How to replace the speaker from a laptop

As far as we know the laptop self speaker are low quality and Easily damaged part. We always use it to call in the internet with our friends and family. The bad speaker can not transport the clear avoice to the chatting person by the internet. So we usually will replace a good speaker and laptop battery the time we buy a new laptop.

My work need to use Skype to connect the foreign Customers usually. So we should replace a new high quality speaker for my Lenovo ThinkPad T60 battery. I buy a new sony laptop speaker from www.laptops-battery.co.uk and replace it by myself. The whole couse will be done in two steps : 1. Removing the speaker from laptop. 2. Replace the new speaker on the motherboard.

The temperature affection for different battery

Nickel-metal hydrides are less tolerant than nickel-cadmium in terms of the charge at low or high temperatures.
Nickel-metal-hydride can not load quickly at temperatures below 10 ° C, nor can they load slowly below 0 ° C. Some chargers are designed so that they Ladekoeffizienten and the ambient temperature change. Price considerations are not allowed to provide Apple PowerBook G4 12 inch Battery battery chargers for consumer electronics with temperature sensors.

At higher temperatures, the charge acceptance of nickel-based Apple PowerBook G4 Battery is drastically reduced. A battery that can hold at room temperature, a medium capacity of 100%, starts at 45 ° C ambient temperature, only 70%, and even only 45% at a temperature of 60 ° C. This highlights the poor performance of some car chargers in the summer!

Lithium-ion Apple PowerBook G4 15 inch (aluminum) Battery provide a good charging in to deep as well at high temperatures. Some cells allow charging with 1.0 C from 0 ° C to 45 ° C. Most lithium-ion cells, however, prefer a lower charge current when the temperature at 5 ° C or falls below. Must be dispensed on the loading below the freezing point, as a coating can be effected by lithium metal.

The lead-acid Apple PowerBook G4 17 inch Battery is not very sensitive to extreme temperatures, as we all know, on the basis of experience with our car batteries. Part of this tolerance is the inertia of lead-acid systems are attributed. Some battery models allow a shop below the freezing point with a small charging current, while others are damaged, and provide only reduced capacitance values, and life expectancy is shortened.

To improve the loading performance of lead-acid Apple PowerBook G4 17 inch Battery at low temperatures and prevent thermal effects during the warm-up, it is important to monitor the charging voltage limits to be set. An installation of this measure can extend the life expectancy of a battery up to 15%. General guidelines recommend making a correction of about 3mV per cell per degree Celsius. The voltage correction has a negative coefficient, ie The threshold voltage decreases when the temperature rises.

Heat kills the Apple MacBook Pro 17 inch Battery! The warmer the cells shorten, the life expectancy. Higher temperatures may not always be foreseen, especially during a fast charge. It must, however, attempt to keep these periods as short as possible. While 45 ° C is temporarily tolerable, begin a battery from 50 ° C damage is increasing. Moreover, cells are warmer in the interior of a battery, always a few degrees when the temperature of the battery case.
Ultra Fast Chargers

Some manufacturers of chargers promise amazingly short loading time of 30 minutes or less. With well-balanced cells and moderate temperature can nickel-cadmium VGP-BPS10 s batteries, which are designed for fast charging, are being charged in a very short time. This is achieved with a simple increase of the charging current during the first 70% of the charge cycle.

12Cell 98Wh Dell Inspiron 5100 Lithium battery review

Dell’s first model in its revamped consumer notebook range, the mainstream Inspiron 5100, is different both inside and out. Gone is the buttoned-down grey case, to be replaced by a two-tone ‘Venice blue and moonlight silver’ design. Also a little mistake is that the Dell inspiron 5100 battery is too heavy to make the notebook a little importable.

Last Saturday I went to a schoole to do a PPT lecture. So I should buy a battery replacement for the trip. I just use the battery a little so I do not decide to buy a expensive Dell original one or buy a replacement from some other manufacturers. I searched the “Dell inspiron 5100 Battery” in Dell.com and Amazon .com and found many interesting customer reviews.

The picture just from a online shop : www.battery4.us

The Dell Inspiron 5100 battery specs :
Technology : 12-cell lithium ion
Voltage: 14.8V
Capacity : 98Wh
Max Recharge Cycles : 500
Weight: 722.91 g
Fits Model : Inspiron 1100 Battery , Dell inspiron 5100 Battery

From the below specs you can see that the laptop battery is a big and heavy battery with 12 cells. It also can last 3-4 hours showing the PPT documents ( I have test that). In all the battery is not a good choice as its weight (same as the adapter and lines). Let me see the customer reviews of the Original one and replacement.

The original One review:

This Inspiron 1100 Battery worked first time. Two batteries from cheaper sites didn’t work at all and we had the duty of returning the defective batteries. Dell’s was more expensive but worth it!!

VERY EXPENSING! Double the cost of a car battery. But you need it if you want your older computer to be portable. My new lithium-ion battery for my dell inspiron 1100 laptop has a 2 hour and 15 minute capacity.excellent! that’s all the time i need for wireless.

The Dell inspiron 5100 battery replacement from Amazon :

Ordered this Dell Inspiron 5100 Battery for my laptop. Arrived and it was dead. Contacted company to return it. Communication on how to return the product was timely, but when I got a replacement battery that was dead too. I was able to return it and even though I got all my money back in full it was a lot of headache going back and forth with the emails and having to twice make a trip to the post office to ship it back. It took a over a month to finally close this issue. Even though I got all my money back in full and the emails on the status was very communicative it was a pain. It took two dead batteries to be delivered to a customer before an email from customer service stated that maybe the batch was bad and it needed to be looked into.

The price was right, the quality was great, and it arrived quickly. Far less expensive than buying from Dell. Thanks! Battery works perfectly, fits perfectly and lasts longer then the factory battery ever did. It is rater higher too.

Customer review :

I would not get this product. I would not buy a laptop from Dell again. Laptop Battery barely lasted a year and was told I had to buy another one that this was the normal life of battery. Bad Product!

This Dell Inspiron E1505 Battery just died on me. it wont charge more than 37% and now i have to buy another one…

The replacement products in Amazon review :

was skeptical buying this battery for my Dell Inspiron 1420, being it so cheap. Any computer store around where I live the batteries were over $150 for standard capacity and even more expensive [...]. This is a great buy.
The only downside is that it is a heavy Dell Inspiron 1420 Battery and was not fully charged when I first put it in.
Otherwise, it works well and gives me 4 hours to float around on battery.  

Since receiving (Amsahr-quick delivery) and using this Dell Inspiron 1720 Battery and charging and discharging it approximately 6 times, it has performed excellently and with high performance. It also fits perfectly like the original, and was priced very reasonable.
