You gotta maintain and take care of your possessions – that's my motto , and one of my possessions which I deeply care about is my good old laptop computer.
Since laptops supposed to be mobile and are very delicate and therefor highly breakable they are pron to be damaged quickly if not maintained and taken care of properly.
I have been witnessed to many cases in which my friends and people I know were just careless about how they maintained their laptops and even more careless about how they handled it in their daily routines.
One of the most common “laptop accidents” involves liquid being spilled in the vicinity of the laptop or worse – on the laptop's keyboard. The laptop's keyboard is one of the more sensitive spots of the machine due to the fact that it is not a completely sealed area.
Furthermore , that unsealed area is very big and is spread almost across the entire length of the laptop.
Besides liquid , dust and micro-dust are also a reason for concern. Dust presents a problem when it comes in contact with electronics and mechanical moving parts of a computer. It accumulates slowly and over time it prevents an efficient heat dissipation and causes moving mechanical parts like fans and optical drivers fail.
The micro-dust goes where the bigger dust particles cannot enter. Usually these tiny particles find their way to the optical drive's laser reader , extension socket etc.
because of the issues I mentioned above , I bought this:
it's a keyboard cover made of silicone created especially for Dell Inspiron laptops. Of course there are covers that were designed for other laptop models of different brands as well.
It fits EXACTLY on the keyboard , the translucency of the keys is pretty satisfying especially considering the fact it is made out of silicone , it prevents dust , micro-dust and liquid from entering beneath the keyboard and into the laptop itself.
Using it prevents the letters printed on the keyboard to be wiped out over time and it also appears to absorb the key's typing noise.
The edges of the cover are thick and deliver more friction because of it which translates to a good grip of the cover on the keyboard.
I type a lot with this laptop , mostly during lectures , and not once the cover lost grip from the keyboard's surface.
Due to the fact it is made out of silicone the cover can be easily cleaned using water and an ordinary soap.
Oh , and of course , it is very cheap – cost me 3.49$ on Ebay, I believe it's quite a cheap investment in your laptop's survivability.
So to sum up...
Pros:
.1 cheap – a little over 3$
.2 protects keyboard from dust and liquid
.3 absorbs sharp keyboard typing noise
.4 protects printed letters on the keys
Cons:
.1 prevents heat dissipation from underneath the keyboard
.2 not entirely transparent and some people would even say it makes the whole appearance of the laptop ugly
.3 it gets dirty pretty fast
.4 unless you use some sort of a cloth to physically separate between the laptop's monitor and the laptop's body when closing it, you’d find out that closing the laptop's monitor over the laptop's body while the silicone cover still there and leaving it for some time create stains on the monitor due to the contact between the silicone cover and the monitor.
Despite the downsides of this product I would highly recommend it for anyone who cares about his\her laptop. The downsides can be easily overcome by cleaning the cover often and using a cloth when closing the laptop's monitor. And about the appearance issue...well, nothing is perfect , I admit it doesn't make the laptop prettier than what it was before using this cover but it it beats having no functioning laptop at all because bad handling and misusing the laptop...

If you read my "Upgrading a Dell Laptop" post then you'd know why i bought this product for.
For those who you who didn't , i'll explain.
Part the upgrade included replacing the old HDD hard disk with a new SSD hard disk that has significanly lower volume (320 GB in the HDD vs 90 GB in the new SSD).
Since i need a lot of space i purchased a SDHC card that has 64GB and plugged it in the Dell's built in SD card reader.
Time has passed and those 64GBs weren't enough so i decided to but another 64GB SDHC only i had nowhere to plug it in.
So i searched and found this on E-Bay:
installation was simple , plug and play.
Cost - 10$
Pros:
-
can be used to extended a laptop's storage volume
-
can support SDHC cards , and other 24 types of cards
-
supports bigger storage volume cards
-
easy installtion
Cons:
-
the SD card can be pushed inside the adapter only half way through , apart from being not aesthetic , it presents an opportunity for someone to just extract it out and steal it. Because of this "bulg" that is created because of that , one has to be careful when putting the laptop inside a bag vertically not breaking the card (putting the laptop with the sd card's "bulg" side upwards can fix this problem)

