I don't usually have a need for a laptop, so I haven't ever bought
one. However, over the years I've been given two by people who
upgraded and no longer had a use for the old, obsolete ones. I've
noticed that when they started to die, they both exhibited almost the
exact same problem, and I'm wondering if this is common for laptops
dying of old age. Also, I'm wondering if the cause is simply because
the CMOS battery (or if it's called something else, the equivalent of
the separate battery that keeps the clock's time correct and preserves
the contents of the BIOS setup info, commonly called NVRAM these days)
has died.


The first one was given to me around 1996 and was an MS-DOS based one
made in the 1980s. It had REALLY big external batteries that hooked
onto the back and in spite of the former owner's claim of EGA, it only
had CGA graphics. After a couple years of using it, it started having
a problem. First the clock was losing the time, then a bit later it
would refuse to start up more than activating the screen and fan. It
would not run POST, and would not start the bootstrap process and
search for MS-DOS either on disk or the hard drive. The backlight on
the screen would light up and the fan would run, but there would be
nothing displayed.

Around 2004, I was given another obsolete laptop. This one was most
likely made around 1998 or 1999, since it came with Windows 98 First
Edition. it worked fine, but did not have an ethernet card, much less
wireless and the person was switching to broadband. Hence why she gave
it to me. I also didn't have much use for a laptop at the time, and
not being able to hook it into my network made it even less useful
since I couldn't get onto the 'net, but she was going to toss it and I
was in school at the time, so I didn't know if it might come in handy
or not. It eventually wound up sitting on a shelf in my closet until
today.

Lately I've needed to run Microsoft word away from computer access,
which will only be once a week for about four months, so rather than
buying a laptop, I pulled that now REALLY obsolete laptop out of
storage. After charging the main battery, I noticed that the clock was
messed up. I reset it. I've been using it once a week since September
and needing to set the clock each time like a REALLY old MS-DOS
machine, but last week the laptop seemed reluctant to power up.
The symptoms were the same as with the old MS-DOS based laptop.
Powering it down and hitting it on the bottom like an old TV set made
it power up. I don't know if the hitting had any effect or not. or
just the powering down using the [crash] override.

This week it took several attemps to get it to power up with people
looking at me oddly as I tried to get it to boot. I should also add
that the new laptop gives me no opportunity to get into the BIOS setup
until it starts to work normally, and when I do, the default settings
all seem ok.

Is this a common symtom of laptops when their CMOS batteries die, or
is it just coincidence that the two old laptops I've been given over
the years both broke down the same way? I do mean the CMOS batteries,
not the main batteries that power them when not plugged in. I was able
to use the laptop tonight for about an hour and fifteen minutes and
according to Windows battery meter taskbar app the battery still had
31% power remaining when I shut down. It had read 98% when I finally
got it to boot at the beginning.

No, I don't think that what you experienced had anything to do with the
CMOS batteries (although I can't rule it out entirely). Most laptops
will work fine with no CMOS batteries at all (but there ARE exceptions).
Of course time will be lost, and very often you will have to go into
the BIOS and at least "restore defaults" every time you power the
machine on, but normally it won't keep you from booting.

Laptops do have CMOS batteries. For reasons that are to me
unfathomable, very few laptops allow for these to be externally
replaced. Worse yet, on some machines they are soldered to the
motherboard. They may be either single use lithium batteries (coin
cells, although, again, occasionally soldered in place (but sometimes
not), or rechargeable (Toshiba is a fan of rechargeable batteries
(usually NiMH coin cells). In most cases they charge only when the
laptop is actually ON (not plugged in, but truly ON), they take 48 hours
to charge fully, and they will then work for 2 to 4 weeks without any
further charging.).

A common cause of problems in newer machines is severe overheating. All
modern laptops have fans and heatsinks, and after 6 to 24 months, the
heatsinks get clogged up with dust and dirt and hair, in some cases so
bad that the fan blades can no longer even turn (I've pulled a couple of
cubic inches of dust / dirt / hair out of them when cleaning them).
Then things overheat and, sometimes, die. The problem effects both the
CPU and the chipset. Cleaning the CPU cooling system is easy on some
laptops (remove an access panel and you can get at everything) and
nearly impossible on other models (you have to remove the screen from
the base, disassemble the base, and in some cases actually remove the
motherboard to get to the fan and heatsink UNDER the motherboard).
Another problem is failure of BGA (ball grid array) chip mountings.

However, your laptops are older, and are likely so old as to not have
these particular problems. Note, with respect to the battery, that if
the battery has become SO deteriorated that it is leaking corrosive
electrolyte ... that's a different problem.

One other thing to keep in mind is that laptops have power supplies just
like desktops. The battery and AC adapter only provide inputs to these
power supplies; the internal circuitry runs off of the multiple outputs
of these power supplies, generally +3.3v and +5v (sometimes +12 also).
As motherboards and power supplies have had problems with bad
capacitors, so to can laptops, so this is another potential common problem.

Some older laptops like the IBM models error out if the CMOS
battery is dead. Others behave like a desktop and just ask you to
stop in firmware.

Well I have had 7 laptops since '84 and only one from the 90's cooked
itself after five years. Toshiba forgot to include a fan to that oven.
The two from the 80's didn't have fans either, but they run cool anyway.
All of the rest of them are still running fine.

Some people have trouble getting laptops to last 5 years. I don't know
what they do with them actually. Once in awhile you run into a poorly
designed model like I did once. But that is the exception IMHO rather
than the rule.

