When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

I would assume the wifi was built-in. If not, why not use any USB Wifi adapter!

SOURCE: hi grade laptop boot problem

crashing a few times in order to boot can be caused by corrupted boot files that Windows required.
Try do a "scan for bad sectors" checkdisk (Right click C: in My Computer, click Properties. Click Tools tab and then Check Now button, tick both option boxes and it should ask to reboot for the bad sector check. 8c484d1.jpg
You can also use HDD Regenerator to fix corrupted files. Read my other posts for details.

SOURCE: hi-grade laptop wont turn on but the fan runs and the wifi lights

When we talk about laptop won't boot up it is a hardware failure.

First of all, most of the hardware failures that are going to be presented in this article require you to disassemble the laptop and work on its internal components. Because of this, you need the required components to take the laptop apart (such as screwdrivers, etc.) and space, lots of space. If you don't have a workbench, then working on that large table in the living room should do it.

Second of all, you need to be extra careful about ESD (electrostatic discharge). Sure, this is important when working with a desktop system too, but you really shouldn't consider this as some sort of overreaction or waste of time. A few anti-static conductive bags should suffice. These are going to be useful when you take apart components from the laptop and you need a safe place to put them down.

If the laptop does not power on using the batteries, then try to power it using the AC adapter. Pay attention and see whether the LED on the laptop lights up, signaling that the adapter was detected. If yes, then your power jack works. If the notebook still does not power on, disassemble the laptop and remove the batteries. Look first for the CMOS battery and take it out.

Your best bet is that the problem is memory-related. What you need to do is re-seat the memory modules. If there are more than one, then try swapping them between each other and try different slots. Try booting again. If it does not work, then try running with only one module - this way, you can tell whether one is faulty.

Disassemble the laptop and remove the HDD, CD/DVD drives, and the modem and/or wireless card(s). If possible, take out the sound card module (if separate). To minimize the possible causes, you may disconnect the LCD panel as well. Try running this way. If it does boot, then try connecting each connector one at a time, booting up in between to localize the problem.

Good luck and take time to do a hard troubleshooting this trouble is not easy as well. You need to be care full in removing the some parts so that the other will not affected and being damaged.

SOURCE: Hi there,Does anyone know why an Hi-Grade 8615

This laptop is made by Mitac and sold by many computer companies (in the UK at least) such as Hi-Grade, Evesham and Medion.
This has a common fault which is being found on more and more laptop computers these days and that is that the video chip overheats due to lack of cooling and the cheap (WEII Compliant) lead free solder that is used to fix it to the motherboard cracks.
Common signs of this fault can be one or more of the following-
No Power light when charger connected
Battery not charging
Internal fan not running
And of course no picture
Repairing it is difficault. If you remove the bottom panel you will see a silver heat sink half under the plastic edge (this could so easily have been connected to the CPU heatsink arm and this of been avoided!). If you apply some light pressure to the top of it and switch your machine back on it usually will boot.
If it does and you want a fast fix then wedging some card between the top of the sink and the plastic casing may keep it alive for a while longer. If on the other hand your a pro or feel it's shi t or bust time then get a blow lamp and (like walking over broken glass) carefully heat the chip to reflow the solder beneth it. Do not apply any pressure to it when hot as the solder it is connected with is designed to be about 1mm from the motherboard surface. Pressing it will look like you have bitten into a hot dog and the mustard has spurted out both ends, except obviously with solder and a GPU (not so tasty!)
I shouldn't have to mention this but some people arn't so bright so please don't take offence: Remove the motherboard along with any cables, ram and the processor before attempting the blow lamp method!
It is actually professionally done this way except with a 'Rework Station) and not a blow lamp! I have however done it with an electric blow lamp I bought from Argos for £12 several times on various machines with all but one failing to revive.
Just as a note, the Xbox 360 RROD (Red Ring Of Death) is caused by the same issue. It can also be repaired using this method although there are safer alternatives in that case.
Hope I have helped some of you anyway. Please rate to let me know.
Phill.

My notino uL100 notebook laptop isnt working! PLEASE HELP!!!


Hello,

Do you get the message to press f10 at all during the boot process? If so please press f10 and follow the recovery procedures. All Hi grade systems without disks have a recovery partition built into the hard drive and you access this via the F10 key during boot up. Please let me know how you go with this.

HI-GRADE Intel Core T2080


Hi.
Intermittent faults like this are very common in laptops. It is most likely cracked soldering on the mainboard. Sometimes it can be repaired, or it may need a board replacement. Unfortunately, paying the big money doesn't mean high quality these days. Just look at the failure rate of Apple laptops as a good example. A friend of mine has had 16 failures in the top spec Macbook.
