should produce reasonable quality sound when we are listening to the bbc
iplayer, dvds etc..
I have a laptop at present but the sound quality is tinny and abysmle..
The Acer laptops are shown as having dolby sound but I am not sure if this
makes a difference. it is not easy to try them out in a store otherwise I
would take along a cd and listen to that.
Does anyone know of a brand that has reasonable sound output?
My price range is between �450 and �550.
Thank you.

Have you tried using media players other than the default player that
came on your laptop? Some players sound better than others. Try them
to see if they will improve on the sound. Also try adjusting the
equalizer which often comes set to 'flat'. For example adding a little
bass may help with the tinny sound.

My Acer 5516 15" laptop has audio comparable to the mp3 players I own
except for one annoying thing. It has weak electronic sounds in the
background. Clicks and buzzes including drive noises. They can only be
heard on earphones and cannot be heard during songs or other audio
played at a normal volume. But it is still slightly annoying. Course
this is a US$339 laptop so I got what I paid for. Fortunately other
than reviewing downloads prior to transfer to my portable players I
don't use the audio much so it wasn't a deal breaker.

If audio is very important to you I would think that trying the laptop
in the store is about the only way to be sure you get what you like.
>Does anyone know of a brand that has reasonable sound output?
You will surely get suggestions. However will you gamble big bux on
what someone else thinks is good sound? I wouldn't... ;)

any laptops. The differences are in the output stages and the speakers.
The best advice might be to use external amps and speakers, but some
laptops are definitely better in this regard than others.

After you're as dissatisfied as the rest of us, start shopping for an

Here, waste $11.82 on these Sennheisers:

I don't think you'll find ANY laptop that sounds good, even ones costing
more because BOSE sold 'em a license to use their name. "Poor" is my best

putting earbud drivers in little plastic tubes and calling them a
"speaker".
Good luck.

"Newer Toshiba laptops will see (or rather, hear) the wonders of Waves'
MaxxAudio signal processing technology. Unfortunately, this improvement
can only be heard on Japan-bound notebooks."
I also thought my old Toshiba 2595XDVD laptops from '99 sounded very
well for being a laptop. The speakers were very large and were on top of
the top keyboard row.

*** The likelihood today of getting decent sound in anything in that
price range is low. They make them as cheaply as possible. If you want to
get a pro model, they might sound better but will cost you considerably
more.
I think the suggestions here regarding external speakers may end up
being your best solution as far as sound goes, but would reduce
portability, and would extend the set-up time. )-:

The differences are not components or specifications, but rather what I

pressure to cut down on cost, weight and size, all of which contribute
to systems that are electrically well designed but which are

I don't know... as computers are always going to get more powerful and
less expensive over time. And I am not convinced that there is a decline
in built quality either. As laptops have also improved over the years
too. Like getting rid of florescent lamps and inverters and trading them
for a row of bright LEDs. Which are much more reliable and not as
sensitive to shock.
Speaking about not sensitive to shock, we are only a few years away from
SSDs replacing old mechanical hard drives. I too also believe this is
far better than the older method. And speaking of mechanical hard
drives, these too have been improved over the years. Some even sport
anti-shock features. They have also increased in capacity and also
dropped in price.
Take my old Epson PX-8 built back in 1984. I like to think of it as the
first netbook. As it is about the same size and shape. But the display
is terrible and it is heavy. Besides it is very limited compared to
today's standards. Although it is well built, nonetheless. Although it
also cost $2000 (including the RAMDrive and extras) back then. I do love
the Epson's keyboard, but for that price you should get a great
keyboard. Even then and now though, I would have traded it for one of
today's netbooks in a heartbeat. ;-)

If you have been taking apart a variety of models made over a 15-year
period, your doubts about that would disappear very quickly. They don't
build them like they used to. It's only partly cost related, the
pressure to make things smaller and lighter (and, especially, thinner)
also contributes. The circuitry, the ICs and other components, are not
the problem. It's the overall mechanical assembly, everything from the
thickness of the motherboard and the thickness of the foil traces to the
all-plastic (thin, cheap plastic) cases. The build quality is not what
it used to be. Again, the problem is not the components (which includes
the hard drives), it's how those components are assembled.

Well I have been taking them apart for the past 15 years. And yes, I
have seen what you are talking about. Although not everything has gone
that way. For example, Asus President didn't want the EeePCs to have
that cheap feeling. So they made sure it had great solid lid hinges. And
that was a weak point of laptops even some 15 years ago.
Another trick Asus did to save on weight was to use the keyboard as a
heatsink. As why add a heatsink when the keyboard would work too? I
believe this was another great idea. Although the PCB are indeed very
thin.

Well I know what you both are saying. But not everything was too rosy
back then either. As what about the old Toshiba 1950CS 486 laptops built
in '94? Toshiba didn't have fans in them yet and in a few years the
power regulators cooked themselves to death.
Or what about my Toshiba 2595XDVD laptops ('99 era)? Both of them would
just suddenly freeze up about twice a week. I would lose all of my
unsaved work. That was really annoying as I killed power and rebooted.
Even Linux users complained about it. So it wasn't Windows. Years later
I discovered all one has to do to unlock the computer was to hit the

