    You would be better to replace the motherboard, instead. The BIOS chipset is an SMD. Surface Mount Device. It is soldered to the motherboard with a BGA surface mount. Have a BGA Rework Station handy? Scroll down, click on the Red - Take a few minutes to view the IR 650 demo video, and learn more about the BGA surface mount, Just for examples, a professional shop perform replacing with a BGA Rework Station? There are shops on the internet. (BIOS chip replacement) Wait until you see the prices, and include shipping and tax. Regards, joecoolvette

    Oh yeah, the question is where is the BIOS chipset on the motherboard; plus partial retraction of statement; I believe it to be on the Top of the motherboard, same as the CMOS battery. (RTC Battery In the photo look at the Bottom/Left. See the black square chipset with the silver smaller label on it? May not be it, but BIOS chipsets often have a silvery sticker on them. Not to sure that it is an AMI, or Award/Phoenix BIOS chipset. May be another BIOS manufacturer. At any rate the mounting to the motherboard follows SMD design, but Not Ball Grid Array mounting,

I have a Toshiba laptop model# C655-S5501 with a bad keyboard (Gator Aid!). I can't find an exact model # match through Amazon. Will the "Eathtek NEW Keyboard For TOSHIBA SATELLITE C655-S5128 C655

Check eBay. I've been working on computers for years and order ALL of my replacement keyboards through eBay. I just found 9 of them after entering your model number; about $16 with free shipping. Sarawill82 hit the nail on the head for the replacement; you tube is your friend if you're doing it yourself. If it doesn't have your exact laptop, look at other videos. It will give you an idea what you need to look for to replace the keyboard.

It beats paying a computer store a $45+ bench fee, and it will only take you about 15 minutes as a novice.

Don't try to clean it; you could cause more extensive damage than just replacing the keyboard.

How do I reinstall Bios

Need more details; the BIOS is a hardwired chip that is part of your motherboard. Rarely does it give problems. What exactly is your problem that you feel the cause is the BIOS?
Or..... do you mean that you want to flash your BIOS to upgrade it??

There is nothing you can do yourself. Send or take the laptop to a Toshiba Service Center to have the password erased. You may need to prove ownership of the machine, and to pay for the service.

It's designed by Toshiba but manufactured by HannStar the part number for the motherboard is DA0TZ2MB8X0 (where "X" is the revision code) you will need to disassemble your laptop to see which revision you need, it can be A,B,C...), so far i have seen up to revision "D"

Do toshiba satellites c655 have a built in mic?

The Toshiba Satellite C655 does not have a built in microphone, but it does have a mono microphone jack.
The following website has microphones that are compatible with the microphone jack.
You may verify at Toshiba's C655 website. It says "No Webcam and microphone built into LCD bezel".
Compared with the L670. It says "Webcam and microphone built into LCD bezel".
I hope this answers your question.

I have a toshiba satellite l305-s5933 laptop. I was installing drivers, because I needed to reinstall windows. I downloaded a bios update, and now its not working at all. Is there any way to restore the...

Yes, but you will have to either ask toshiba for a replacement Bios chip or search the internet for a Bios chip provider. Your problem is that the Bios has either not be allowed to finish installing or that the download update was corrupt. You will need to tell the vendor of a new chip the serial number of your motherboard, so have that on hand, to find the number you will probably have to lift the keyboard to see the number on the motherboard (See you handbook for how to do that). When you have your new chip you must carefully remove the old one and replace with the new one, avoid static and be careful. If you cannot do this then the best answer is to take your Toshiba to a dealer. Note: if a new chip is available it should not cost more than about €20 , so be careful of sharks!
