Acer TravelMate 4151 Laptop Computer Parts
Acer TravelMate laptops were always of great value, because they were based on very solid hardware components, but not necessarily focused on performance.
The Acer TravelMate 4151 is a pretty old laptop, but still offers a satisfying performance with any version of Windows 7 or XP. VISTA isn’t worth mentioning, because it’s one of the biggest failures (or one of the most perfectible products) of Microsoft.
As I said it’s an old laptop, first launched sometime in 2005. At the time Pentium M processors were the maximum the industry had to offer for laptops, so the Pentium M 740 1.73GHz was at the time what a Core i7 Mobile is today. The advantage of these Pentium M processors was the large cache size, 2MB L2, while Celerons had only 256K/512K or 1MB. This was one of the first processors which had exceptional performance despite their low clock speed. It would be interesting to see how much memory does it support today, because the Acer TravelMate 4151 supports two modules, 2GB total, but nowadays 2GB and 4GB modules are also available.
The first problem with large memory modules is that they can be addressed only in 64bit mode, but the 2GB limit should be 3GB or 4GB. It’s interesting to see how much these processors have been improved from Pentium M to Core i7 Mobile. While the Pentium M 740 has only one core with 1.73GHz frequency and consumes 27Watts due to old 90nm manufacturing process, the Core i7-620LM uses 32nm technology, three times smaller, and features two cores running at 2GHz, integrated graphics and memory controller, all under 25Watts power consumption. So in 5 years using the same amount of power these new processors can do around 4-5 times more work.
Acer TravelMate 4151 laptop computer parts include the ergonomically placed keyboard, without a separate keypad, although it can be enabled with Fn + NumLock and used on other keys (letters and numbers). The resolution of the screen is only 1024 x 768, just 172032 pixels more than netbooks have (1024 x 600). When we’re talking about cheap laptops, the Active matrix TFT display is more than appropriate, equipped with fluorescent tube backlighting.<
The main reason why such a laptop computer isn’t really practical today is the high cost of compatible parts. It doesn’t have S-ATA, so if the optical drive or hard drive break, you end up spending more than the whole laptop is worth. IDE drives are very rare, so prices are very high and will still be going up in the next 2-3 years, if they’ll be available for that long.
Battery power on the other hand is something the Acer TravelMate 4151 had. The average battery life is 4 hours (up to 5hours), which is very impressive even according to today’s standards. Because it’s unlikely that you’ll find new parts for it, including the battery pack, it may be a good idea to buy some original Japanese Li-ion cells to refurbish an old battery pack. This way battery life may be extended up to 6-7 hours at the price of a new battery, depending on the quality of the new cells.
The graphics card is a bare minimum for today’s applications. The Intel GMA 900 is enough for movies and some older 3D games like the first versions of World of Warcraft.
Amazon.com still sells all kinds of parts for this laptop, but please note that they are not all new and/or original, so be careful what you order. Quality may be worse than you expect it to be.
hey there and thank you for your information – I have certainly picked up anything new from right here. I did however expertise some technical points using this website, since I experienced to reload the website lots of times previous to I could get it to load properly. I had been wondering if your hosting is OK? Not that I am complaining, but sluggish loading instances times will sometimes affect your placement in google and can damage your quality score if advertising and marketing with Adwords. Anyway I am adding this RSS to my email and could look out for much more of your respective fascinating content. Make sure you update this again soon..
