In January, 2008, the internal hard drive on my circa 2003 Compaq Presario (XP) laptop had a hard drive head crash.. at the time, I was writing articles and reviews and Editing the work of others for a site I will not name.. after trying everything possible to restore it from a full Acronis True Image backup I had on an external LaCie 300 gb drive, (I not only had a full backup of the entire C: drive, but all of my individual files (docs, texts, photos, music, and other data files backed up into folders on the external drive).. everything I tried to bring it back to life failed.. the Compaq's internal drive wouldn't even format!.. it was a 15.4", $1000.00 machine when I originally bought it at Fry's.. the warranty had long-since expired.. it only had a 30 gb internal drive, which was standard for a laptop of that class back then..
I had to have a new, working computer within a day.. I did not have the luxury of time for comparison shopping..
I looked around online, looked for laptops on sale, decided my price limit was about $600.00, and bought an Acer Aspire 5520 (Winblows Vista, dual core AMD Turion 64, 15.4" screen, 160 gb internal hard drive (the standard size at the time), 2 gb RAM, NVidia GForce 7000m Graphics chip, four USB ports.. the usual specs for a mid-priced laptop two and a half years ago).. I ordered and paid for it over the phone with a nationwide chain who is now out-of-business (CC), drove to the store a mile away, and picked it up, brought it home, and migrated my data files over to it from the LaCie external.. obviously, I did not want to restore the XP laptop's full C: system drive to it, which would have over-written Vista with XP, and I used Outlook Express (or "Excess") for email, which morphed into "Windoze Mail" on Vista.. basically the same program with some features changed, but its mail ".dbx" databases could be imported into Windoze Mail in Vista..
The first thing I noticed with the new Acer was that its touchpad driver was insane.. NO change in settings would make it behave properly.. swiping my finger across it caused it to select whatever the mouse pointer was on.. I phoned Acer.. they pointed me to a different touchpad driver on their site.. I downloaded and installed it.. it was just as bad.
I turned off the touchpad with a function key, and switched to using a Bluetooth Logitech Cordless Presenter a friend had given me, as a mouse. That solved that problem..
I had to re-download and re-install a lot of commercial and shareware programs to the new machine, and after x days I finally was back in business.. I put the croaked XP laptop in the corner of the room, figuring that at some future date, I could replace its internal hard drive, and restore its C: (system) drive and OS from the Acronis backup on my external LaCie drive, since Acronis lets you make an emergency boot CD with its own OS and the Acronis program on it to do that job.. (I DID do that about a year later.. bought a Seagate 160 gb internal laptop drive from a respected online vendor, and brought the XP machine back to life, and it now lives in my bedroom, connected to my router with a LAN cable)..
So everything hummed along nicely with the Acer until a few months ago when suddenly, I had a screen full of fuzzy, black and white diagonal bars.. I had no idea what was going on, but I had to power it off and back on.. this started happening more frequently, and randomly, and I couldn't associate it with anything in particular..
The Acer was 2 1/2 years old..
I spend DAYS pouring through various Windoze forums online, using search terms like "Acer overheating" and such..
There were many suggestions by both "experts" and just plain folks as to what the cause of the problem might be, and after consulting with two friends, both of whom can tear a computer apart and put it back together like a Marine can with his rifle, what I found out was that a few years ago, computer mfrs. were forced, by law, to build their machines with lead-tin core solder (I forget the exact proportion), instead of good old lead-core solder..
This is because of a law passed in Europe, because so many failed computers were being thrown away, they'd end up in landfills, the lead would leech out of the solder on the motherboard, and contaminate the water table..
The computer mfrs. did not want to make two versions of their laptops - one for Europe using lead/tin solder, and one for the USA using good old lead-core solder, so they switched to making ALL their computers (in China, of course), with this newer lead/tin solder..
The problem is, after a couple of years, this newer solder tends to develope tiny cracks, and sprout microscopic "whiskers" from the heat inside a laptop that is under heavy use, and left on 24 hours a day.. it doesn't have enough internal cooling.. This Acer only has ONE fan. Its CPU and GPU (graphics chips) do not have micro-fans on them, only Aluminum heat sinks..
Earlier, I had upped it from 2gb to 4gb of RAM, but 32-bit Vista Home Premium only sees 3gb, even with 4gb (two 2gb sticks) installed.. this required removing a HUGE plastic panel on the laptop's belly to get at the RAM slots..
So when it started going into screen-garbage mode, requiring a reboot, I found a freeware program called "CoreTemp" and installed it.. it displays the temperature of each core of a dual-core CPU, and the percentage of "load" on the CPU..
The Acer was running up to temperatures of 200f (!!) and its thermal sensor was shutting down the computer to protect it from frying itself..
More searching.. more reading..
I finally found someone who had the answer, and there were three ways to get around this over-heating problem::
- buy a whole new populated motherboard from Acer, which would cost more than the 2 1/2 year-old computer was worth, take the whole thing apart and install it, but it would still have the same, inferior lead/tin solder..
- give up on it entirely, and buy another new laptop.. these days, what $600.00 bought in January, 2008, you can get for about $400.00, with better specs, but in the interim, I had lost my writing gig, and simply couldn't afford to do that..
