Known Issues

Unit does not turn on but battery charges or frequently encounters errors during boot sequence

CMOS NiMH battery has died

• The rechargeable NiMH CMOS battery has a finite cycle life and will fail
• If infrequently used the NiMH CMOS battery will leak

Solutions

• Remove or replace NiMH CMOS battery
• Repair any corrosion damage from leaks

Unit lags heavily or freezes or turns off suddenly when running demanding applications

Thermal interface material between CPU and heatsink is bad

• The thermal paste will eventually dry out
• The thermal paste will eventually be 'pumped-out'
• This leads to poor thermal performance and overheating

Solutions

• Check rear fan is functional
• Clean dust from heatsink & fan
• Replace thermal paste

Unit does not turn on or charge, PSU LED does not illuminate

Mains charger PSU has failed

• Unknown failure mode

Solutions

• Attempt to repair original charger (difficult, glued/ultrasonically welded case)
• Buy new charger with correct specifications with NEC charger adapter (or spice existing charge cable)

Disassembly Notes

• The plastic in this device is thin and extremely brittle, the design relies on the rigidity of the PCBs to support the weight of the device, you are very likely to break plastic pieces when attempting a repair.
• There are a number of thin flat-flex cables and locking/hinged FFC ZIFs in this device, they are difficult to manipulate and prone to damage.
• There are a number of high density interconnects in this device, they must be disconnected and connected by applying even force without twisting the connectors to avoid damage.
• Use ESD safe equipment
