I think either I or Vanguard must be mistaken. He seems to be implying
that you were about to crunch the entire laptop with a sledge hammer,
whereas I think your other half meant just the hard drive, assuming it was
dead, did she not? This is a standard way of preventing personal data
being retrieved from binned HDs. Personally, I use a lump hammer and a
cold chisel on a concrete floor or step.

Yes, that's what she meant. Destroy the HD.


But is the HD really dead, or has it just got corrupted ...

It's not dead as it brought up technical screens when tapping F8 or F2. It
ran fine with the battery not charged and plugged in.



On the back it just says Satellite followed by numbers. I don't know
which
numbers would be relevant. This is the 1st number. C655D (or 0) S5063
system
unit.

I would suggest going to Toshiba's site and comparing what you have with
pictures of other models and their given designations one of which will
probably be close to the above. When dealing with problems or buying
spares, it is *nearly always important* to know exactly what it is that
you have.

This was given to us by a realtive. She said it was too slow and wanted a
better faster newer laptop.


What makes you think it's the battery since it worked fine without it as
long as it was plugged in? I had this same "going blank" with the
blinking
"-" in the upper left hand corner before and they were desktops. I don't
remember the exact figures anymore but to fix them, according to the
shops
where I lived at the time, wasn't worth what it would cost. An XP and a
Vista both went the same way.

Shops may be right in that it may not be commercially viable for them to
make certain types of repairs, or for you to pay them to do so, but
probably they also hope that they can persuade you to buy a replacement
from their stock, while some repairs, a new battery is a good example, you
can do yourself economically.

This is true. They knew I would not buy from a small shop. I bought all our
past computers from CompUSA before they went under. One from Best Buy and
one from WalMart. I could usually get rid of problems like this by accessing
safe mode and doing as System Recovery or Restore. But nothing led to safe
mode.


It wasn't dead when plugged in as info came up when I tapped F2 or F8 but
not safe mode. Nothing that showed was familiar to me. A repair tech
would
know what the info meant but it was Chinese to me. So it didn't need a
battery to run. I hate to toss it because it's like new. No one liked it
because it was slow. I was hoping to do a system recovery but couldn't
get
into safe mode. I don't know any other way to do a system restore or
recovery.

Most PCs can do some primitive diagnostics from the BIOS. The BIOS is
usually entered by pressing or holding down a particular key at a
particular stage in the boot process - favourites are Del, and either
F10 or one of the other function keys across the top of the keyboard.
Again, going on to Toshiba's site and identifying the model number may
help you find out which key is the magic one. Some laptops, such as
Dells, can even perform full diagnostic tests by pressing a different
magic key, IIRC F11, but my memory for such intermittently used
information is getting a little dodgy these days, and anyway you have a
Toshiba, not a Dell, so it's likely to be a different key, if full
diagnostics are available at all.

I'll do some Googling again and see if I find anything helpful. I'm sure a
tech would have found those screens that came up helpful. To me they may as
well have been in Chinese.


You may find this page on my site, useful - although when written I
mostly had desktops in mind, since writing it I've repaired some laptops
as well, and while the details may be different, the principles are
exactly the same:
http://www.macfh.co.uk/JavaJive/PCHa...areFaults.html

In particular, either ...

If the laptop can boot from a USB stick, then download an Ubuntu or other
Linux distro - make sure you get a suitable one, 32-bit or 64-bit as
appropriate - install it on a 2GB or larger USB stick, depending on the
size of the download, and see what messages Linux generates as it tries to
boot the PC. This may give you some useful pointers to a hardware fault.
If the PC boots from the stick, then you should see your hard disk
partition(s) as clickable icons down the left hand side menu (in Ubuntu,
other distros may be different, for example the icons may be on the
desktop). Try this and come back to us with a description of what
happens, particularly whether the PC boots at all, whether Linux lets see
your HD at all, and even the contents of it.

OK.. will do.



.. you can mount the HD in a desktop, do that and diagnose it from
there. If, as is likely with an old laptop, you have an IDE drive, you
would need a 2.5"-to-3.5" HD connector/convertor and attach the other side
of that to a spare IDE connector and power cable, whereas a SATA drive can
be attached directly to a standard SATA cable, but you may need a
convertor for the power cable - it all depends on the particular
combination of laptop HD and desktop motherboard and power supply cables.
Try this and do a chkdsk on the laptop's HD - you will probably have to
go into Disk Manager and give the laptop HD a drive letter first.

