Hai ta2ctp
Its really appreciating that you have checked every posiibility. I guess the problem lies with the XP version you are using. Confirm wether it is a leagal verion or try installing from some other source.
Good luck

Hello All,

First of all, this is a rare source for information on Laptop repairs. CHEERS.

I have an ASUS L7300-G Laptop from back year 2000. (Pentium III KP 600/256 CPU)

After shutting off on a low Battery, it never came up again.

Symtom:
Press PowerOn, Powerlight comes on and stays on, charging light is on, hdd
light briefly lights up . You hear a little short noise from the drives, then silence.

Seems no bios startup activity. (no activity on bios-chip pins with scope).

Voltage-checks OK on 1.5V-cpu, 3.3v-memory, 5v-drives. Fan-voltage notok
(ie. not running)

i red before there are little chip-fuses to secure certain chips.
also i red, the cpu rarely dies.

i am pretty good in electronics, so i want to repair that "dam thing".

no experience on laptops though.

"dead laptop" seems to be a common problem and might be related to some motherboard circuit problem.

If Mr Sandip Golani comes back here to the forum, please give advice to the
"dead laptop" problem.
more narrow: what makes bios not start. and.. no fan spinning, howto detect a dead cpu.

other inputs of corse welcome!

regards from germany
tom

Added after 53 minutes:

reading through some postings,...

I spilled liguid (coffee, wine etc) over the laptop or left it in the rain:

liquid mostly harms the keyboard and the tft-display.
most likely the keyboard.
(all mechanical problems).

a display may still function in part, so does a keyboard.
Solution: replace it. there is no REAL fix. (or life with it).

If your laptop gets wet, turn it off, leave it drying on the heating
for a couble of days. Then turn it on again.

CMOS memory:
I guess in ourdays configuration is not saved in cmos-memory any more.
rather in eerom or flash. The battery you find on the motherboard is
just to supply the realtime-clock to work when device is off.
(absolutely uncritical!)
on the other hand i am hearing a lot about "Resetting CMOS". hmmm

CRASHED bios:
if you are lucky you can unplug the flash-chip and get it reprogrammed externally.
otherwise ? unsolder it? (dont know, you might be able to reprogram incircuit)


NOISY fans:
after years of operation its time to cleanout the dust in your laptop.
a vacuum-cleaner is a good choice to suck out the dust.
or even open it up and do a clean job.
a noisy fan indicates its plastic wheel is somehow deformed by the time and heat.
propably time to exchange.
also the attachment of the heatsink to the cpu might need attention if laptop
gets hot. there is a thermal-paste between the cpu and heatsink to conduct the heat.
this gets old by the time and could need a fresh new coating.
heat-paste available in electronic stores.

all mechanical parts need some service after a while.
cdrom cleaning the head with alcohol f.e.

Thank you

Hai Roger, You should be able to run your Laptop with the Power supply, without battreies. If you cant, the problem may be with the switching section on the mother board, Faulty RAM, or a dead CMOS battery. Good luck

Hi Sandip,
This is P K Sharma.
I've Q6600 with DG31PR, coolermaster 500w psu, 2GB Transcend 800mhz RAM.
The problem is mobo is getting very hot 87C. I placed heatsink on southbridge and placed " fan on both chips. See this thread for full effort details http://www.thinkdigit.com/forum/showthread.php?t=96907
Is there any solution, now I am thinking of installing 120 mm over mobo. As I watched that mobo runs cool when I direct table fan over it. LOL

Do I have to replace mobo with other SLI one?

Thanks.

asus laptop repair tıps ıc

Can some one please help me with the problem I am having with my laptop. I have Sony VAIO PCG-K86P model laptop. recently started facing the power up problem,
halfway thru boot process, laptop suddenly switches off, some times I see the welcome screen and some times even the desktop screen loading the programs, but dies suddenly. I tried turning on the laptop only with powersupply by removing the battery completely, but didn't help. When I tried turning on the laptop on battery with power adapter disconnected, it worked fine but only lasted for a while till the battery dies, but what I observed is, if I connect the power adapter when the system is running on battery, it shuts off with in couple of mins. I have cleaned the heatsink and upgraded with new RAM and cleaned inside, which didn't help, can some one please suggest me what else I can try with the issue.

Thanks & Regards,

how to test motherboard charging circuit

Hi Pranam, thank you for the suggestion, will do that, but Its the same adapter that came originally with the Laptop.

laptop power circuit repair

Yes ...buddy..but measure the out put to be arround 19 volts..or the one specified on the laptop. In case you have a voltage higher than the one required, there are quite more chances of getting a shutdown due to excess voltage and heat for protection. Good luck