This is a very cheap and yet a very useful product. I bought it for mainly 2 reasons:
1 –my laptop would get very hot
2- during lecturers the laptop almost slipped a few times off the small inadequate tables (you know , those ones you see in every college or university and it is usually connected to the seat).
For the price I got 48 pieces of small , rounded thick rubber feet which I could use on anything I need. My first priority was my laptop of course. After sticking some 17 of those under it I could really notice the difference. The laptop's temperature was much cooler and while being in lectures the laptop didn't move off the table cause of the friction they created.
The product was found on E-Bay for some 18$ for 48 pieces.
Of course they could be used for many other applications like furniture and other home applianceses.
Upgrading a Dell Laptop

Upgrading a Dell laptop with an Solid State Drive (SSD):
In this post i will show how you can take an old laptop (3-4 years in my case- 2009) that runs very slowly and turn it into an efficient machine with a relatively low cost.
The project laptop is a Dell Inspiron 1545 and here are its specifications:
· CPU – Intel Mobile Core 2 Duo T6400 at 2GHz
· Chipset – GM45
· HDD – 320GB Western digital
· Ram – 4GB DDR2 at 400Mhz (PC6400)
The above are the core specifications of the machine, other features as monitor and other peripherals are not important for this post.
When i bought this laptop back in 2010 it was sufficient enough for my needs. Back then it came with Windows Vista Home Basic and running multiple programs at the same time was not a big issue. When i say multiple programs i do not mean a lot of instances of Mine Sweeper , i mean heavy applications such as Adobe Photoshop , Dreamweaver , Winamp , Firefox with at least 10 tabs opened , among them tabs with flash player which takes a lot of resources.
Over time running all the above simultaneously , even after a format job - became a major pain. Besides the mentioned , one cannot forget the antivirus , anti-spyware , skype , firewall and other "behind the scene" services which run in the background , each one takes a little portion of overall resources and together they present a heavy burden on the entire system.
I tried everything from defragmenting the hard disk a few times a week to cleaning the operating system from garbage files – nothing helped increasing performance at a noticeable rate.
It was time for the inevitable upgrade.
I wasn't sure how the inevitable upgrade looks like or costs back then. First i had to research a little bit about the laptop's motherboard and upgrade capabilities. Because it is a laptop those capabilities are quite limited to a few – cpu , ram and hard disk.
Let's start with the ram – i soon found out that 4GB was the limit RAM of the motherboard so i dropped it off as an upgrade option , let alone because of the fact that adding more ram to the system wouldn't contribute much to the overall performance...so knowing that was pretty comforting.
Cpu – one word – expensive.
My laptop's specific cpu is a T6400 that runs on a 2Ghz frequency that was made with a 45nm technology and has 2mb of cash... all that on a 478 pin socket...
i browsed the Intel website for cpu upgrade options and what i deduced that any cpu replacement at the time would be Indefensibly expensive and possibly increase the overall power consumption which would lead to a faster battery drain times , and as a college student , i need as much buffer power as i can get ( long lectures... no power plugs around)
so i was left with the last option - the hdd. As i write this post SSDs are still expensive relatively to their storage capacity, on the other hand regular Hard Disk Drives were never cheaper relatively to their storage capacity and i was very tempted to buy one of these.
My old western digital HDD was a simple 2.5" 5400 RPM hard disk that when made wasn't aimed at producing peak performance.
I made a little research about performance gains as a result of replacing a 5400 rpm hdd with a 7200 rpm hdd... i wasn't impressed and my mind had focused on the SSD option earlier so i dropped off the 7200 option also..
Since SSDs are expensive i had to sacrifice storage capacity for price , performance and low power consumption.
The network is filled with SSDs that use SATA3 interface which is damn fast ( 500 MB\S) and since my computer uses Sata 2 , buying a SATA 3 SSD would be a waste of money and potential , but soon i realized that even the SATA 2 SSDs are quite expensive.
After browsing E-bay for some time i came across a batch of SSDs which weren't that expensive , their capacity was limited (32-100GB) and they were MANUFACTURER REFURBISHED , which was also something new to me.
I searched the web for the answer to how much liable using this kind of product really is and if is there a risk using it for a long time. It seems that people do buy these refurbished items and spend a lot of money on them . Products that usually cost 50% or 100% more can be bought in a very cheap price , producing the same result as a new product.
For all of you who wonder what a "manufacturer refurbished" product is , it means that it's the same product only the difference is one of the following is true:
1- it has been used before by a consumer and was returned to the seller for some reason , usually product liability.
2- it was detected with a defect by the manufacturer and was taken off the assembly line for repair
3- Overstocking of a distributer or a seller
I made a lot of thinking before actually spending my well earned money on a type of a product i never bought before and eventually i bought this on E-bay:

