Kobo Forma: Alguém ficou sem poder carregar de um dia para o outro

Fri, 26 Dec 2025 10:33:56 -0700

Boas

A ultima vez que carreguei o meu Kobo durou 15 dias até baixar aos 10%, infelizmente distrai me e chegou aos três por cento, quando eu fui pôr a carregar apareceu a mensagem “por favor carregar eREADER“ e a partir desse dia apesar de ter carregado com vários cabos diferentes carregadores diferentes nunca mais passou de um ecrã negro com essa frase, é estranho como é que de um dia para o outro isto acontece.

Isto aconteceu há mais alguém, e como é que resolveram, não me apetece comprar um KOBO novo quando este estava a funcionar muito bem.

Liguei o meu Kobo Nia por uma noite inteira à ficha e ele carregou até aos 100%. No entanto, com cada descida de 1% de bateria, o dispositivo diz que está sem bateria e pede para ser carregado. Já tentei reiniciar o dispositivo, verificar a porta de carregamento e usar cabos e carregadores diferentes, mas o problema persiste.

Onyx Boox E-reader: Boox Max2 requires heating

Mon, 13 Apr 2026 05:06:41 -0700

This is not a question -- this is a quick note on my attempt to replace the battery in Boox Max 2 (a 1000 Euro device), Maybe it will help someone out there. My device had a thick layer of hot-melt glue below the rim, gluing the unit shut and hiding screws behind that need to be removed to access the battery. The glue had no function in water-proofing the device, it only appeared to be there to prevent self-repair. If you can't lift the rim with a blade, do not attempt further and use a hair dryer/heat gun to soften the glue or send the unit to Onyx. The battery inside is soldered to the motherboard. One can cut the cables and solder to the cables. The white cable did not need to be connected to a battery protection board to power up the unit. I was able to power my up with a lab power supply set to 3.8V (a this setting, the battery shows at 50% full). The unit draws as much as 1.2A during power up.

I will never buy an e-reader again w/o checking its repairability score. At least not for this amount of money,

P.S. If anyone wants parts from the damaged unit, let me know. The motherboard seems OK. I am in Europe.

Kobo Libra 2: Screen white and light flashing

Fri, 13 Mar 2026 11:01:14 -0700

Hi, I tried to upload a file with Calibre and the Libra 2 stopped working. I tried to reset it, but screen became white and flash began lightening. Now I can turn it on and off, but basically nothing happens, but screen is white and light is flashing. When plugged, PC recognized something but is not able to identify the device. Any idea? Thanks.

Kobo Clara Colour: Replaced Screen is Faint/Grainy?

Sun, 22 Feb 2026 14:39:03 -0700

I completed the screen replacement without issue. However, when I powered it up the screen has a grainy, or faintness to it. I did the Vcom calibration and nothing changed. Is there something else that should be done, or is this a faulty screen?

Kobo Libra Colour N428: Kobo Libra Colour Stuck on "Please Recharge" Screen - Even After New

Fri, 30 Jan 2026 10:49:14 -0700

Hello iFixit Community,

I need help troubleshooting my Kobo Libra Colour e-reader. It's completely stuck on the "Please recharge" screen and won't respond, even after trying multiple fixes including a brand-new battery. The white LED charging indicator lights up, but the screen never changes.

What I've Tried So Far:

Multiple wall chargers (5V/2A) and USB-C cables (known good ones)
Charging undisturbed for 24-48+ hours on both old and new batteries
Soft reset: Power button held 20-30 seconds (LED blinks)
Manual/factory reset: Page turn button + power button held 30 seconds while charging
Battery cycling (unplug/replug 20+ times while charger connected)
Inspected USB-C port (clean, no visible damage)
Verified new battery connector fully seated, correct model/compatible replacement

Current Symptoms (Same with Both Batteries):

White LED illuminates when charging
Screen stays frozen on "Please recharge" - no progress, no boot
Not recognized by PC (no drive mount)
No response to any button combinations

Theory: Suspect charging controller, display driver, motherboard, or firmware brick. Battery swap ruled out power issue since symptoms identical.

Questions:

Anyone fixed this exact "dead screen but LED works" issue on Libra Colour?
Could it be the battery management system (BMS) needs special reset?
Mainboard replacement viable?
JTAG/short-to-reboot possible, or is it bricked?
Kobo support dead-end?

Kobo Libra Colour: The repair part is not working for my motherboard…

Tue, 25 Nov 2025 22:26:36 -0700

Dear iFixit Support Team,

I recently used iFixit parts/tools to repair my Kobo eReader, and after the repair the device is not working correctly. I would like to ask for assistance.

Product(s) purchased: Kobo Libra Colour Screen Assembly - Genuine
Purchase date: 18 Nov 2025

Issue description:
After installing the replacement part(s) following the iFixit guide, the Kobo eReader powers on but remains stuck on the “Welcome to Kobo” screen and does not respond to touch. The device cannot proceed to the setup or home screen.

Steps taken:

Rechecked the internal connections and reseated all relevant cables
Fully charged the device
Tried forced restart and manual reset according to Kobo’s instructions

The problem still persists.

Could you please advise:

Whether this behaviour could indicate a defective replacement part or a known compatibility issue.
Whether the repair part you provide is adaptable for my motherboard…as you haven’t mentioned and give me the choice before I place the order..
What diagnostic steps you recommend to confirm if the part is faulty.
Whether a replacement or refund is possible for the part if it is determined to be defective, and how to proceed with RMA from Hong Kong.

I can provide detailed photos of the installation and a short video showing the issue if required.

Thank you for your help, and I look forward to your reply.
