battery upgrade
Here is what I have done. I have downloaded the zip file 0.90. In that zip are a file folder entitled src. Also there are three files: battery.o, powerMgr and start.sh (actually 4, including the README). I have created the /lib/modules/2.4.19-rmk7-pxa2-irex1/kernel/drivers/irex folder and in the /irex folder I have placed the battery.o file. In the already existing /usr/bin folder I have copied the powerMgr file. In the /home/root folder I have placed the start.sh file. I have then turned off the device and turned it back on (reboot). I still only get 12 - 14 hours out of the batteries (2 - 2800s). Am I missing something? Am I supposed to do something with the /src directory and subfiles in the zip? PLEASE HELP THIS DUMMY!
Thanks Jim |

what am I doing wrong?
jharker:
I have installed the software exactly as you have described. I am using 2.12 firmware. I don't seem to get any more time out of the new batteries. Jim Boardman Quote:

Hi, jboardman--
I'm sorry it took me so long to respond! I've been really busy recently and I've been traveling for the last week, so I haven't even been checking the forums. I'm actually still on the road, but I finally had the time to check in. Based on what you said above, it seems like you've installed it correctly. You don't need to do anything with the files in the src directory, they're only there for people who want to compile it themselves or otherwise play with the source code. The first thing I'm thinking of is, do you have wireless or wired networking turned on? For example, if you have the "unbrickable" mod installed, your wired ethernet will automatically start when the iLiad boots up. Wired ethernet will more than halve your battery life -- that is, the iLiad uses about 2.5 times more current with wired ethernet on. You might also have something else installed that turns on ethernet or wireless and then fails to turn it off? Another possibility is: are you using an SD/MMC/CF card? These will also increase power drain. Let me know whether you've ruled out the above possibilities. If you have, I can send you a diagnostic program that will record the actual current drain and voltage while the iLiad is on. With a logfile from that we might get a hint about what's going on. If we rule out all other possibilities, then it's possible that your batteries are defective. But I think this is highly unlikely; there must be another explanation. (By the way, the modified powerMgr works by monitoring the battery voltage, so it should work correctly for any lithium-ion or lithium-polymer battery of any capacity.) Hope this helps! |

Thanks, J.
I do use a CF card, although I don't think I need it. I am just judging by the battery meter icon, and guessing that I am getting about 15 - 20 hours out of the batteries. Is there something I can do to see if everything is working properly? Can I request a reading while in the shell? And, I have another problem. I follow the instructions for installation of FBReader. The program seems to execute, but I find nothing in the Program folder when it finishes. Should the Program folder be on the device's main memory and not on the CF card? Thanks again for all your trouble. Jim |

Hmm... It's been a while since I used a CF card, but I recall that they use a fair amount of power. So it might be that 20 hours is about right. I have a diagnostic program kicking around somewhere... let me look for it and see if I can find it.
As for FBReader, I'm not sure about that, AdamB would be the person to ask, though. |

I just want to report successful battery replacement for Book Edition. I used the same batteries as jharker.
I want to add few notes: - The original batteries are not soldered in traditional way (can't be unsoldered with soldering iron), so the pipes of the old batteries have to be cut. - when soldering, use tip that is about 1.5 mm, the smaller tips will not heat well the battery pipes and the board contacts (on the battery controller board) - the length of the cable that connects the battery controller board to the main board is exact match for the original batteries size. Since the new batteries are longer, you have to be careful how much of the length of the battery pipes is left when soldering add how the battery board is bend over the batteries. - Without jharker's patch, the battery meter showed completely drained battery (as in laozhang case, however, when i applied the patch (i do have the dev pack & ssh installed), the meter show full, but the LED was red, so i charged until the led turned off, opened the case and mesure the the voltage. It was 4.15 V (on both batteries.) When i got the batteries, the voltage was 3.80 V and they got recharged in about 4 hours. One strange thing: one of the batteries during the charging was warm (about 40 °C) and the other was cool. I don't know the reason for this, since the they had exactly the same charge (3.80V), but it seems that is ok (the first charge cycle passed ok) Last edited by trotzky; 06-05-2009 at 01:34 AM. |

I am getting great battery life. It took about 4 or full charges to get there.

Hello Jharker, thanks for such a detail explain.
But after I chage replace the files, I meet something wrong. I need your help! After repalce the files, I power off my iliad 1st, then turn it on. Then I find the problem: - I can not use SD card.(I knew it might happen before I do the change. I do not mind.) - The indicator of battery on screen is always grey. It doesn't work. - I can not connect my iliad by putty or Wincp any more. Then I use mrxvt and run "ifconfig" in it. Previously, the ethernet ip address of ebook was shown, then I can connect to it by my computer. But this time, the informations below are shown on screen. Then I can not connect to my ebook. (I know the right ip, since I can check it on the Wireless Router) / # ifconfig eth0 Link encap: Ehernet Hwaddr xx:xx:xx:xx:xx:xx UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:0 (0.0 B) TX bytes:4130 (4.0 KiB) Interrupt:36 Base address:0x300 DMA chan:8 lo Link encap: Local Loopback intet addr:127.0.0.1 Mast: 255.0.0.0 UP BROADCAST RUNNING MULTICAST MTU:16436 Metric:1 RX packets:272 errors:0 dropped:0 overruns:0 frame:0 TX packets:272 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:9296 (9.0 KiB) TX bytes:9296 (9.0 KiB) What can I do now??

Hi, just wanted to say thanks for your excellent instructions and post! After having my 1st gen iliad for two years the original batteries had gone completely kaput. I threw it in a corner until I decided to check out replacement options when I stumbled upon this article. It was a fun (and simple!) hack and I'm really glad to have my iliad back for less than 40 bucks!!!! Thanks a bunch, nice work.

I'm another european Iliad owner that wants some battery packs but doesn't want to pay $75 for international shipping. Any suggestion?

Hi,
as you disconnected the battery pack, does the Iliad run without it being plugged in? Has anybody measured all the voltages at the connector? My Iliad does not start, Irex says it's probably the battery. I measured about 8V at red wire of the battery pack, but zero on white and blue, all against black. Both batteries seem to be full (charging stops, ~4V each). My device does not start, with the battery pack plugged in or not. (I only get a green light while pressing power) thanks p.s. irex wants EUR 125 in advance for replacing battery unit without being sure that this is the problem.

How old is your Iliad? I had the same problem and had to send mine back. Remember, the 125 EUR includes shipping. I paid, sent the Iliad back, and seven days later (yes, only seven days) I got my Iliad back from IREX in perfect operating order!

Battery seems just not plausible to me. I can't believe the device won't run when the battery is unplugged. Voltages seem normal when it's plugged in.