mostly on Toshiba (followed by Dell, Gateway and Lenovo).
Actually, I had more problems with AC adapter sockets on motherboards
themselves back in the old ("Toshiba built") days. That is the one --
the ONLY -- area where I think things got better (almost all later
Toshibas mount the DC input jack on the case rather than the motherboard
and have a short cable to the motherboard). The sockets still fail,
which is a user error (mechanical stress), but now you can replace the
socket without having to replace the motherboard (or remove and replace
a component soldered to the motherboard).
However, I've seen a HUGE number of motherboard failures in Toshiba
units that I didn't used to see. Apparently (because I don't do this
work myself, but I talk to the people I send motherboards out to) the
motherboards themselves are now so thin and flexible that the BGA
soldering of the chipsets to the motherboard fails. And I see a LOT
more problems with Toshiba units in this regard than with some other
brands (the A105 and A135 were particularly bad ... a huge number of
motherboard failures).
Another big issue -- and one that is pushing me away from Toshiba,
frankly -- is problems caused by overheating. The same guys who replace
BGA chipsets on motherboards tell me that occasionally they can just
"reflow" the chipset and it fixes the BGA connections. BUT, too often,
the chipset itself is fried by overheating. The chipsets have heatsinks
also, in most modern laptops. But when the cooling system fails (e.g.
the fan and heatsink become clogged with dirt, dust and hair), the CPUs
handle it relatively gracefully (they "throttle" themselves and prevent
their own destruction) but the chipsets don't handle it so well and are
often destroyed. Not a huge difference between Toshiba and other brands
in that regard, EXCEPT .... Dell and Lenovo and even Gateway provide a
door (removeable panel) on the bottom of the laptop explicitly for
cleaning the CPU cooling system (heatsink and fan). Toshiba used to do
that in some older models (the A40's, for example), but in the newer
units (again, starting, it seems, with the A100/105 series) they don't.
THERE IS NO WAY TO CLEAN THE CPU HEATSINK AND FAN, other than a total
disassembly of the unit (remove the motherboard from the case, because
the CPU is now on the bottom of the motherboard in most units). Of
course, this never happens, and we have, again, a huge number of
motherboard failures. [When I do disassemble a unit, it's not unusual
to find a couple of CUBIC INCHES of "hairball", often so bad that the
fan blades no longer are even capable of turning.]
What's sad is that this stuff is just plain dumb. There is no reason
for it, it doesn't really save anything, but "that's the way they are".
For no apparent reason.

The dimensions that you refer to for the motherboard are a function of the
frequency of the signals that the traces are required to convey. As the
various clock speeds rise, the traces have to become narrower to minimise
the series inductance. At the same time the traces have to be closer to the
ground plane to allow the signals to propagate with the minimum of
reflections. This points to thinner motherboards with narrower traces. I
agree with you about the plastic mouldings though. Breakage is all too
common, but worse is the tendency for the lid to crack around the hinges
precisely because there is unsufficient meat to withstand the flexing as the
lid is opened and closed.

I have been purchasing laptops since '84. And all except one are doing
just fine (except for the original batteries). So while I believe there
are some makes and models which doesn't last, there are many makes and
models that just keeps on going and shows no signs of ever dying.
It isn't the after warranty failure that seems to get me. But rather it
is the advancing technology which makes them obsolete to me. So I
continue to purchase newer and newer models. I usually get 3 to 6 years
out of a machine before I replace it with newer technology.
It was the 90's which seems to have turned out the most unreliable
hardware IMHO. Some of those in the 80's wasn't too hot either. The
modern day hardware I have, I still see lasting over 25 years from now.
Although I don't think I'll still be using them for everyday use for
that long. But heck, you never know. As I am not that impressed with
Vista and Windows 7. And I probably won't be with Windows 8 and 9
either. ;-)

usual 1 year warranty period"
Having worked for multiple PC mfgrs., I can tell you that manufacturers
do not think that way. It does not make for repeat customers; sure, it
gets the customer to buy a new PC, but if yours failed "too soon", it's
more likely to be replaced with another brand (and it also makes for bad
reliability reviews in "consumers reports" and other publications and
surveys).
The nice thing about PCs, from a manufacturers perspective, is that they
are self-obsoleting, even without actual failure. A 3 year old PC is
obsolete, even if it still works perfectly. Add to that the OS upgrade
cycle (most people will not upgrade a PC from Windows X to Windows X+1,
they will replace the PC). And, finally, a very real reality is that
most people will even replace a PC rather than just reinstall Windows.
All it takes is a bad or corrupted hard drive, a bad virus/malware
infection or even just the routine "registry bloat" in a PC more than 2
to 3 years old, and you have a customer in the market for a replacement
laptop. However, if the previous one had poor hardware reliability ...
the replacement is more likely to be another brand.
As for older PCs, however, I make a small part-time business out of
refurbing and selling 1410/15 and 2410/15 laptops. They are still very
usable, and I get $175 - $225 for them, on E-Bay and sometimes locally.

Not actually the case. Larger conductors means greater series inductance
and that in turn means limits on the propagation of higher frequencies.
This is why higher frequency transformers (found in the larger switch mode
PSUs) are wound with multi stand wire. The series inductance of a solid
single wire is too high for the transformer to function properly. There is
also the skin effect to consider which is a second reason for the use of
stranded wire.
Similarly, higher frequency signals need to be closer to a ground plane for
effective propagation (think 80 conductor hard drive PATA cables here).

Not had a look at one myself, but is the trace narrower than would normally

Bofore hitting return, I was also going to point out that at the higher
centimetric microwave frequencies, the normal PCB substrate is no good at
all, but microwave circuits can be printed onto a ceramic substrate, but the
traces are very thin and narrow (and made of silver). Once millimetric
frequencies are encountered the traces cannot be more than a few atoms
thick.

But more to the point, a multi-GHz CPU only has those frequencies within
the CPU. Externally, the signal frequencies are much lower.

True, but they are higher in frequency than they used to be. CPU clock

*** I mispoke there. I should have typed "just specified". That is,
the components just meet the requirements or have less headroom than they
once did.
As for the "not tested", I meant at the laptop end. Components are
tested and graded at the manufacturing plant, but it costs the laptop
manufacturers time and money to retest them. So I believe fewer do it,
instead trusting the manufacturers to properly grade them, and that the
components have not changed value between making and installing.
