手机出问题的8个轻松解决方法
手机维修的基本技巧本节主要介绍一些手机维修的基本常识、故障的大致范围及手机维修的一般技巧，以便上网者能快速维修常见故障手机。一、自动开机加上电池后，不用按开/关键就处开开机状态了。主要由于开/关键对地短路或开机线上其它元器件对地短路造成。取下手机板，用酒精泡后清洗，大多可以解决此故障。 二、自动关机（自动断电）1．振动时自动关机这主要是由于电池与电池触片间接触不良引起。2．按键关机手机只要不按键盘，手机不会关机一按某些键手机就自动关机，主要是由于CPU和存储器虚焊导致，加强对存储器CPU及存储器的焊接一般可解决问题。3．发射关机手机一按发射键就自动关机，主要是由于功放部分故障引起，一般是由于供电IC（或功放控制）引起此故障。
三、发射弱电、发射掉信号1．发射弱电手机在待机状态时，不显弱电，一打***，或打几个***后马上显示弱电，出现低电告警的现象。这种现象首先是由于电池与触片接口间脏了或接触不良造成；其次是电池触片与手机电路板间接口接触不良引起；再其次就是功放本身损坏引起。2．发射掉信号手机在待机状态时，信号正常，手机一发射马上掉信号，这种现象是由于手机功放虚焊或损坏引起的故障。 四、漏电手机漏电是较难维修的故障。首先判断电源部分、电源开关管是否烧坏造成短路。其次判断功放是否损坏。再其次，漏电流不太多的情况，给手机加上电源1～2分钟后用手背去感觉哪部分元件发热严重，此元件必坏无疑，将其更换。如果上面的方法仍没有解决故障，就只有去查找线路是否有电阻、电容或印刷线短路。 五、不入网不入网可分为有信号不入网、无信号不入网两种情况。目前在市场上爱立信系列、三星系列的手机，只要其接收通道是好的，就会有信号强度值显示，与有无发射信号无关，其它系列手机必须等到手机进入网络后才显示信号强度值。对其它系列的手机在判断故障范围时，给手机插上SIM卡，调菜单，用手动搜寻方法找网络，此时，能找到网络，证明接收通道是好的，是发射通道故障引起的不入网；用菜单方法找不到网络说明接收通道有故障，先维修接收通道。六、信号不稳定（掉信号）由于接收通道元器件有虚焊所致（摔过的手机易出现此故障）。主要对接收滤波器、声表面滤波器、中频滤波器和接收IC等元器件进行补焊，大多能恢复正常。七、软件故障归纳起来，手机软件故障主要现象有：1.手机屏幕上显示联系服务商、返厂维修等信息都是软件故障，重写码片资料即可。2．用户自行锁机，但所有的原厂密码均被改动，因此出厂开锁密码无用，重写码片资料即可。3．手机能打出***，但设置信息无记忆、显示黑屏、背光灯不熄、电池正常弱电告警等故障，在相关的硬件电路正常情况下，软件也能引起这些故障，必须重写码片资料。
八、根据手机电流情况判断故障原因1．不开机，按开机键电流表指针微动或不动，这种现象主要是由于开机信号断路或电源IC（不工作）引起。2．不开机，按开机键电流表针指示电流，比正常值200mA左右小了许多，但松开开机键电流表指针回到零，这种现象说明电源部分基本正常、时钟电路没有正常工作或者CPU没有正常工作。3．不开机，按开机键电流表指针指示电流200mA左右稍停一下马上又回到0mA。这是典型的码片资料错乱引起软件不开机故障。4．按开机键有20～30mA左右漏电流，表明电源部分有元器件短路或损坏。5．按开机键有大电流漏电表明电源部分有短路现象或功放部分有元器件损坏。6．加上电池就漏电，首先取掉电源集成块，若不漏电，说明故障由电源IC引起；如仍漏电，说明故障由电池正极直接供电的元器件损坏或其通电线路自身短路（进水易出现此故障）造成。根据电池给手机供电原理查找线路或元器件（电源滤波电容、电源保护二极管有时会出现短路）。7．手机能工作，但待机状态时电流比正常情况大了许多。这种故障的排除方法是：给手机加电，1～2分钟左右用手背去感觉哪个元件发热，将其更换，大多数情况下，可排除故障。如仍不能排除，查找其发热元器件的负载电路是否有元器件损坏或其它供电元器件是否损坏。8．手机无信号强度指示或无网络，可根据电流表指针摆动情况判断故障的大致范围。正常情况下，在手机寻找网络的同时，电流表指针不停地摆动，幅度有10mA左右。如果电流表指针摆动正常，仍无网络，这种故障多见于诺基亚、摩托罗拉等手机，故障范围大多在发射VCO部分或功放电路部分；如电流表指针摆动不正常也无信号强度指示，则故障范围大多在接收VCO、本振部分或接收通道其它部分。

fromGaussian calculations can fail with various error messages. Some error
messages from .out and .log files - and possible solutions - have been compiled
here to facilitate problem solving.
