Portable Power Options

I have been looking at two companies that sell external power supplies and batteries, The Battery Geeks and Tekkeon.

Lets start with The Battery Geeks offerings. First off, they offer a free battery audit. You fill out a simple form and they will email you with recommendations. For my Acer C110, they recommended their external battery and portable power supply. The external batteries come in two capacities, 118 and 130 WH. Since my Acer battery has a 27 WH capacity, theoretically these will increase battery time four or five fold. Since I get 2 hours with the Acer battery I should get about 10 hours with these models. The prices are $170 and $200 for these two batteries. They weight about 1.7 pounds and the dimensions are 7.75x4.5x.75(in).

The external power supply offered by The Battery Geeks also come in 118 and 130 WH as well as 200 WH. These power supplies are only a tad bigger (8.93x4.84x.87(in) 1.87 lbs) but offer more voltage outputs, 3 - 28 Vdc as opposed to only 15 - 21 Vdc for the batteries. The advantage is being able to power other devices other than the laptop. As you can guess, the prices are a bit more, $250 and $300 for the 118 and 130 WH versions.

Tekkeon offers the myPower All 3450 external battery which is rated at 50 WH which would theoretically last 4 hours when used with my Acer C110. Its a bit smaller than the battery geek devices (3.28 x 6.80 x .92) and much lighter weighing just under 1 lb. Also, with the smaller capacity its less expensive $120. And unlike the Battery Geeks external batteries the myPower All has a USB port so anything you can charge via your computer USB port you can charge with this device. The disadvantage is that the 3450 will not charge my Acer internal battery. The Acer C110 is rated for 20 Vdc and the 3450 only charges devices that are rated for 16V or less.

Currently I am leaning toward the myPower All 3450 mainly because of the lower price and smaller size but may hold off right now. In the two weeks I have been using the Acer I have not had a need for the extra juice. At home and at work I am mostly plugged in and at the end of my daily train commute I usually have 30% left on the internal battery. Where this device would be needed is when I travel for off site training or conferences.

I'll keep you posted.

My Acer Tablet Not in Perfect Condition; But No Complaints

As you can imagine, my Acer C110 is not in perfect condition I bought it in August 2004 and at that time it was even a refurbished unit. One of the reported weak spots is the swivel and latching mechanisms. Mine is holding up strong. However the tip of the latch that latches the screen to the base when in the traditional closed laptop position broke off right before I switched over to the Samsung Q1 in February. Also, the rubber protectors for the port replicator and USB ports have separated from the device. In both cases I think crazy glue will do the trick. Or I can order replacements at this site I found.

The most annoying problem is a recent one. I recently removed the keyboard to clean it and now, everyone once and a while a key will stick, usually the own arrow and the delete buttons. Physically they look fine and don’t appear stuck and the only way to clear the problem is to hit another key. So perhaps there is an electrical connection problem or software issue. I will post in one of the forum and see if anyone else has had this problem and knows of a fix.

Overall, not too bad for a 3+ year old device!

BTW, I am typing this on the train something I couldn’t have done with the Q1P since it doesn’t have the attached keyboard and inking is almost impossible with all of the movement on the train.

First Day Using the Improved Acer

Tuesday was the first day I only used my improved Acer C110. I did power up the Q1P but only to get a file that I needed to transfer to the Acer. Overall it went well. The biggest plus is the larger screen. Compared to the 7" screen of the Q1P, the 10" screen is huge. I can easily work in all my applications, never having to go to full screen mode. While the screen quality and brightness are not even in the same league as the Q1P, it worked fine. I was actually impressed using it this morning to read the New York Times via their reader software. With the brightness set at only 17 (on a scale of 20) and sitting right next to a window the viewing experience was quite pleasant. I even read in portrait mode which I never used to do as the view tended to bother my eyes. While it initially did bother me I decided to try it for the duration of the train ride and apparently I got used to it. This is good news for me as its much easier to hold the Acer in one hand in portrait mode rather than landscape mode.

Battery life is decent at about 1 hour and 45 minutes with screen brightness set at 17 and WIFI on. However, this morning I used the device on the train with WIFI off and had 29% battery capacity left after using it for at least an 1 1/2 hours.

At the desktop I am using the same setup as I used for the Q1P. I do have the Acer port replicator but now that I only have three hookups (power, USB and external monitor) the desk just seems less cluttered without the replicator. However that may change if I connect external speakers. The Acer speaker is no where near the quality of the Q1P. However, since I don't listen to audio much at my desktop I will probably keep the desk less cluttered without the speakers.

As for using the Tablet screen as opposed to the Q1Ps touch screen, I think it will take some time to get used to. Its strange to see the cursor move all over the place as I move the pen across the screen. It also seems a bit sensitive since if I leave the pen hovering above an object such as the minimize or close buttons it will engage them after just a few seconds without my even touching the screen.

I also updated two drivers, the Wacom driver and Intel graphics driver. Lastly, I went to the advanced controls for the microphone and enabled "microphone boost' which improved the performance of the microphone.

Acer C110 Upgrade Status

I installed the Samsung 160GB hard drive and the Intel 2915 wireless network adaptor which now gives me rev G wireless. Using the service manual I was able to make these upgrades easily. After installing the new hard drive I did a clean reinstall of windows XP tablet edition as well as all of the programs I use so the process took some time but overall it was quite easy.

Having rev G wireless is very nice compared to the native rev B the Acer C110 came with and the new hard drive is very quiet. The original hard drive was quite noisy mainly due to it taking a 6 mile trip on the roof of my car a few years back. It was at least in a protective case, but nothing very sturdy. Fortunately it didn't fall off the car thanks to the roof rack but I was still very surprised it actually survived. With the noisy hard drive gone and since the Acer doesn't have a fan (the Q1P does) the whole tablet is very quiet.

As for processing speed, the Acer never really seemed that slow but now with a clean install and faster hard drive (5400 v. 4200 rpm) the overall response seems faster.

With the clean install using the Acer recovery disks there were many Microsoft updates including XP SP2. However, after installing all of the updates the floating tip didn't appear. That was easily resolved by downloading the program floatingtip.exe. Also, specific to the Acer C110, I downloaded and installed a utility (wchange) that allows you to turn on and off the wireless card. This is nice to have when in tablet mode as the hardware button is hidden. I also changed the drive format from FAT to NTFS. This was easily done using this guide.

Improvements I would still like to make are to battery life and screen quality. The battery life ranges from 1.5 hours to 2 hours depending on screen brightness and power status of the wireless card. The screen quality really pales compared to the Q1P. Not sure if there is anything I can do about the screen quality but I have some ideas about battery life. I'll keep you posted.