- Go into Vista's "power plans / advanced settings", and create a new "balanced" power plan by lowering the CPU's speed from 100% (full speed), to 40%.. this is what I did, and it worked as a semi-permanent, stop-gap measure, and (so far) has saved me the expense of buying another new laptop.. although the computer runs a bit slower, CoreTemp shows it running between 100f and 120f..
I still have a LOT of programs running all the time, but instead of leaving the Acer "on" 24 hours a day, I put it into sleep mode when I retire at night, and use the XP laptop (which I brought back to life with a new hard drive), bedside..
One of my engineer friends explained this lead/tin solder situation to me, and he said that because of this inferior solder all computer mfrs. are forced, by law, to use, that after a couple of years of heavy use and high internal temperatures, and the solder starts developing micro-cracks and whiskers, some of the chips on the motherboard actually rise up off the motherboard, because they are soldered to it with HUNDREDS of solder points.. the computer's thermal sensor says "Eek! What the!? Too hot!!".. and shuts the machine off..
Even if I had bought a one-year extended warranty in January, 2008, it would have expired half a year ago anyway, before this solder break-down problem started..
It had NOTHING to do with the battery.. before I discovered the CPU power plan trick, I tried running the machine off AC, with the battery OUT.. it made absolutely no difference.. the battery is fine and doesn't even get warm to the touch, and still holds a full charge..
I even bought a USB-powered, three-fan laptop cooling pad (dirt cheap), put it under the laptop, and despite it elevating the laptop a bit, and sucking hot air from its bottom and blowing it out all four sides, CoreTemp indicated the cheap cooling pad didnt lower the laptop's internal temperature by more than a degree or two..
I even took that huge plastic panel off the bottom of the Acer.. it was as clean as a whistle inside.. NONE of its air intake or exhaust vents were blocked by dust, furrballs, hair, dead rats, or anything else, but I gave everything a good going over with both a can of Dust-Off AND the nozzle of a vacuum cleaner, just for the halibut..
You have the luxury of some time to shop around, but if you decide on a new laptop, make SURE it has sufficient internal cooling..
Acer simply did not equip this model with enough internal fans.. ONE fan was not enough.. the CPU and GPU should have had their own microfans on them, not just aluminum heat sinks..
My MUCH older XP laptop is on 24 hours a day, and it was built with the older lead-core solder, and ha NEVER over-heated.. NEVER shut itself off.. not once.. I don't use it as my main "living room" machine, since it only has a single-core processor, two USB 1.0 ports, and 512mb of RAM, but it DOES have a MUCH more powerful fan in it than the much newer Acer does, and I run just as many programs simultaneously on it as I do on the Acer..
I would NEVER buy another Acer computer, and due to lack of income, I'm not currently in a position to replace this one, nor to have a whole new motherboard installed in it.. It has a ton of USB devices connected to it, including a new Seagate 1 tb external drive I bought a couple of months ago..
Parenthetically, I have an elderly College Professor friend who just paid nearly $1800.00 for a brand new iMac 21" all-in-one, plus "Apple Care", which came with a (too small) Bluetooth wireless keyboard (which is actually smaller than a full-sized keyboard, and I found it impossible to touch type on the thing, due to the size of the keys).. and Apple's "Magic Mouse".. I was at his house last week and played with the thing for a few hours.. Apple makes very pretty stuff, and I understand the whole "cult of Apple" thing, but their stuff is expensive.. he switched from an old Windoze XP tower to the iMac and is totally lost in that new environment.. a friend of his also talked him into buying an iPod Nano (the final "wheel" model).. and he doesn't even have a clue how to get music onto it, much less even rip CDs, so I'll probably visit him again and run him through how it all works..
But I digress.. sorry..
The point I'm trying to make, and I apologize for the length of this posting, is that if you intend to buy a laptop, and use it heavily, make SURE it has sufficient internal cooling if you're going to keep it on all the time.. ALL newer computers are made with this inferior lead/tin solder on the motherboard. Desktop or "tower" machines are MUCH easier to expand, and have MUCH beefier internal cooling than most laptops have..
Also, beware of computer reviews written by writers who did not shell out their own money for the machine.. especially, if the mfr. of that machine is one of their site's or magazine's advertisers.. the reasons should be obvious.. if not, many reviewers are afraid of offending their advertisers by giving that advertiser's hardware a thumbs-down review, to the point that they might lose advertising revenue..
The chore of shopping for, comparing, and buying a new computer has become a hundred times more complicated than it was, oh, ten years ago.. the choices are endless and confusing, and there are as many opinions as people who spout them..
So that's my story, and my experience. I paid hard-earned money for this $600.00 Acer in January, 2008, and two and half years later, it developed thermal problems due to insufficent cooling, and poor design.. Of course, when it was brand new, ALL of this model were brand new, and the fact that it would start over-heating after two years was not known then.
Google around for "laptop overheating" and you will find thousands of postings all over the place, by people suffering from the same problem, the root cause of which is poor design, and the mandated use of lead/tin core solder, which breaks down after a couple years of insufficient internal cooling (bad design, weak / not enough fans), and higher and higher speed chips which generate more heat than the under-engineered machine can handle..
My apologies for rambling.. my intent was to inform, not to confuse..
Best Wishes..
