions to try that will make more sense.

You have to be a little bit crazy to keep you from going insane.

The computer doesn't post at all. When I try to turn on the computer there is only a black screen with no beep codes. I'm suspecting it's the bios because I've run out of options. The problem started after I ran an update for superantispyware and had to restart (the computer has issues with malware).

A hard drive infection cannot have an effect on the post, but a bad hard drive might. Unplug the hard drive and see if it posts and lets you into the BIOS set up. If you also remove the memory you should then get the memory beep tone if the board is equipped with the motherboard speaker. Since it is a laptop, try all with different combinations: battery only, battery and AC power, and AC power and no battery, since a bad battery can cause non posting if shorted internally.

Yes that is how you reset the bios on that board, you short out both the leads and the voltage and the amperage will drop to 0 so it will clear your CMOS and it will not hurt your battery or your mainboard. I have done it numerous times. I don't think your having a problem with your BIOS but like you said it's worth a try. I would try a test processor, if not start checking the capacitors on the board.

So I tried to remove the RAM sticks, hard drive, cd drive, and still nothing. When I remove both RAM sticks out I don't get any beep codes.. It's always just a black screen and the laptop does nothing.

I'll probably try my luck with resetting the BIOS. For shorting the leads, how long would I leave the metal tip of the screw driver there for?

You can short out the leads for about 5 seconds or so, that should do it. Don't think it will fix it, but worth a try.

Sounds like your logic board has no logic :)

When I short do I need to have the laptop powered on in any way? I tried just putting something metal in between the 2 leads, and still nothing. What other options do I have?

Does your Toshiba has a nVidia chip? you may need to apply head to the video chip and 90% of the time that will fix it. There is an issue with the nVidia and the ATI chips, but you will have to google it to get more information on that. Just look in youtube for Reflowing nVidia or Video chips and you'll know what Im talking about.

The laptop has an ATI chip and is not know to need a reflow. It has, bois boot locks, corrupted bois, bad capacitors and mostly failed bad processors. If anything you can try a bios recovery with a crisis disk

I have exactly the same problem and am just about to give up and go and buy a non-Toshiba. I think it's a motherboard component that's reached the end of its useful life - we are not the only ones with this problem.