These are divided into:
&a title="Convergence problems: " href="file:///E:/&–°&&&&–‡&&&&¤¹/Trouble%20shooting%20Gaussian%20calculations%20&€”%20Norwegian%20High%20Performance%20Computing.htm#convergence-problems"&Convergence problems
&a title="Errors in solvent calculations: " href="file:///E:/&–°&&&&–‡&&&&¤¹/Trouble%20shooting%20Gaussian%20calculations%20&€”%20Norwegian%20High%20Performance%20Computing.htm#errors-in-solvent-calculations"&Errors in solvent calculations
&a title="ERROR MESSAGES IN LOGFILES
" href="file:///E:/&–°&&&&–‡&&&&¤¹/Trouble%20shooting%20Gaussian%20calculations%20&€”%20Norwegian%20High%20Performance%20Computing.htm#error-messages-in-logfiles"&Errors in log files
ERROR MESSAGES IN OUTPUT FILES
Syntax and similar errors:End of file in ZSymb. Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l101.exe
Solution: The blank line after the coordinate section in the
.inp file is missing.
Unrecognized layer "X". Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l101.exe
Solution: Error due to syntax error(s) in coordinate section
(check carefully). If error is "^M", it is caused by DOS end-of-line characters
(e.g. if coordinates were written under Windows). Remove ^M from line ends using
e.g. emacs. To process .inp files from command line, use
sed -i 's/^M//' File.inp
(Important: command does
not work if ^M is written as characters - generate ^M on
command line using ctrl-V ctrl-M).QPERR --- A SYNTAX ERROR WAS DETECTED IN THE INPUT LINE.
Solution: Check .inp carefully for syntax errors in
keywordsRdChkP: Unable to locate IRWF=0 Number= 522. Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l401.exe
orFileIO operation on non-existent file. [...] Error termination in NtrErr: NtrErr Called from FileIO.
Solution: Operation on .chk file was specified (e.g.
geom=check, opt=restart), but .chk was not found. Check that:
%chk= was specifed in .inp
.chk has the same name as .inp
.chk is in the same directory as .inp
run script transports .chk to temporary folder upon job start. Run scripts
downloaded here should do this. The combination of multiplicity N and
M electrons is impossible. Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l301.exe
Solution: Either the charge or the multiplicity of the
molecule was not specified correctly in .inp.
Memory and similar errors:Out-of-memory error in routine RdGeom-1 (IEnd=
1200001 MxCore=
2500) Use %mem=N MW to provide the minimum amount of memory required to complete this step Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l101.exe
orNot enough memory to run CalDSu, short by
1000000 words. Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l401.exe
or[...] allocation failure: Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l1502.exe
Solution: Specify more memory in .inp
(%mem=Nmb). Possibly, also increase pvmem
value in run script. Especially solvent calculations can exhibit allocation
failures and explicit amounts of memory should be specified.galloc: could not allocate memory.