Physical and Operating system Installation:
· It took me about 5 minutes to replace the old hdd with the new one. I just had to screw out 2 screws , pull out the old hdd , and push in the new one...
· The next thing was installing the operating system. At first I hesitated whether I should upgrade to Windows 7 or not...eventually i stayed with my old copy of Vista instead for no apparent reason except I got used to it.
· The installation process was noticeably shorter and after finishing with the installation of the OS , installing the other major applications took also less time than I was used to.
Performance:
· No doubt , my machine was FASTER , way faster than was it used to be before the upgrade.
Windows are opened in an instant instead of waiting 5-10 seconds before ; Adobe Photoshop CS6 takes about 15 seconds to generate the user interface (the splash screen stage).
· I could run many applications at the same time with ease and switching from on to other took less than a second. Here is a list of what I opened and worked with simultaneously :
Opera , Firefox , Chrome , FileZilla , Word , Winamp , Photoshop , Dreamweaver and of course all of the other applications that run in the background – Zonealarm firewall , Nod32 anti-virus , skype and Dropbox. The web browsers contained 5-15 tabs each , some with Flash player opened.
Power Consumption:
· When I installed the new SSD my battery was already depleted because of over usage. Before the upgrade, after a full recharge, it could sustain power for about almost an hour long with battery settings set to maximum saving (in Windows Vista). Again, this is after 2 years of usage, when it was new it could sustain power for almost 2 hours.
The old battery was a regular replica of a DELL with 6 cells.
After installing the SSD I replaced the battery with a new 9 cell genuine DELL battery – the results were pretty surprising... after a full recharge in a maximum saving mode , the new battery along with the less power consuming SSD could sustain power for over 4 hours long...that's a big leap from barely 1 hour to over 4 hours...
Since my Dell is an old model it doesn't have a “monitor turn off” button, so I had to Google search on how to make one. Eventually I created a shortcut to a command that turns off the monitor. It sounds a little stupid and unnecessary, but it actually saves a lot of power... it's a much more logical solution in student environment when you don't really want to wait for the monitor to turn itself off or putting the machine into hibernation mode during a lecture.
To sum up , instead of buying a new laptop spending thousands of dollars , I spent just a little over 100$ turning my laptop from a slow , inefficient, power and time consuming machine to a fast , efficient and power saving one.
Dell 9 Cell Baterry

Up until now I used to buy only 6 cell batteries. This time I decided to go with a 9 cell one.
My main reason was the long lecturers i was present at which made my laptop run out of power after only 1 class.
The decision was right. With a 6 cell battery my laptop would run out of juice after maximum of 2 hours while working in power saving mode. This is new 9 cell battery changed my laptop's time frame to 4 hours maximum work in power saving mode – a really big difference.
The only "disadvantage" this battery has is its size. Since it needs more room for more cells the manufacturer added a bulk at the back of it which makes it physically bigger and heavier. From my daily experience these facts do not present a significant Burdon.
The product was worth the money – was found on E-Bay for 41.54$. It is a genuine (at least they say it is) 85Wh , Li-ion Dell battery that works on 11.1 volts.