As Barry mentioned, some models create lots of heat. I stay awhile from
those models. As they won't last 25 years like one of mine has. And the
weakest link in most laptops is the lamp inverter and the florescent
lamp itself. And they generally only last 10,000 to 25,000 hours anyway.
I use external monitors a lot and it keeps the hours low on the laptops.
Nowadays, virtually all netbooks and some laptops use bright LEDs
instead. So this limitation should disappear.

Actually, not only powered on, but the screen's lamp must be on. As I
learned this because I use external monitors a lot. And the CMOS will
drain completely in say 6 months or so if the screen is never lit. And I
found 12 hours is good enough to charge up the CMOS/RTC battery for
another 6 months or so.

Regarding your laptop w/o internet access and running windows 98, I
managed to find a PCMCIA wireless card that I was able to get working
for an old dell laptop Latitude CPi. It was a generic wireless card w/
o a brand name and made in china, but it works good. The main
problem I had after connecting to the Internet was getting an uptodate
browser. The laptop came with IE 5 and will not work with a lot of
websites and the new IE version will not work with Windows 98. I was
able to find an old version of netscape in an archived site that works
reasonably good with websites and compatible with windows 98. So even
with Internet access, some more up to date websites dont work well
with older versions of web browsers.

I'm currently using Firefox 2 on my Windows 98SE Desktop.
The laptop only has First Edition, and my desktop came with Win98SE
preinstalled with the only means to reinstall it in the C:\WINDOWS
\OPTIONS\CABS folder.
Thus I don't know how to make a Windows CD using Dell OEM Win98SE to
upgrade an NEC laptop to Second Edition.

I'd be more interested in details on a PCMCIA ethernet card and
wireless card if I wasn't having power-up problems.

Dell OEM Windows 98SE files won't work on a NEC anyway in all
likelihood. Microsoft sold an upgrade (Windows 98 to 98SE) disc for 10
bucks for like 3 months (over 10 years ago). You might find one on eBay.

They are nice. Somebody borrowed mine and I never saw it again. :-(

I'm pretty sure it's just a single type-III PCMCIA slot. The thing has
quite a few connectors on it including a serial port, a parallel port,
2 USB ports, a docking port, a VGA-style monitor port, a PS/2 port
(oddly enough only one with symbols for both keyboard & mouse), and an
S-video port. It also has a built-in 56K modem which was used for
internet access by the previous owner that appears to have provisions
to be removed. I think there might be one other port I'm forgetting,
but I don't feel like pulling it out of the case right now. I won't
need it again until Wednesday night and I've already moved the files
to my WIn98SE computer via sneakernet. I'm giving serious
consideration to buying an external 3.5" drive for my new Gateway
since it's the first computer I've ever owned without one.
It's an NEC Ready 440T
Quite nice for the era it was from.

My reply is not about anyone here, much smarter people than the average
laptop owner/user.......that said:

Watch other people use their laptops. They have them in their laps!
Make a note of make/model so you can look on the bottom of them where
their legs are covering up the FAN INTAKES the laptop maker IDIOTS put
perfectly placed so you cannot lay one on your lap and type on it
without covering up the COOLING INTAKE. Who designs these things? Do
they ever use one?!

Next point - Laptop cooling gadgets. Have some fun on your next trip to
the computer mall outlet. Look at your computer, SUCKING air from under
it to cool it. Now, find any cooling gadget that BLOWS air INTO that
intake. Check them out...we'll wait. MOST of the ones I've seen these
people are using SUCK air OUT of the fan INTAKE and blow DOWN, not up!
NONE of them, luckily, have the fans positioned to match the cooling fan
intakes of real laptops sitting on it. How stupid.

Point 3 - How many people do you know who operate their laptop on a SOFT
SURFACE?....Carseat, couch cushion, bed, etc. How can the fan suck air
through a plastic carseat or those fancy satin sheets pushed up against
the intake grate?!

No wonder the ****ed things overheat! STUPID design, Stupid users....a
disaster in the melting....

Ah, but now there are netbooks with cooler, SLOWER processors that don't
have air pouring out of them that can shrink shrink tubing around a
solder connection....a more SANE, sedate way to look through that data
pinhole into the internet. Add the biggest aftermarket battery so it
TILTS the netbook up off the bed and the fan can even breathe...what
little it's turned on.

No matter which direction the fan blows...as long as it doesn't
directly suck where the laptop sucks...it will allow better air flow.

Do you use these laptop cooler things Bob?

My two Gateway MX6124 and four netbooks work well off of your lap. I
monitor the temp sensors and they are fine with it. Although I have had
some laptops that doesn't take too kindly of sitting on your lap.

It doesn't make a lot of sense to have two fans (or more) playing
tug-of-war with each other, does it?

I hate this limitation! I created two longer feet for the back end of my
Gateway laptops that raises it up about two inches. And it does wonders
for the temperature. It even stays cool lying on the bed.

My four Asus EeePCs are okay on a soft surface. So no major problems
there. Some even run them without the fan connected and have good
results by doing so.

One thing you haven't mentioned that even on a hard flat surface, most
machines still gets very hot. Manufactures seem to want to make the
machines hug the table/desk as close as possible. Thus there is only a
sliver of space between the bottom and the hard surface and it traps
lots of heat under there. When you increase the space like I did with
the Gateways, their CPU temperature dropped by 15°F.

Ah, but Asus EeePC Celeron netbooks are great. They don't need much air
flow, can block the vents and very little or no measurable increase of
temperature is detected. Those under clocked Celeron CPUs helps a lot in
this regard. As they just don't create enough heat to do any real
damage. I do clock them up to speed sometimes and then you need to have
the fan running and the vents unblocked. But they do run well under
clocked, so no real need to do this.