Solution: The %mem value in .inp is higher
than pvmem value in run script. Increase pvmem
or decrease %mem.Probably out of disk space. Write error in NtrExt1
Solution: /scratch space is most likely full. Delete old
files in temporary folder.
Convergence problems:Density matrix is not changing but DIIS error= 1.32D-06 CofLast= 1.18D-02. The SCF is confused. Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/linda-exe/l502.exel
Solution: Problem with DIIS. Turn it off completely, e.g.
using SCF=qc, or partly by using
SCF=(maxconventionalcycles=N,xqc), where N is the number of
steps DIIS should be used (see ).Convergence criterion not met. SCF Done: E(RHF) = NNNNNNN
A.U. after 129 cycles [...] Convergence failure -- run terminated. Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/linda-exe/l502.exe
Solution: One SCF cycle has a default of maximum 128 steps,
and this was exceeded without convergence achieved. Possible solution: In the
route section of input file, specify SCF=(MaxCycle=N), where N
is the number of steps per SCF cycles. Alternatively, turn of DIIS (e.g. by
SCF=qc) (see ).
Problem with the distance matrix. Error termination via Lnk1e in /pkg/gaussian/g03/l202.exe
Solution: Try to restart optimization from a different input
geometry.New curvilinear step not converged. Error imposing constraints Error termination via Lnk1e in /pkg/gaussian/g03/l103.exe
Solution: Problem with constrained coordinates (e.g. in
OPT=modredun calculation). Try to restart optimization from a slightly different
input geometry.Optimization stopped.
-- Number of steps exceeded, NStep= N [..] Error termination request processed by link 9999. Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l9999.exe
Solution: Maximum number of optimization steps is twice the
number of variables to be optimized. Try increasing the value by specifying
OPT=(MaxCycle=N) in .inp file, where N is the number of
optimization steps (see ). Alternatively, try to
start optimization from different geometry.
Errors in solvent
calculations:AdVTs1: ISph= 2543 is engulfed by JSph= 2544 but Ae( 2543) is not yet zero! Error termination via Lnk1e in /global/apps/gaussian/g03.e01/g03/l301.exe
Solution: Problem is related to building of the cavity in
solvent calculations. One possible solution is to change the cavity model
(default in g03 is UAO, can be changed by adding RADII keyword in section below
coordinates in the .inp file, e.g. RADII=UFF, see ).
X has 2 bounds. Keep it explicit at all point on the potential energy surface to get meaningful results.
Solution: In UAO cavity model, spheres are placed on groups
of atoms, with hydrogens assigned to the heavy atom, they are bound to. If
assignment fails (e.g. because heavy atom-H bond is elongated), cavity building
fails. Possible solutions: a) use cavity model that also
assigns spheres to hydrogens (e.g. RADII=UFF) or b) Assign a
sphere explicity on problematic H atom (use SPHEREONH=N, see )
ERROR MESSAGES IN LOGFILES=&& PBS: job killed: walltime N exceeded limit M signal number 15 received.
Solution: Job did not finish within specified wall time.
Retrieve .out and .chk files from temporary folder /global/work/$USER/$JOB (or
$PBS_JOBID) and restart calculation if possible (using e.g.
opt=restart or scf=restart).cp: cannot stat $JOB.inp: No such file or directory
Solution: The .inp file is not in the directory from where
the job was submitted (or its name was misspelled during submission. If error
reads: cp: cannot stat $JOB.inp.inp, the .inp file was
submitted with extension).ntsnet: unable to schedule the minimum N workers
Solution: The value of %NprocLinda=N in the .inp file is
higher than the number of nodes asked for during submission. Make sure these
values match.Connection refused [...] died without ever signing in Sign in timed out after 0 worker connections. Did not reach minimum (N), shutting down
Solution: Error appears if you run parallel calculations but
did not add this file to your $HOME directory: .tsnet.config
containing only the line: Tsnet.Node.lindarsharg:
