Disassembly of the e-book Pocketbook 611
Yesterday I was left with a dead Pocketbook e-book, model 611.
Complaints
standardly “hung at the flashing” + “we didn’t touch anything!”
')
Anamnesis
The book really "hung", or rather, either the battery sat down at 0, or for some reason the software stopped displaying information on the screen. As was the technical information about the flashing, it remained on the screen ... The book is not even six months old, apparently the state of the new
Inspection
Rebooting does not help, shutting down does not help, connecting to power via USB (computer and RAM with different I from 0.25A to 1A) does not help, prolonged charging does not help, “flashing to the blind” does not help
Diagnosis
Everything is bad. Information about the breakdowns of such books is scarce, but on the whole, profile forums offer a conclusion - an unsuccessful modelfor losers, buy Amazon Kindle , shit happens.
Direction
In the morgue. It remains only an autopsy, with a weak hope of resurrection, as if it were a miracle) ... The book does not have any "user" compartments, the battery is built-in, which side to disassemble is incomprehensible. Youtube is silent and does not give a recipe ... 1 green hour double-sided screwdriver has produced a complete disassembly photo recipe to ...
Recipe under the cut
1. The plastic of the book is dull and good, on the "stern" forms something like a ledge-stiffener. In spite of this, the book bends a little, opening up to us the gaps indicating that the back cover is not firmly soldered to the case. Slightly bend the corner, penetrate the case by 1.5-2mm with a thin screwdriver and raise the angle ...
Only in the corners of the cover there are special ledges under the screwdriver. Starting from the end, you can damage the case before the cover with the effort goes away.
2. Having lifted one corner, carefully follow from it to the sides, bending back the end latches of the lid.
3. That opened the whole cover ..
Remove it ... Next elementary)
View of the front side of the board and the front side of the cover immediately after opening
View of the front side of the board and the back side of the cover
Fee close up
Connector with microSD card - book ROM. 2Gb card, 4 sections on it: 31Mb ext2 and 8Mb ext2 system, about 200Mb dictionaries, 1.4Gb FAT user internal memory + 34Mb unallocated area at the end
Lithium Polymer Battery 1000mA * 3.7V McNair
CPU. In spite of deadness, at certain moments it even heats up a little.
Flex from the board on the E-Ink display. A modern connector, like on laptops - we raise the dark holding bar by 90 degrees and release the cable. Reverse assembly
SanDisk microSD card. Gold Mark - Chinese OTC?
Battery connector. It joins and detaches not “from itself” / sideways, but upwards. Pull the wires is unacceptable and useless. Gently pick up something not solid from below, and it will easily detach. Also surely connects when installed over the contacts and lightly clamped.
Along the edges of the board there are 8 small screws under the usual cross-head screwdriver. After removing them, the board is easily detached, and the device splits into 4 parts (case with screen, buttons, board, back cover)
The front panel and the back side of the board. As you can see, the screen is completely disconnected from the board, but the image does not disappear. The cognitive-dissonant feature of E-Ink.
Buttons separately
Back of the screen
Summary: sturdy hardware performance, interesting and versatile design, high-quality materials ... all this is ruined by miscalculations in software that can suddenly turn it into just a piece of plastic, make the owner cry over a paper book ... Now I'm looking for an image from the internal memory card of the working instance , in order to fill it with the one under consideration and finally find out whether this dead state is due to an update failure, or a problem in the device components
UPD20121110: a programmer from a Pocketbook contacted me, and gave some valuable and non-trivial recommendations for reviving the reader ... On Monday I will try to execute them if the owner does not take the book for the 2nd attempt to carry to the SC) I will update the tail of the topic by result
UPD20121114 : the device is repaired , hooray! With the help of Mikhail Boyko, a Pocketbook programmer, we managed to revive the book, for which he had great respect and advantages in karma ... it’s a pity that such a person has not yet been invited to Habr. Share an invite?
