New Toshiba Whopee Factor -OR- Ghost of Secure Boot.


My Toshiba P55-A5200 laptop battery is dying. This is one of those internal batteries I have gotten two replacement batteries from Laptop Battery Express. With the first one somehow actually booted one time and nevermore, I ran it 4 5 hours before attempting to boot it again. With the second one the computer never booted. Putting back the weak old original battery promptly results in a boot when I turn it on.

With the old weak battery after turning the computer on, the Toshiba flash screen promptly appears and the boot is normal

My oddesy at killing secure boot to rid myself of windows 8 and install Linux Mint several months ago is chronocled at:
http://www.linuxquestions.org/questi...ux-4175545738/ I have been running Linux Mint flawlessly since then.

Since this is a no-boot problem I wonder if somehow the ghost of secure boot is hiding in the old battery (though I doubt it). Linux Mint is the only operating system on the computer. With the first replacement I turned the computer on with no external power and it booted off the battery but never again. It did not even do that with the second replacement battery. All that I get is the backlighted keyboard lights up and the hard drive spins. I checked the Bios and it is still on CSM and not UEFI so it has not apparantly reverted somehow.

When the old battery is installed the computer goes to the "Toshiba Flash Screen" and if you hit F2 really quick you go into the BIOS. With either replacement you do not even get to the Toshiba Flash screen. So should I expect something at the BIOS level is the problem?

In the BIOS security menu the settings are :
----------------------------------------------
BIOS Password
User [Registered]
Supervisor [Registered]

HDD/SDD Password Mode [Master+User]
Master [Registered]
User [Registered]

Boot Menu [Disabled]

BIOS User Password Permission [Enabled]
HDD/SDD Password Permission [Disabled]
--------------------------------------------------

At the top of theBIOS page it says "InsydeH20 Setup Utility"

I don't know if that helps but there is enough jargon that i am not sure what it all means.

The boot priority sequence was set to the
1 DVD
2 HDD
3 USB
4 internet (disabled)

I did swap the priorities of DVD and HDD but have not tried anything yet but I do not know what difference that would make with respect to this battery change.

For what it is worth I belive when the first battery replacement was made and did boot that one time, the AC power was not plugged in But after that no attempt with or without AC would work.

Any help would be appreciated The support page on line for Toshiba has all the utility of the mammaries of a porcine male !

No. my samsung rv510 now has a cheapo chinese big battery replacement and UEFI don't care.
It dualboots Windows 10 and Mint Mate 17 OK. I kept the old smaller battery as a backup.

But you never know. I always considered Toshiba gear to be voodoo child gear. Along with Hitachi newer laptops.

Edit: Are we talking cmos battery since you said internal. That makes a big difference as that is tied into bios.

I'd use a multimeter to check voltage on the cmos battery from "Laptop Battery Express"

If zero or below site specs. They gave you old stock that reached end of life on the shelf.

Main Battery

No not the CMOS batery we are talking the main lithium Ion 14.4 volt 43Watt Hour 2838 milliamp Hour battery that Toshiba decided to embed in the laptop rather than make it easily removable. Requires disassembly of the case to get at it and it is screwed down inside. @#%!@#%$%&#$.

PA5107U-1BRS part number. Costs $70 to $100 Not considered user serviceable by Toshiba I guess they want to keep their Techs employed. I have wasted hours and cash trying to replace this stupid thing What a PITA. First I had to spend hours seeking help to defeat the cursed secure boot. Now This ! The replacements are supposed to be authentic new Toshiba so unless they are counterfeit labelled they are real Toshiba Batteries.

The dealer has no idea why they do not work either.

Since the replacement batteries will not get the BIOS to put up the Toshiba flash screen I suspect a problem there somewhere but I don't have the slightest idea. If the bios has to find something on the battery that might have something to do with it. However I am wondering if Toshiba did something that only their techs know how to overcome. After all, they put microsoft's unethical secure boot to keep other operating systems off. Everything leads me to believe that Toshiba is not a good machine to buy. I got this one as a gift from someone who was exasperated with Windows 8 It runs Linux Mind just fine but the original battery seems to be dying.

If the computer has to have the BIOS in UEFI mode to initialize a new battery the problem will be complicated by the fact that there is no remnant of windows on the machine so can linux use the machine with a UEFI bios setting?

Beats me? Like I said. My Samsung and Dell and Compaq laptops take a battery change with no sweat involved. All newer gear with UEFI bios. Compaq and Samsung still has a Windows partition.
The Dells do not.

1st I have heard of removing the laptop case to access the battery also.
Hopefully someone with this model of Toshiba will chime in. I'll try some google fu anyways.

In case you missed this

A link to a manual <not sure if it is worth it. Help Owl site can be a PITA>

https://www.manualowl.com/p/Toshiba/.../Manual/197958

Sorry. That is all I can find tonight.

I got a new lenovo y70 a few months ago and you also have to open the case to replace the main battery.

FYI, Microsoft didn't create secure boot.

Could it be in the BIOS

Since reading the BIOS screens may have a lot of details I went into the BIOS and photographed the screens so you can see what I see. There are two screens I deemed more relavent than the others.

First is the BIOS Security Screen.
I figure that some security setting that i do not understand could be a source of interference in getting the computer to accept the new battery.

Second is the BIOS EXIT SCREEN
This one is more ominous or at least seems to me to be so.
This BIOS option is titled: Disable Built-In Battery, and Power
It is current status is: Off
The Item Specific Help says:
Quote:
Temporarily disable the battery for servicing the system.
After selecting this item, the system will be automatically powered off,
then ready to be serviced.
This operation is performed when the AC-adaptor is attached.
My problem with this is that This disables the battery and that seems to be the status of the new batteries I am installing. However there is nothing here to tell me how I am going to be able to re-enable the battery once the servicing is done. And with the new batteries I cannot even get back into the BIOS because I am not even getting the Toshiba flash screen where I can quickly press the F2 key to get the BIOS setup.

Obviously the last thing I need to do right now is disable the old weak battery which is the only way I can currently boot anything, unless I know how to re-enable the battery. I am not very trusting about what the writer of the Item Specific Help meant when he/she wrote "Temporarily Disable". Just how temporary is temporary? And how do I reverse it if that is a manual activity?

If I am lucky, someone with experience with such a BIOS option here may be able to tell me if this BIOS option has any relevance to my dilemma, and how it works.
It is not even clear to me why one would have to shut down the battery in the first place as it can be changed without doing that but perhaps there is some advantage. Externally removable batteries seem to have no such need however so I have no idea why such an option exists.

Don't worry about it.
That is the default setting. Leave it alone.

Look at the bottom of page 42 on the Lenovo User Guide and you will see a similar statement/warning:

http://www.lenovo.com/shop/americas/...elix_ug_en.pdf


Note: The ac power adapter must be disconnected from the system to perform this operation.

Quote:

The battery will be automatically re-enabled when the ac power adapter is reconnected.

Maybe someone else can chime in regarding your other points.