I wouldn't know where to start and if I want to devote the time it took to
do it. I've had almost no experience with the inside hardware of
computers. The HD doesn't look like anything I've seen in a DT PC. Just
getting to the wires to get the DT PC to come forward is a major
production... seriously. BTW, the HD is a Seagate 250 GBs - the other info
is all in Chinese characters.


Either way, you should be able to find out if the HD can be retrieved by
repartitioning and reinstalling, and the first should also suggest whether
and how much of the rest of the PC is functioning correctly.

What I meant was what we need the information that OP refers to but
doesn't quote/specify. I'm still not sure whether the machine boots on
external power with or without the battery. See Vanguard's post, which is
an attempt to get clarity on that question.


Let me clarify. I noticed the battery stopped charging maybe 3 weeks ago.
The battery looked to be at zero for days. If the cursor was placed on the
battery icon it read something like, "plugged in not charging". I figured
the battery bit the dust but it worked fine so anyone who wanted to use it
would plug it in, then turn it on. It would boot right up into windows and
run fine. Then one everning I did the same but the screen was black with
the blinking " - " in the upper left hand corner. I shut it off and started
it tapping the F8 key and some window came up with tech info but no choices
such as safe mode. One window came up and the choice was to do a memory
check which said memory was OK. I'm not sure which F key brought up that
window.

That's as far as I got with it. You know the rest.

Doesn't the laptop's own boot screen offer a choice to hit a special key

The choices a

HDD/SD

It says "Select the priority for booting the computer."

So which one do I select? I don't have a CD or DVD for this laptop. None was

https://support.toshiba.com/support/...tentId=2737864

A special-use partition is created on the HDD to perform the factory
default installation. It is either an image to lay back on the HDD or
an installer to perform a default install. If the laptop didn't come
with recovery CDs, the manual probably mentioned how to create them
after you received the prebuilt computer.

You went into the BIOS config screens. Looks like the laptop is
working. The problem is with Windows or the hard disk where it is
installed. Could be Windows is fouled. Could be you have a bad hard
drive. Insert the Windows install (or any other bootable disc) into the
CD drive, reboot, and select to boot from the CD drive. Does that work?

If saving what is on the hard disk is not critical (i.e., you're willing
to start fresh), boot the laptop and use its recovery option to restore
the laptop back to its factory-time state. See:

https://support.toshiba.com/sscontent?docId=98082971

You are already past the POST screen and the BIOS is asking which device
you want to boot from. Windows is on the HDD. The list is the boot
order for the device types.

Step 4 is where you decide whether or not to perform a recovery (to lay
a factory image onto the hard drive).

You move around the menus with the arrow keys. To change the value of
the parameter that is currently highlighted, you use F5/F6. F9 puts all
such values back to their default (_usually_ this means a set of values
which may not give the best performance the machine can achieve, but
which are likely to work in most circumstances; its main function is for
when the user thinks "I've changed something and the computer is now not
working/behaving erratically, but I can't remember what I've changed").

Doesn't the laptop's own boot screen offer a choice to hit a special key
or key combo the restore the computer to factory-time setup?

I think the hard drive would have to be working - and able to boot - to
get to that option. Not necessarily, but usually.

At the very top it says, "InsydeH20 Setup Utility."

The Boot tab is mostly techie speak so I have no idea what to do with this.

HDD/SD
FDD
CD/DVD

It says "Select the priority for booting the computer."

By fiddling with the keys, you can usually change the order of that list
(there might be a "move up/move down" key pair); it determines where the
computer looks for something bootable. The only ones you're likely to be
able to use are HDD, CD, and USB.

So which one do I select? I don't have a CD or DVD for this laptop. None was
given to me with the computer.

I presume it does have a CD _drive_ though.

b) BIOS can't access the HDD. There are several possible reasons for
this. The worst case from your POV is that the HDD is toast. In that
case, rescuing the laptop would entail opening up the laptop and
replacing the HDD, not a simple job.

A more favourable (cheaper) possibility is that the HDD connector is
bad, and reseating it would fix the problem. Like changing the drive
itself, that would entail opening up the laptop.

Not necessarily: it depends whether the laptop has an HD hatch. A lot
do, i. e. a panel which can be removed (sometimes needing a _few_ screws
to be removed, granted) to access the HD, but not requiring the whole
back to be taken off, which I agree is decidedly fiddly. (On this laptop
- also a Toshiba - one of the screws for the HD flap is actually under
the RAM flap, but if this is the case it should be fairly obvious.)

