The simple steps of repair the heat sink / fan

By laptopsbattery - September 28th, 2010, 23:38, Category: General

A few months ago My Inspiron 6400 battery heat sink / fan went bad. Unfortunately it was out of Dell 1 Year warranty. I called up Dell Tech support for some help, a customer sevice manager reply me with $ 1650 cost and 2 week to repair it. $ 160 is rather too expensive than my expectations. So I decide to repari it by myself.

First I spend 1 hours browsing Ebay to buy the heat sink / fan for my Inspiron 6400 (It is the same as Dell inspiron E1505 battery). It cost me 7.56 dollars. Let me start my heat sink/fan DIY. I briefly read some artcile about how to disassemble the Dell laptop. I compute the workload of the replace the heat sink/fan part. Obviously I can done it in 3 hours.

So I droped all the thing away, as I should to remove and replace 50 screws and even all the components of the CPU fan.

The photo above is a picture of my Dell 6400 battery. This was taken after removing the cooling unit on top. The next two photos are of all the components I had to remove.

Letís see, this photo shows the LCD, the HDD, the EMP shield, the new thermal cooling unit, and an upside down keyboard. The button panel should be hidden in there somewhere too.

Well, I reassembled the thing back together, I put some thermal paste on the stump. Almost all compounds on previous thermal heat unit were lost, so I thought I'd better do fix it.
After an hour I took whole things better, I booted the machine and it worked (which surprised me). Then I was prompted to turned if off for fear of overheating ( this happends on my last Dell inspiro 1501 battery), so I did have time to test it since it was ok.

At the moment I am in the process of setting up a dual boot of Windows and Ubuntu. And my Dell inspiron 6400 battery was back to work.

Portable external batteries are very inexpensive and can be loaded by an external HP pavilion dv4 battery charger. A laptop user can take a decision on the chemical used to manufacture these batteries such as nickel cadmium or NiCd batteries, nickel metal hydride or NiMH, Lithium Ion or Li-ion batteries.

The price of an external battery pack can range from $ 120 to $ 200 and these batteries are available online as well as in the regular market. As computers and other devices are becoming cheaper, the prices of laptops are also falling. This means that more and more people are using laptop and longer. These Compaq presario cq40 battery are ideal for those who want an extended power source for their laptops when traveling.

An external laptop battery connects to a laptop via AC adapter and usually have two levels of production. It consists of an adapter, a chord and thirteen other connectors. Another advantage is that these Compaq presario cq50 battery are universal. This means that an external battery that is manufactured by a company can be used with a laptop from another brand and model.

Portable external Compaq presario cq60 battery are revolutionizing the world of IT, providing greater mobility and extended power for those who want to use the laptop for more than two hours without worrying about power outages.

Laptop batteries are getting cheaper

By laptopsbattery - September 20th, 2010, 23:37, Category: General

A battery is Minor important components to the processor, the heart of notebook. If you not only use the laptop as a desktop computer just with power supply, the laptop has to rely on the functionality of this powerful mini-power plant. But batteries aging can reduce the laptop battery life necessarily. Though you can delay this process by following numerous tips on battery care. You had better to buy a spare battery sooner or later.

As a rule of thumb applies: Every two years a new battery should be charged. Generally the battery life is 300-500 charge cycles. For example, Laptop battery deal, there are over a thousand different battery types for all leading laptop manufacturers. And not just for new coming models, but also for laptops, which have come in the days.

Highlights include the batteries for IBM Thinkpad R50/T40/T41/T42/T43-Serien. Three battery types with different values of Ah (ampere-hours) are available for these models. The Ah-value designates the number for the battery or battery capacity. It provides information about how long the battery last or a charged battery can be discharged with which adapter. This generally applies: The larger the value, the longer the battery life. For the aforementioned IBM Thinkpad series batteries with 4.4, 5.2 and 6.6 Ah are on offer. While the latter has about 50 percent more capacity than the standard system battery with 4.4 Ah.

So do not worry if the your Inspiron 6400 battery life reduce more and more. It's always too quick to work. Treat yourself to prefer a 100 percent compatible replacement battery. It is cheaper than you think.

Choose the right laptop batteries to get more power for mobile working

Choose the right laptop batteries to get more power for mobile working

The technology of the energy supply is one of the major obstacles in the Mobile Computing

Whhich laptop would be a good Machine (with a large memory, a powerful processor and good software without a battery?) Only the laptop battery could successes start the laptop. For without this small but important unit, the high mobility and portable computer anywhere in the world would not be possible.

Modern laptop batteries are now working almost exclusively with lithium-ion batteries. This power storage are lightweight, have a high capacity, have a short loading time and are considered maintenance free. However, they are relatively expensive and age rapidly. The operating principle is similar to the battery at a crucial point in the battery: Chemically stored energy is converted to electrical energy.

With rechargeable HP Pavilion DV9000 batteries and the reverse process is possible, ie that electrical energy back to chemical energy is - why are both unloading and loading operations possible. For charging a battery, electrons are pumped from the negatively charged electrode (cathode) to the positively charged electrode (anode). This results in the reactivation of the discharged electrodes, creating a tension between these two electrical elements. Once the electrical circuit is closed, the electric current flows.

The life of a battery significantly depends on the number of charge-discharge cycles and operating temperature. Depending on the type of HP Pavilion DV5 battery, the charging and discharging take place up to 1000 times. Depending on the use of a battery usually lasts two to three years. Thereafter, capacity and service life have been exhausted. Is the first laptop battery is defective, it can be in most cases beyond repair. The Internet or from electronics stores, one will quickly find a new battery find. Either one can choose an original battery of the manufacturer or for the equivalent of a third manufacturer. The sale is: the laptop battery needs to be tuned exactly to the particular computer.

For people who work a lot with your laptop battery, we recommend purchasing an extra HP Pavilion DV4 battery. Again, the above: the new auxiliary battery must fit the laptop model. It is possible to buy an extra battery, which are used in the device. External Laptop batteries are connected externally to the laptop. This dualism in the device is powered by two batteries.

HP recalling 54,000 laptop batteries

By laptopsbattery - September 12th, 2010, 23:30, Category: General

SAN FRANCISCO (AP) -- Hewlett-Packard Co. is recalling 54,000 lithium-ion laptop batteries used in HP and Compaq computers after receiving reports of injuries from the batteries overheating and rupturing.

The recall was announced Friday by the U.S. Consumer Product Safety Commission and expands an earlier recall of 70,000 of the same type of laptop batteries.

The earlier recall came after two reports of the HP laptop batteries overheating. The commission said that since then, HP has received 38 additional reports of the batteries overheating, causing 11 minor injuries. Those people were burned when they handled computers whose batteries had ruptured, said CPSC spokesman Scott Wolfson.

Batteries can rupture if they've been charged too long and don't have a good way to regulate the excess heat. HP says the computers at issue were sold in stores and online from August 2007 through July 2008. The battery packs were also sold separately.