You may be able to find out if BIOS can access the HDD. One of the
Diagnostic screen should include s a test of the HDD. Look for anything
that looks like it will test or scan the HDD, and run that. If that
test or scan fails, BIOS cannot access the HDD.

Though I think BIOS functions to _test_ the HD are rare.

I don't have a CD or DVD for this laptop. None was
given to me with the computer.

You may be able to download-and-burn, or borrow, one that will get as
far as the repair console. Only of use if the HD is working OK and just
files have been corrupted, though.
[]
You could run a Linux from the CD/DVD drive, which would IMO would
merely confirm that the HDD is bad.

So, based on what you've described, IMO the HDD is the problem and you
have to decide whether it's worth your money to have the laptop
repaired.

Best wishes,

I'd say there's still a strong chance that it's just file corruption
(or, if you're _very_ lucky, the HD has just come disconnected, by
sliding around in its slot).

blinker in the upper left hand corner, I feel it's most likely the death of
that PC.

There are too many. 6 tabs on one screen. Text on each tab. None mention
Safe Mode or system recovery. Example. On the Avanced tab it says: Boot
Speed. Boot sound. USB Legacy Emulation. System Configuration.

InsydeH20 is a *BIOS* company.

Pressing F2 or F8 or F12 early after the power
comes on, caused you to drop into the BIOS.

After the flashing "_" appears in the upper left
hand corner of an otherwise black screen, is the
OS booting. At that point, some of the older OSes
would accept pressing of F8 to enter the
Safe Mode OS menu.

The timing of the key press is critical. On
a machine with a BIOS which happens to use F8, you
will end up in the BIOS if your timing is not
perfect. And if you're late during the OS boot
phase, the OS will (attempt) to boot in regular mode.

On the modern OSes, you can use BCDEdit from the
OS installer DVD or from the emergency boot CD,
use the Command Prompt window there, to set a BCD
option to cause the machine to stop at the
Safe Mode screen.

However, if the booting bits of your OS are
corrupted, it might never even get a chance
to consider your presses of F8, or your
entreaty via the BCD, to stop at the
Safe Mode screen.

*******

As an example:

1) Boot the computer using the Windows 7 SP1 installer DVD.
Select the troubleshooting options, rather than anything
related to installation. That might require accepting the
"language" screen when it comes up, but after that, there
should be a button for Troubleshooting. This gives a
Command Prompt window.

2) Look at Option 3 here.

https://www.sevenforums.com/tutorial...safe-mode.html

bcdedit # review the details
# sometimes a refusal to boot is
# caused by a blank entry for a volume

bcdedit /set {current} safeboot minimal # Add the entry to BCD

bcdedit # Verify it looks correct

3) Type "exit" in Command Prompt or close the window,
then allow the machine to boot to the hard drive.

I don't know why you're heading to Safe Mode, what you have
in mind, but that's an example of doing it.

To remove it later, you can repeat the above approach from
a Windows Administrator (elevated) Command Prompt window.

bcdedit # review the details
# Make sure the menu item is in "Current"

bcdedit /deletevalue {current} safeboot

Some of the BCD options can also be neutered by "/set"
to a benign value, and then you don't even need to
deletevalue to switch them off. BCD also has
options where it has Booleans, and True and False
are synonyms for Yes and No.

The nice thing about BCDEdit, is a hell of a lot of
nice examples have been written and documented since
Vista came out. And working with the BCD (from an
emergency boot CD or from an installer DVD), no longer
has to be "mysterious". The sevenforums site has
recipes. Not all the recipes are "most useful",
and the reason I selected the Option 3 from the
above one, is a lot of what we do here is "emergency"
edits, where the user can no longer use the regular
OS to edit stuff.

You can do offline edits (edit the BCD on other drives
in the computer), using the /store option.

bcdedit /store C:\boot\BCD /set {bootmgr} displaybootmenu True

When you do stuff like that, it's up to you to use
the "dir" command to actually verify the drive lettering,
since drives get different lettering in virtually every
environment you work in.

That particular command there, happens to be a favorite of
mine, because it adds a "WinXP style black boot menu" to
OSes like Windows 10 :-) Just ignoring the two OS boot
choices here, there *is* a row on the screen that says
to "press F8", so this menu just happens to give you
access to all the Safe Mode options. I want this window
for the "press F8" option, not because the OS boot
choices look pretty or something. This is how I get to
Safe Mode. The black screen sits there for 30 seconds,
giving plenty of time to make a single press of F8.
